The purpose of the research is to find ways to increase the efficiency of the nanosatellite constellation (network) in the conditions of replenishment and retirement of spacecraft during operation in orbit based on a self-organizing mesh network, in which routing is carried out dynamically based on the connectivity of network elements. Methods are based on decision-making techniques, systems analysis, and decentralized control principles, enabling a nanosatellite network to independently reconfigure itself to meet changing operating conditions and task requirements. Using the properties of self-organization and adaptive control methods (distribution and responsiveness to change), the nanosatellite constellation maintains a configuration of satellites capable of exchanging data and service information. A two-level network reconfiguration method has been developed, enabling proactive changes to the composition of nanosatellites based on historical assessments of the quality and strength of transmitted signals. Algorithms for route list generation and route analysis have been developed, which can be executed autonomously on each nanosatellite in the constellation. Results . The developed reconfiguration method enables asynchronous addition and deletion of satellites from the network based on received or discovered information about their status and connections between satellites. It is shown that the decentralized approach has linear time complexity for the most critical algorithms for updating and constructing network routes. Conclusion . The developed reconfiguration method and algorithms for managing a nanosatellite constellation form the basis for developing network software that allows each satellite to autonomously make decisions about modifying its status and route list.

The proliferation of satellite constellations in Low Earth Orbit necessitates a shift away from centralised control, and towards autonomous, decentralised systems for Space Situational Awareness. Crucially, this transition requires establishing trust between satellites in a zero-trust environment, independent of a central authority. Distributed Ledger Technologies offer a resilient foundation for decentralised operations. However, in the domain of space systems, a unified framework that securely integrates consensus-based validation with cooperative Orbital Determination remains unexplored. To address this gap, the Autonomous Cooperative Consensus Orbit Determination framework is introduced, designed for on-board, peer-to-peer validation of orbital data. A novel consensus mechanism, Proof of Inter-Satellite Evaluation, is at the framework's core, and is tailored for resource-constrained systems. Measurement quality is evaluated by using a two-sided chi-squared test on the Normalised Innovation Squared, which is derived from the statistical output of an Extended Kalman Filter. This test is employed to provide a defence against both sensor faults and sophisticated spoofing attacks by penalising data that is either excessively noisy or unnaturally perfect. This statistical evaluation is weighted by a dynamic, long-term reputation score that rewards consistent, high-quality data contributions and penalises untrustworthy behaviour. Simulation results demonstrate that the framework effectively secures the network's distributed ledger by confirming valid transactions and robustly rejecting those from faulty or malicious nodes. The resulting architecture is presented as a viable solution for enabling resilient and autonomous cooperative space systems.

UNITY-6G introduces a AI-natively framework that unifies terrestrial (TN), non-terrestrial (NTN), and non-public networks (NPN), treating connectivity, computing, and intelligence as interdependent resources. The architecture utilizes an Inter-Domain Management Orchestrator (IDMO) based on Service-Based Management Architecture (SBMA) principles to coordinate services across heterogeneous domains. A core pillar of the framework is its AI-native design through autonomous agentic AI workflows following a standardized MS–AE–DE–ACT (Monitoring, Analytics, Decision, and Actuation) logical patterns. To enhance resource efficiency and sustainability, the architecture integrates Digital Twins (DT) for proactive system modeling and semantic communications to prioritize task-relevant information transfer. Security is addressed through a Trust Architecture leveraging Distributed Ledger Technology (DLT) for cross-domain auditability. The framework's utility is validated through proof-of-concepts targeting sustainable disaster handling, immersive XR/holographic communications, and time-sensitive services for Industry 4.0. The presented advances establish a foundation for the continuous development of high-performance, autonomous 6G systems.

ABSTRACT Securing satellite data transactions is critical as satellite communication supports global connectivity, navigation, earth observation and aviation. Sensitive inter‐satellite data requires robust protection, and aircraft‐ground station links must prevent hazards. Vulnerabilities could breach security protocols, compromising confidentiality and incurring legal consequences. This paper presents the first integration of proof‐of‐authority (PoA) consensus, ERC1155 multi‐token standard and threshold cryptography for satellite data transactions. Unlike prior blockchain‐based proposals that rely on single‐key encryption or energy‐intensive proof‐of‐work (PoW), our system (i) uses ERC1155 to batch different data types in one contract (reducing gas costs by 40%), (ii) distributes private keys via Shamir's secret sharing (k‐of‐n) to eliminate single points of failure and (iii) implements dynamic share rotation during orbital handovers (98% success). Simulations show 12.5 ms average latency, 50 messages/second throughput and 40% lower gas costs versus PoW systems (0.0006 ETH/message). Threshold cryptography increases cracking complexity to operations, while PoA, under our simulation assumptions, achieves 100% detection of man‐in‐the‐middle attacks and 0% success for reentrancy/Sybil attacks. Dynamic share recovery during orbital handovers attains 98% success, outperforming traditional methods in resilience and efficiency.

Frequent handovers between satellites, and the lack of a central (on-board) state database, challenge the delivery of communication services from Low-Earth-Orbit (LEO) satellite constellations. Traditional blockchain protocols to maintain distributed state are unsuitable for on-board deployment as they do not take the moving dynamics and inter-satellite links of constellation orbits into account. In this paper, we propose LeoDist, a distributed ledger for LEO constellations. We introduce novel concepts, such as leader-handover, neighbor synchronization, and service area gossiping to meet the challenges of this dynamic environment. To the best of our knowledge, LeoDist is the first distributed ledger on board LEO satellites to support the core routing, state synchronization and consensus blockchain protocols while accounting for orbital dynamics and coverage area. We show using a lab testbed with the NASA core Flight System (cFS) that LeoDist is able to route, gossip, reach consensus, synchronize state and process transactions efficiently, offering 3-4 orders of magnitude faster leader failover and handover compared to Raft, up to 171 distributed transactions per second, and broadcasting across a constellation of 95 satellites in less than 50 ms on standard UDP/IP links.
The emerging Web3 has great potential to provide worldwide decentralized services powered by global-range data-driven networks in the future. To ensure the security of Web3 services among diverse user entities, a decentralized identity (DID) system is essential. Especially, a user's access request to Web3 services can be treated as a DID transaction within the blockchain, executed through a consensus mechanism. However, a critical implementation issue arises in the current Web3, i.e., how to deploy network nodes to serve users on a global scale. To address this issue, emerging Low Earth Orbit (LEO) satellite communication systems, such as Starlink, offer a promising solution. With their global coverage and high reliability, these communication satellites can complement terrestrial networks as Web3 deployment infrastructures. In this case, this paper develops three hybrid satellite-ground modes to deploy the blockchain-enabled DID system for Web3 users. Three modes integrate ground nodes and satellites to provide flexible and continuous DID services for worldwide users. Meanwhile, to evaluate the effectiveness of the present hybrid deployment modes, we analyze the complete DID consensus performance of blockchain on three hybrid satellite-ground modes. Moreover, we conduct numerical and simulation experiments to verify the effectiveness of three hybrid satellite-ground modes. The impacts of various system parameters are thoroughly analyzed, providing valuable insights for implementing the worldwide Web3 DID system in real-world network environments.
Recently, the promising unmanned aerial vehicle (UAV)-assisted wireless networks (UAWNs) have emerged by advocating the UAVs to provide wireless transmission services. However, owing to the ever-growing volume of data traffic and the untrusted network operation environment, efficiently and securely assigning limited bandwidth for high-quality wireless communication between UAVs and mobile users poses a significant challenge. To address this challenge, we propose a novel secure UAV-bandwidth allocation scheme to provision reliable wireless transmission services for mobile users in UAWNs. Specifically, we first introduce a novel blockchain-empowered framework for secure bandwidth allocation, designed to automate payment processes and deter malicious activities through the immutable logging of transactional and behavioral data. Wherein, a smart contract is designed to regulate the honest behaviors of both mobile users and UAVs during bandwidth allocation with a distributed manner. Besides, a delegated proof-of-stake (DPoS) with reputation consensus protocol is presented to ensure the authenticity and efficiency of the decision-making process. Further, we apply the Stackelberg game theory to model the dynamic of the bandwidth allocation between mobile users and UAVs. In this game, the UAVs act as game leaders to determine the bandwidth price, while each mobile user acts as a game follower, making decision on the bandwidth request. We utilize the backward induction method to derive the optimal strategies of both parties, culminating in the identification of the Stackelberg equilibrium of the formulated game. Finally, extensive simulations are carried out to show the superiority of the proposed scheme over conventional schemes in terms of security, efficiency, and fairness in bandwidth allocation.

This paper introduces the Hybrid Submarine/Space Architecture to Ensure the Information Security of Telecommunications (HEIST), a system leveraging distributed ledger technology to securely reroute disrupted undersea cable communications to satellite networks. HEIST’s components enable the integration of ground and satellite heterogeneous networks into an ad-hoc and on-demand broadband mega-constellation, maximizing the non-terrestrial rerouting bandwidth to reduce the impact of failures on service quality and availability in submarine fiber optic networks.
This study, conducted in 2024, explores the potential of blockchain technology to enhance data integrity in space communications and operations. With the growing complexity and reliance on satellite networks for global connectivity, Earth observation, and deep space exploration, ensuring tamper-proof and secure communication is critical. The research proposes a blockchain-based framework that integrates satellites, ground stations, and spacecraft as decentralized nodes, addressing existing security challenges such as data tampering, unauthorized access, and signal jamming. Based consensus combining Proof of Stake (PoS) algorithm with Practical Byzantine Fault Tolerance (PBFT) processes is introduced to optimize security and latency in space environments. The feasibility of the framework is evaluated through simulations and case studies, demonstrating its effectiveness in mitigating space-specific threats, with practical implications for missions such as NASA's Artemis program. The study concludes that blockchain offers a transformative solution for securing space communications and urges stakeholders to pilot such technologies for future space operations.
Satellite communication systems (SatCom) is a brand-new network that uses artificial Earth satellites as relay stations to provide communication services such as broadband Internet access to various users on land, sea, air and in space. It features wide coverage, relatively high transmission rates and strong anti-interference capabilities. Security authentication is of crucial significance for the stable operation and widespread application of satellite communication systems. It can effectively prevent unauthorized access, ensuring that only users and devices that pass security authentication can access the satellite network. It also ensures the confidentiality, integrity, and availability of data during transmission and storage, preventing data from being stolen, tampered with, or damaged. By means of literature research and comparative analysis, this paper carries out on a comprehensive survey towards the security authentication methods used by SatCom. This paper first summarizes the existing SatCom authentication methods as five categories, namely, those based on cryptography, Blockchain, satellite orbital information, the AKA protocol and physical hardware respectively. Subsequently, a comprehensive comparative analysis is carried out on the above-mentioned five categories of security authentication methods from four dimensions, i.e., security, implementation difficulty and cost, applicable scenarios and real-time performance, and the final comparison results are following obtained. Finally, prospects are made for several important future research directions of security authentication methods for SatCom, laying a well foundation for further carrying on the related research works.
The Space-Air-Ground Integrated Network (SAGIN) is a pivotal direction for the advancement of the sixth generation mobile communication systems (6G), and blockchain technology has been recognized as a potential solution for secure spectrum sharing within SAGIN. However, the implementation of wireless blockchain networks encounters significant challenges, particularly limited throughput and scalability. These challenges are primarily due to the limitations of existing consensus protocols, which were designed for general distributed systems, struggling to adapt to highly dynamic SAGIN scenarios. An efficient and secure spectrum sharing framework can be established by leveraging delegated proof of stake (DPoS) and practical byzantine fault tolerance (PBFT). Accordingly, we propose SatBFT, a scalable consensus protocol that emphasizes the inclusion of satellites and employs a DPoS-PBFT mechanism tailored to SAGIN. The protocol is carefully designed to accommodate the various links in SAGIN and to manage coexisting interference. By adopting a multi-layer architecture, SatBFT introduces a comprehensive consensus framework that incorporates radio environment sensing, dynamic behavior evaluation and efficient block generation. Simulations based on the proposed security model, latency model, and spectrum utilization model confirm that SatBFT significantly enhances the overall performance of blockchain in SAGIN, achieving an optimal balance between efficiency, scalability, and security.
This paper tackles a low earth satellite governance paradox beyond the Kármán Line (100 kilometers above sea level): the same proprietary AI that keeps satellites safe also hides the reasoning states need to supervise private actors and assign responsibility. AI black-box compliance is now routine—operators disclose maneuvers but not the internal signals, thresholds, or telemetry transformations—leaving due regard, peaceful-use expectations, and fault analysis to operate on conjecture rather than evidence. The result is an accountability gap across core space-law instruments: Article VI of the Outer Space Treaty presumes continuing supervision; the Liability Convention relies on reconstructable causation; the LTS Guidelines anticipate demonstrable prevention measures. Terrestrial approaches offer partial assistance. The EU’s qualified transparency and the U.S. post-incident auditing travel unevenly off-Earth, and neither framework reliably reaches proprietary on-orbit autonomy. This paper shows with concrete operational scenarios (e.g., dynamic conjunction-thresholding, autonomous servicing approaches), provides an inevitable loss of public-law legitimacy and lack of protection for intellectual property. To address this, the paper proposes a dual-layer disclosure regime that protects legitimate trade secrets while restoring verifiable oversight. Layer 1—Regulatory Safe Rooms: accredited neutral venues conduct confidential code/model/telemetry review under treaty-backed non-disclosure, enabling certification, adversarial stress-testing, and forensic replay without commercial expropriation. Layer 2—Explainability Without Exposure: operators supply functional evidence—validated performance envelopes, adversarial test outcomes, decision bounds—augmented by privacy-preserving attestations (e.g., zero-knowledge proofs) in lieu of source disclosure. Implementation follows a “pressure-valve” path: condition launch licensing, frequency assignments, and mission approvals on participation now; seek UNCOPUOS endorsement later through a model protocol that harmonizes Artemis practices with non-signatories and codifies a TRIPS-compatible IP-Transparency Equilibrium Clause. The payoff is pragmatic rather than utopian: traceability sufficient to make due regard and liability doctrines workable again; incentives preserved for R&D; and a template that can translate to other thin-sovereignty domains (deep-sea, Antarctic, high-altitude autonomy) where algorithmic opacity currently outruns public law.
Recent revolutionary advancements in the services as observed with the use cases of Industry 5.0, consumer electronics 2.0/smart devices 2.0, digital healthcare ecosystem, Internet-of-Things (IoT), advanced digital finance/currency, and Non-Terrestrial Network (NTN) expansion, to name a few, have resulted in a spectacular growth in the number of wireless-connected devices. Subsequently, this has drastically increased the demands for network capacity, channel capacity, reliability, privacy, and security provisions. Despite that, the 5 th Generation (5G) of wireless communication networks has introduced various innovative services such as Ultra-Reliable Low Latency Communication (URLLCs), Massive Machine Type Communication (mMTCs), and Enhanced Mobile Broadband (eMBB). These services only support isolated operations and the requisite reliable service delivery remains a challenge. The Beyond 5G (B5G)/6 th Generation (6G) wireless networks aim at simultaneously providing multiple integrated services through intelligent network operations with ultra-high speed and reliability supporting integrated NTN and terrestrial networks. However, the prospect of such an extensively connected decentralized 3D wireless network also foresees security concerns, underscoring the necessity for seamless and infrastructurefree (decentralized) security solutions. The conventional security mechanisms are considered inadequate to ensure the security provisions of such extensive, decentralized, and heterogeneous networks. Physical Layer Security (PLS) is a promising technique to extend seamless and infrastructure-less security solutions, ensuring the availability, confidentiality, and integrity of legitimate transmissions. This paper provides a comprehensive overview with tutorials and presents the state-of-the-art of PLS, focusing mainly on NTN wireless communications. Furthermore, current research challenges, open issues, and future research directions are also thoroughly discussed in an amalgamation of various emerging 6G technologies. Finally, we provide an overview of implementation challenges in NTN and potential solutions to support the standardization progression of NTN in upcoming releases of 3 rd Generation Partnership Project (3GPP).

Abstract Satellite swarm networks have occupied a prominent position in many modern applications due to their low cost, simplicity of design, and flexibility. Reliability is an influential factor in the design of satellite networks with different structures. Usually, small satellites are based on COST components, which may reduce continues operability due to the lack of using backup system on board the sagecraft. Any failure in one subsystem means a complete loss of the function and data stored in this subsystem; hence the need for a reliable and applicable solution for this matter is a crucial topic. Using the redundancy strategy in satellite swarm networks increases reliability and availability. Blockchain is characterized by using a distributed ledger which enables the database to be replicated across nodes in the network and results in increasing transparency, security, and trust. This paper suggests adoption of blockchain technology in distributed multi-satellite mission swarm networks to provide a high level of reliability and availability of the entire system; the blockchain is usually used to secure system transactions in multilayer approach by storage of the key parameters in more than one node; here we suggest the adoption of this approach not only to secure satellite network transaction, but also to increase system reliability so that failure of one node can be recovered by other nodes. We compared this approach with similar traditional networks that do not use blockchain. The results show a higher reliability efficiency of 95.3% for applying blockchain technology compared to 64.3% without the use of blockchain, as well as a higher availability of 99% compared to 91%.
In the 6G era, space–air–ground integrated networks (SAGINs) can provide ubiquitous coverage for Internet of Things (IoT) devices. Multiaccess edge computing (MEC) and blockchain are two enabling technologies, which can further enhance the services capabilities of SAGINs, where MEC demonstrates a notable capability in efficiently minimizing both the task execution delays and system energy consumption, and blockchain can provide trust guarantee for task offloading and wireless data transmission among the entities operated by different operators in SAGIN. In this article, we present an MEC and blockchain enabled SAGIN architecture, which consists of two subsystems. In the MEC subsystem, a satellite and multiple unmanned aerial vehicles (UAVs) act as the edge nodes to provide IoT devices with computing power. Moreover, the satellite serves as the block generator and the client, and the UAVs serve as the consensus nodes of the blockchain subsystem. We intend to minimize the energy consumption within the network, which is achieved through the IoT devices’ task segmentation, the UAVs, and satellite’s bandwidth allocation among their served IoT devices. And moreover, the computing power of UAVs and the satellite also allocated in task processing and blockchain consensus. Considering the high dynamics of the network, it is impossible to obtain real-time and accurate channel information, so we remodel this problem as a Markov decision process, and propose a low-complexity adaptive optimization algorithm based on the deep deterministic policy gradient (DDPG). Our simulation results indicate that the proposed algorithm exhibits commendable performance in minimizing the network energy consumption and DDPG agent’s accumulated reward maximization.
In this paper, we present a decentralized network protocol, Space Network Protocol, based on Communication Satellite Services. The protocol outlines a method for distributing information about the status of satellite communication services across the entire blockchain network, facilitating fairness and transparency in all communication services. Our primary objective is to standardize the services delivered by all satellite networks under the communication satellite protocol. This standard remains intact regardless of potential unreliability associated with the satellites or the terminal hardware. We proposed PoD (Proof of Distribution) to verify if the communication satellites are online and PoF (Proof of Flow) to authenticate the actual data flow provided by the communication satellites. In addition, we also proposed PoM (Proof of Mesh) to verify if the communication satellites have successfully meshed together. Utilizing zero-knowledge proof and multi-party cryptographic computations, we can evaluate the service provisioning parameters of each satellite, even in the presence of potential terminal or network node fraud. This method offers technical support for the modeling of distributed network services.
Spectrum data sharing is a prerequisite for obtaining spectrum situation and achieving dynamic spectrum sharing. However, current spectrum data sharing mechanism lacks ownership confirmation and proper incentive mechanism, which impedes data sharing among untrusted participants. In this paper, we propose an non-fungible token (NFT)-enabled spectrum data sharing model, where the data asset is created as an NFT to confirm the ownership and data transactions are conducted through the transfer of NFT ownership, with the transaction process recorded on the blockchain. We model the interactions among all participants as a Stackelberg game, and the optimal pricing and purchasing strategy are determined through Nash equilibrium analysis. Simulation results show that when the demand of spectrum data requesters (SDRs) remain constant, the profit of spectrum data owners (SDOs) with less data will gradually increase to a ceiling point by increasing its data supply, and then drop down due to the supply imbalance. As the budget of SDR increases, SDRs with lower budgets will experience a reduction in profits yet still manage to access a certain level of resources.

The space-air-ground integrated networks (SAGINs) are pivotal for modern communication and surveillance, with a growing number of connected devices. The proliferation of IoT devices within these networks introduces new risks due to potential erroneous synergistic interactions that could compromise system integrity and security. This paper addresses the challenges in coordination, synchronization, and security within SAGINs by introducing a novel static program analysis (SPA) technique using zero-knowledge (ZK) proofs. This approach ensures the detection of risky interactions without compromising sensitive source code, thus safeguarding intellectual property and privacy. The proposed method overcomes the incompatibility between SPA and ZK systems by developing an imperative programming language for SAGINs and a specialized abstract domain for interaction threats. The system translates network control algorithms into arithmetic circuits suitable for ZK analysis, maintaining high accuracy in detecting risks. Evaluations of real-world scenarios demonstrate the system’s efficacy in identifying risky interactions with minimal computational overhead. This research presents the first ZK-based SPA scheme for SAGINs, enhancing security and confidentiality in network analysis while adhering to privacy regulations.
Operators of low-Earth-orbit (LEO) non-geostationary satellite networks, also known as mega-constellations, are required by current regulations to share all available satellite spectrum. This paper proposes a consensus mechanism to facilitate spectrum sharing with accountability by multiple operators, a subset of which may even be adversarial. A distributed ledger is used to securely record and track the state of consensus on spectrum usage, including interference incidents and the corresponding responsible parties. A key challenge is that operators generally do not have initial agreement due to noise in their analog measurements. To address this, two categories of spectrum-sharing solutions are studied in detail. The first category employs an exact Byzantine fault tolerant (BFT) agreement model; the second category utilizes an approximate BFT agreement model. Practical considerations were taken into account regarding the BFT agreements, substantiated by numerical findings on the feasibility of the proposed solutions within the context of non-geostationary orbit satellite networks (NGSO).

The quantity and diversity of stakeholders in space is increasing and centralised management of their assets is becoming more complex. New technologies in Web3 such as Decentralised Autonomous Organisations (DAOs) can bridge the communication gap with neutral and automated systems, and distribute currently centralised processes that are inherently decentralised by nature. One of these processes is Satellite-based Emergency Mapping (SEM) for Disaster Response Management (DRM). With automated decision strategies and transparent ledgers, a fairer and more accessible system can be built to handle the increase in stakeholders as well as the increasing number of natural disasters occurring. A DAO also address' the key issue with the current SEM process, such as decreasing the current three days wait, required to produce the necessary processed and analysed data for end users, after the disaster occurs. Moreover, with fleets of satellites belonging to different governmental and private organisations, a specific central authority cannot be identified to manage the process in an efficient and equitable way. The paper discusses the need for a more decentralised and automated system for DRM by presenting evidence of current bottlenecks and lays the foundations of the first DAO for on-orbit assets management and demonstrates which Web3 technologies could further improve SEM in this first phase of charter activation.
In this letter, a layered multi-chain spectrum blockchain architecture is proposed for Space-Air-Ground Integrated Network (SAGIN) to significantly reduce system overhead and aggregated interference. Considering the dynamic characteristics of SAGIN, nodes can make hand off between different blockchains based on the interference conflict graph to maintain aggregated interference below the threshold. To further improve spectrum utilization while avoiding harmful interference caused by spectrum trading in SAGIN, a spectrum trading mechanism is proposed, which jointly considers spectrum pricing, deployment location, and transmit power optimization. Simulation results verify the effectiveness of the proposed spectrum blockchain architecture and trading mechanism.

The fusion of terrestrial radio and satellite communications will result in a world completely connected with sixth-generation (6G) networks. But there is a limitation of power and space available on satellites due to low computing power, limited storage space, and insufficient security occur. It is critical to utilize information storage and access protection in satellite networks efficiently to prevent data tampering and alteration. Satellite communications play an increasing role in global communication networks, creating security problems. Based on the Quantum Key Distribution (QKD) protocol, this proposal suggests a security and authentication method for satellite communication networks. A wireless and heterogeneous network architecture utilizes both open-source and commercial hardware to enable communication. The three stages of registration, authentication, and cancellation facilitate communication. As data is transmitted to satellites from ground stations, all measurements of significance are then logged on a decentralized blockchain. All certifications generated by rogue nodes are subsequently cleared from the blockchain by ground stations. It has been suggested that the technology be used with upcoming 6G networks, as well as the Internet of Things, self-driving cars, and other rapidly expanding applications.
