With the development of educational modernization, digital technology has become a key force driving educational progress. As a decentralized, secure and reliable technology, blockchain has application potential in educational resource management, information management and the construction of basic platforms. At present, the cross-disciplinary integration in design faces many challenges, such as the problem of disciplinary barriers, the difficulty in protecting resource property rights, technical obstacles, the high cost of resource sharing, and the lack of a dynamic monitoring and evaluation system, etc. This paper studies the connotation, characteristics of blockchain and its coupling in interdisciplinary integration, designs an interdisciplinary integration resource platform based on blockchain, including network architecture, functions, learning coins and supply levels. This platform, through technological approaches such as distributed ledgers and smart contracts, enhances the effectiveness of cross-disciplinary integration, improves the level of copyright protection, reduces sharing costs, and realizes the automated operation of the regulatory system, providing new ideas and practical methods for the high-quality development of design education.
The essence of āblockchainā is a shared database in which information stored is un-falsifiable, traceable, open, and transparent. Therefore, to improve the security of private information in medical systems, this article uses blockchain technology to design a method to protect private information in medical systems and effectively realize anti-theft control of private information. First, the Patient-oriented Privacy Preserving Access Control model is introduced into the access control process of private information in medical systems. Next, a private information storage platform is built by using blockchain technology, and information transmission is realized using standard cryptographic algorithms. In this process, file authorization contracts are also used to guarantee the security of private information and further prevent theft of medical private information. Our simulation results show that the storage response time of this method is kept below 1,000 ms, and the maximum information throughput rate reaches 550 kbit/s, which indicates that this method has strong performance in information storage and transmission efficiency. Moreover, the reliability and bandwidth utilization of data transmission across domains is higher, so the method has higher information security control performance and superior overall performance.
Based on the cloud platform, the concept and importance of double-precision teaching in wisdom teaching is analyzed, and the basic framework of online and offline wisdom teaching based on blockchain technology is constructed in this paper. Based on the characteristics of blockchain such as security and decentralization, an accurate learning resource teaching model based on knowledge representation of learners and teaching resources is proposed. A double-precision collaborative strategy of accurate perception of wisdom teaching demand and accurate supply of resources is proposed. The framework of wisdom teaching is constructed, in which the accurate perception of wisdom teaching demand and the accurate supply of resources based on big data technology is analyzed. Based on blockchain technology, tracking the learning records of learners at each stage of learning is helpful. It effectively promotes the distribution and sharing of learning resources, efficiently bridges teaching resources and learning requirements, and provides more accurate, personalized learning support, and services for learners. It provides a secure data access strategy for both teachers and learners. The precise wisdom teaching framework based on blockchain technology has far-reaching practical value for the efficient development of online and offline teaching.

Student status management is a key part in university information construction and an important basis for talents certification. The emergence of blockchain technology provides a new way to improve the student status management system. Blockchain is a distributed ledger technology in nature, with its decentralized and nonītamperable features, the security and authenticity of student information can be ensured. Based on the application of blockchain technology such as smart contracts in "Smart Campuses", this paper proposes and designs a decentralized student status management systim. With Fabric framework, we developed a prototype of student status management system its demonstraiton.
In order to solve the problem of illegal memberās tracking attack, which caused by the vehicle unitsā privacy disclosure in vehicular ad hoc networks (VANETs), a vehicle identity authentication protocol based on lightweight group signature was proposed by analysis of topology and communication characteristics of VANETs in this paper, which can authenticate the vehicles anonymously in a fast and efficient way. The protocol has five stages. In the initialization phase, the public/private key pairs and system parameters of the group were generated by the VANETs system, then the group public key and system parameters were distributed to the on-board units by the roadside auxiliary facilities. The group private key was kept by the group manager. When a vehicle unit entered VANETs, the unitās own identity was submitted to the group manager by the blind signature. A group certificate would be distributed to the vehicle unit by the group manager when authentication passed. In the cooperative communication stage, the vehicle member who owned the group certificates signed the state information with the valid certificate and group public key, then sent it to the nearby vehicle units by the car sensors, and achieved cooperative driving with surrounding vehicles. In the message verification stage, only can the legal vehicle members open the received status information by using group public key, but couldnāt know the true identity of the message sender. In this way, the anonymous communication among vehicles was realized. In the stage of signature verification, when a vehicle unit broadcasted a false message for the purpose of exclusively using road resource and caused traffic accident, the group manager can open the signature of the message by using the group private key, and traversed the corresponding vehicle members to carry on the accountability. The innovation of the paper was the usage of improved lightweight group signature technology, which could ensure that the length of group public key and group signature didnāt depend on the number of group members. Zero knowledge proof was also used as a means of membership authentication which improved the speed of authentication among the members. The security of the protocol was analyzed and proved mathematically in this paper, and a LAN simulation platform composed of 100 PC machines was built to simulate the cooperative communication among vehicle units in VANETs. The experimental results showed that authentication time of the protocol was about 7 ms among 100 vehicle users. The performance of the proposed protocol is superior to the contrasted schemes. It greatly reduced the storage and calculation burden of the vehicle units during the process of identity authentication.
