Pengamanan Data Teks Dengan Menggunakan Algoritma Zero-Knowledge Proof

Rozali Toyib, Yulia Darnita

Keamanan data sangat penting dilakukan dalam menjaga kerahasiaan informasi itu sendiri, terutama bila informasi tersebut hanya boleh diketahui pihak yang tertentu saja. Pengiriman data atau informasi tanpa dilakukan pengamanan akan beresiko terhadap penyadapan. Sehingga informasi yang ada di dalamnya dapat mudah diketahui oleh pihak-pihak yang tidak berhak, dan hal seperti itu sangat merugikan.Hingga saat ini, kriptografi merupakan salah satu solusi untuk menjamin keamanan dari suatu informasi. Zero Knowledge Proof (ZKP) merupakan protokol kriptografi yang dapat digunakan seseorang untuk membuktikan kepemilikan seseorang (prover) akan suatu informasi rahasia kepada orang lain (verifier), tanpa perlu mengungkapkan informasi tersebut atau memberikan cara bagi orang lain untuk mengetahui rahasia tersebut. Hasil pengujian adalah Zero Knowledge Proof membagi satu aliran data menjadi blok-blok kecil Masing-masing blok ini dienkripsi secara terpisah. Dalam implementasi tanpa bukti pengetahuan, kunci untuk mengenkripsi hanya akan berada pada pengguna, dan dengan itu, ia akan dapat mengenkripsi dan mendekripsi informas, Algoritma zero knowledge proof adalah metode yang unik dimana pengguna dapat membuktikan kepada pengguna lain bahwa dia tahu informasi tambahan.
 Kata Kunci: Keamanan ,data,penyadapan ,Zero-Knowledge proof

The Challenge of Cryptocurrency in the Era of the Digital Revolution: A Review of Systematic Literature

Izwan Amsyar, Ethan Christopher, Arusyi Dithi, Amar Najiv Khan · 5 authors

Money is clearly a primary need of every human being that cannot be avoided, human needs can be realized by using money. Seeing from the lack of systematic literature review papers discussing cryptocurrency, this is a challenge as well as the main purpose of this paper. Along with the development of modernization and globalization which has now entered the industrial era 4.0 revolution there is a blockchain based technology, Cryptocurrency. Cryptocurrency is one of the developments of the blockchain that is often used as a decentralized digital currency. The word Cryptocurrency means a virtual currency that has no physical form, and Cryptocurrency also means that the transaction currency cannot be seen and is safe. This digital currency has many types such as Bitcoin, Ethereum, Litecoin, Monero, and many other types. Although it has no physical form, this currency functions the same as conventional currencies in general and has an exchange rate. Exchange rates on Cryptocurrency fluctuate which means unexpected, this is often exploited by traders. Cryptocurrency transactions in the form of forwarding from one individual to another individual online, therefore they deal directly without a third party. Every technology has advantages and disadvantages aside from efficiency and convenience, Cryptocurrency has the disadvantage of not having the authority responsible for dealing with all problems that occur in all transactions, and money laundering crimes also often occur, this is a challenge for how to utilize Cryptocurrency and blockchain technology in the current era of globalization.

Implementation of Smart Contracts Ethereum Blockchain in Web-Based Electronic Voting (e-voting)

Ajib Susanto

The increasing of digital technology today has helped many people to fulfill their needs. But the election system, still conventionally using paper in its implementation. Elections in general still use a centralized system, where there is an organization that manages it. Some of the problems that may occur in traditional electoral systems are that there are organizations that have full control over the database and system, so the possibility of hacking the database is quite a big opportunity.Blockchain innovation is one arrangement that can be utilized in light of the fact that it has a decentralized framework and the whole database is duplicated by all clients. Blockchain itself has been used by Bitcoin and Ethereum cryptocurrency which is known as a decentralized system. By using the blockchain in database recording on an e-voting system can reduce one source of fraud that is database manipulation. This study discusses the recording of voting data using blockchain technology. The implementation of Smart Contracts contained in the Ethereum Blockchain will be implemented to create this voting system

Investigating the Requirements for Building a Blockchain- Based Achievement Record System

Bakri Awaji, Ellis Solaiman, Lindsay Marshall

A trusted achievement record is a secure system that aims to record and authenticate certificates as well as key learning activities and achievements. This paper intends to gather important information on the thoughts and outlooks of stakeholders on an achievement record system that uses blockchain and smart contract technology. The system would allow stakeholders (for example employers) to validate learning records. Two main aims are investigated. The first is to evaluate the suitability of the idea of building a trusted achievement record for learners in higher education, and to evaluate potential user knowledge of blockchain technology. This is to ensure that a designed system is usable. The second aim includes an interview conducted with a small group of participants to gather information about the challenges individuals have when creating, and reviewing CVs. Overall, 90% of participants agreed that there was a strong need for a trusted achievement record. In addition, 93.64% of respondents stated that they felt it was invaluable to have a system that is usable by all stakeholders. When tackling the second aim it was found that a primary challenge is lack of knowledge of blockchain and its complexity. From the employers' perspective, there is a lack of trust due to inaccuracies when students describe skills and qualifications in their resumes.

Certificate validation using blockchain

Mayuri Nagare, Aadi Mahalle, Digvijay Dakhore, Mrs. Soudamini Somvanshi · 5 authors

Conventional certificate verification, whether paper-based or backed by a centralized digital registry, remains exposed to forgery, single points of failure, and slow manual cross-checking between issuers, holders, and verifiers. This paper presents a decentralized, blockchain-based framework for issuing, storing, and verifying academic and professional certificates that addresses these weaknesses without placing the full document on-chain. Each certificate is reduced to a SHA-256 hash, signed with the issuing institution's RSA private key, and recorded through an Ethereum smart contract, while the original file is retained off-chain on IPFS and referenced by its Content Identifier. Only institutions that pass a unanimous, vote-based onboarding process administered by a validator consortium are permitted to issue certificates, which constrains the system to a trusted-issuer model while preserving decentralization across the validator set. A hash-mapped Bloom Filter sits in front of the blockchain query path and performs a fast probabilistic existence check, allowing forged or non-existent certificates to be rejected before an on-chain lookup is triggered. A prototype was implemented with Solidity smart contracts on the Ethereum Sepolia testnet, a Node.js/Web3.js application layer, and a React.js frontend with MetaMask-based authentication. Evaluation on the testnet shows that the Bloom Filter pre-check lowers the average lookup time for invalid certificates by roughly 87%, keeps verification of valid certificates under two seconds end-to-end, holds the false-positive rate below 0.5% for up to 50,000 stored certificate hashes, and reduces the gas cost of issuing a certificate to approximately 4.57 USD. These results indicate that combining consortium governance, cryptographic hashing, and probabilistic filtering yields a certificate validation pipeline that is simultaneously tamper-resistant, low-cost, and fast enough for real-time institutional use.

Karakteristik Blockchain Teknologi Dalam Pengembangan Edukasi

Sandy Kosasi

Proses pelaksanaan edukasi secara global hakekatnya belum dapat mengikuti perkembangan zaman saat ini. Berbagai permasalahan saat ini tengah dihadapi oleh sektor pendidikan, dalam hal ini sebut saja permasalahan verifikasi dan adanya pihak ketiga dalam penanganan sertifikat yang merupakan luaran mikro maupun makro dari sebuah proses pembelajaran. Adanya mercusuar tentang teknologi Blockchain, kerap disebut sebagai salah solusi revolusioner dari polemik pendidikan selama ini. Perpaduan antara bidang edukasi dan teknologi blockchain akan menciptakan revolusi baru dari industri pendidikan. Terdapat berbagai pencerahan dari solusi ini, namun dirasa belum cukup untuk menjelaskan karakteristik blockchain secara detail dari edukasi menggunakan blockchain, yang secara keseluruhan membahas tentang keberadaan blockchain for education berdasarkan kajian ilmu. Karakteristik blockchain ini dimasa depan akan sangat berguna sebagai platform literatur bagi peneliti yang akan memulai penelitian dasar dan terapan yang menjurus ke arah blockchain for education. Disamping itu, dari segi biaya, ruang penyimpanan, dan kecepatan teknologi blockchain akan diusulkan solusinya dalam bentuk framework. Alhasil, penelitian ini juga bisa menjadi landasan platform serta karakteristik blockchain baru sebagai cikal bakal pemerintahan berbasis teknologi blockchain.

Bitcoin Sebagai Alat Investasi

Miftahur Rahman, Akhmad Muhaini, Hasbi Ubaidillah

Bitcoin is a cryptographic-based digital commodity, also known as virtual currency or digital currency, which is used as a means of transactions and investments. In Indonesia the use of bitcoin is not merely a matter of technology, but has entered the realm of fiqh. An interesting phenomenon related to this is the response of several Islamic organizations and also study forums at Islamic boarding schools in Indonesia in addressing the bitcoin issue. Among them is Bahtsul Masail, the Nahdlatul Ulama Regional Manager (PWNU) in East Java in 2018. According to Bahtsul Masail's decision on the fiqh view of the use of bitcoin as a transaction and investment tool, it is legal, and may be used for muamalah. This is different from the results of the bahtsul masail in Ma'had Aly Hasyim Asy'ari Tebuireng Jombang, that bitcoin is classified as a virtual asset like dain (accounts receivable). And can be used as a legal transaction tool. But if bitcoin is used as an investment tool then the law is haram because the bitcoin exchange rate is very volatile. Based on this background, a problem arises, namely how to analyze the decision of Bahtsul Masail Ma'had Aly Hasyim Asy'ari about bitcoin and use what method to view bitcoin. The type of research used is library research. Using a normative legal approach (doctrinal), then the research is presented using descriptive techniques. In bahtsul masail using the ijtihad jama'i and ijtihad tatbiqi methods, in bahtsul masail using the term ilhaq, based on evidence, that bitcoin is equated with speculation (gambling), it is illegal.

Block-ED: The Proposed Blockchain Solution for Effectively Utilising Educational Resources

Shareen Irshad, Muhammad Nawaz Brohi, Tariq Rahim Soomro

Abstract In this day and age, access to the Internet has become very easy, thereby providing access to different educational resources posted on the cloud even easier. Open access to resources, such as research journals, publications, articles in periodicals etc. is restricted to retain their authenticity and integrity, as well as to track and record their usage in the form of citations. This gives the author of the resource his fair share of credibility in the community, but this may not be the case with open educational resources such as lecture notes, presentations, test papers, reports etc. that are produced and used internally within an organisation or multiple organisations. This calls for the need to build a system that stores a permanent and immutable repository of these resources in addition to keeping a track record of who utilises them. Keeping in view the above-mentioned problem in mind, the present research attempts to explore how a Blockchain based system called Block-ED can be used to help the educational community manage their resources in a way to avoid any unauthorised manipulations or alterations to the documents, as well as recognise how this system can provide an innovative method of giving credibility to the creator of the resource whenever it is utilised.

Application of Blockchain Technology for iLearning Student Assessment

Sudaryono Sudaryono, Qurotul Aini, Ninda Lutfiani, Firman Hanafi · 5 authors

Blockchain is the core technology used to create cryptocurrencies, such as Bitcoin. As one part of the fourth industrial Revolution since the invention of steam engines, electricity, and information technology, blockchain technology has begun to be applied in areas such as finance, judiciary, and trade. Blockchain technology uses decentralized, distributed and transparency techniques for data security. This research aims to determine the implementation of blockchain technology in the field of education, especially in the Data Security section. The study uses two methods namely the mind mapping method and literature review. The results of this study showed that with the presence of blockchain technology, the data is more secure from attacks from both inside and outside because it passes through two levels of security, namely encryption and decentralized data.

Blockchain Technology into Gamification on Education

Qurotul Aini, Untung Rahardja, Alfiah Khoirunisa

As we know, Indonesia has begun to enter the era of revolution 4.0 which in that era there were many changes in all fields including the presence of blockchain technology which began to be in demand. Including in the field of education, the changes that occur in the world of education today are so significant with the commencement of the abandonment of teaching methods that still use conventional methods. Keep track of tasks by book, face to face communication, which of course will cause many losses in a certain period of time, as many tasks that have long been buried become difficult to find when needed, and the possibility of manipulation of tasks is still great. The learning method is considered as a boring and insecure way, where students cannot explore learning because the collected files can still be manipulated by other parties. So from now on the application of learning methods is changed by the concept of gamification which relies on blockchain technology. The gamification learning method was created to compensate for the times when students preferred to play games rather than learning, therefore the gamification method could be applied to management education in higher education.

Utilization of Blockchain Technology for Management E-Certificate Open Journal System

Farida Agustin, Qurotul Aini, Alfiah Khoirunisa, Efa Ayu Nabila

The application of blockchain technology in e-certificates in the open journal system is needed to validate and distribute managed e-certificates in each journal issue. With tools in the form of conceptualized and managed blockcerts allows users to use and verify the authenticity of e-certificates that are closely linked to the blockchain. Observation on the open journal system and applied blockchain tools in the form of blockcerts as a place to issue e-certificates with guaranteed security so that e-certificates are verified as well as managed data. Issuance of e-certificates is still considered unsafe because it can be easily forged. Specifically, this study produced two benefits, namely: (1) Issuance of e-certificates in an open journal system is more verified, data is managed and there will not be duplications or even falsification of e-certificates. (2) The reputation of the open journal system is better with a sense of trust. This research uses library study method by implementing e-certificate in an open journal system with blockchain technology tools such as blockcerts. In order that the results of the e-certificate issuance go well and to avoid any crime that threatens the authenticity of the e-certificate, this blockchain is used to guarantee that the e-certificate is safe and not easily falsified, duplicated or even easily replaced by those not granted access rights. By using blockchain technology, the data collected will be well managed and not easily falsified.

Noor Abdalkarem Mohammedali

There is no uncertainty that the chroma currency is very popular for the transaction information stored in the block of blocks. To initiate the importance of blocking, there is only one distributed ledger in which data is stored, since many of the centers in the blockchain network limit enough records for these records. This document proposes a decision-making framework based on innovation to create a secure, unjustifiable, accurate and transparent framework for voter privacy. In addition, it is voted and declared in this context that the race has a short period of time, since it is automatically registered in the table. This framework also gives society confidence in its legislation when applying this technique. In this framework, an administrator can add a candidate and a voter to the block. In different hands, a voter can log into the framework and then decide in favor of a candidate that the details of the vote should be stored in the block. In addition, each square in the blockchain innovation that relates to the previous square contains the hash of the previous square, and each square contains explicit data based on the square footage. The hub is connected by a peer network in this framework, with all the hubs in the block site network that have a complete duplicate block.
