基于区块链的属性加密细粒度访问方案
Blockchain-Based Attribute Encryption Fine-Grained Access Scheme
摘要: 个人数据隐私安全一直是近年来研究的热点，然而现有的数据访问模型，多数是基于第三方中心化结构，虽然在一定程度上可以解决数据隐私保护和细粒度访问问题，但是同样会造成数据的泄露和经济成本的增加。在本文中，一种基于区块链的去中心化的结构被提出，通过结合新兴技术属性加密、区块链BC、智能合约SC和IPFS分布式存储，解决了数据安全和细粒度访问问题，保证用户之间数据交易的隐私性，使个人用户对数据拥有绝对的控制权。最后，通过仿真实验，证明论文提议的框架是可行并且有效的。
Abstract: Personal data privacy security has always been a hot research topic in recent years. However, most of the existing data access models are based on a third-party centralized structure. Although data privacy protection and fine-grained access problems can be solved to a certain extent, they will also cause data leakage and increase economic costs. In this article, a decentralized structure based on blockchain is proposed, which solves the problem of data security and fine-grained access by combining emerging technology attribute encryption, blockchain BC, smart contract SC, and IPFS distributed storage and ensures the privacy of data transactions between users, so that individual users have absolute control over the data. Finally, through simulation experiments, it is proved that the framework proposed in the thesis is feasible and effective.
