针对人们在日益增长的数字化交互过程中越来越多地出现隐私直接或间接泄露的问题,主要研究基于区块链网络建立一套链上数据安全共享体系,基于密文策略的属性加密的访问控制算法以及同态加密算法实现链上数据的可靠共享,提出了一种链上数据共享架构,最后进行了仿真实验,并分析了实验结果。这项工作有效解决了恶意参与方利用区块链的交易透明性进行数据分析的问题,并保证了用户数据在共享流程中的隐私安全。
In view of the increasing number of people in the digital interaction process of direct or indirect disclosure of privacy issues
the establishment of a set of data security sharing system based on blockchain network
the access control algorithm based on ciphertext-policy attribute-based encryption and the homomorphic encryption algorithm provides reliable chain data sharing were mainly researched.Data sharing on chain architecture for data sharing on the chain was proposed.Finally
simulation experiments were carried out
and the results of experimental data were analyzed.The work effectively solves the problem of malicious parties using the transaction transparency of blockchain for data analysis and ensures the privacy security of user data in the sharing process.
