基于区块链技术的数据交换安全性研究

Research on the Security of Data Exchange based on Blockchain Technology

随着区块链技术的飞速发展,区块链由第一阶段1.0的可编程货币逐渐发展至3.0版本的可编程社会。区块链的关键是去中心化和降低信任成本,防伪造和可追踪性,为解决大数据问题提供了一种思路。基于此,提出了一种基于区块链技术的可扩展性隐私保护数据共享方案来研究和解决数据交换系统的安全问题。方案中使用Paillier算法加密用户数据,整个Paillier密码体系的时间基本都很短,但是效率很高。该方案的内部安全分析显示,系统具有超强的安全性。

With the rapid development of blockchain technology,blockchain has gradually developed from the programmable currency of the first stage 1.0 to the programmable society of version 3.0.The key to blockchain is to decentralize and reduce the cost of trust,as well as anti-counterfeiting and traceability,which provides an idea for solving big data problems.Therefore,this paper proposes an extensible privacy protection data sharing scheme based on blockchain to explore and solve the security problems of data exchange system.In this scheme,Paillier algorithm is used to encrypt user data.The time of the whole Paillier cryptosystem is basically very short,but the efficiency is very high.The internal security analysis of this scheme indicates that the system has superior security.
