摘要
针对传统区块链平台数据保护机制不完善,区块链信息极易被篡改和丢失的问题,提出一个基于可搜索加密的区块链信息保护方案。首先对方案模型和具体加密算法进行设计,并对设计的算法然后对该方案的复杂度和安全度进行分析。基于上述方案和算法,利用Fabric联盟链平台数据,构建一个基于区块链可搜索加密的数据共享系统,并对该系统的整体架构、功能分区进行详细设计。最后,为测试系统的有效性,将搭建测试环境和实验环境,分别对系统功能和设计方案进行测试和实验。结果表明,设计的系统功能均可有效应用,将提出方案与其他经典算法方案进行对比后发现,提出的方案时间效率更高,且都得到了显著的提升。
In view of the problem that the traditional blockchain platform data protection mechanism is not perfect, the blockchain information is easily tampered with and lost.In this study, a searchable encrypted protection scheme for blockchain information was designed to prevent information tampering.The scheme model and the specific algorithm are first introduced in detail.The complexity and security of the scheme are then analyzed.Based on the above schemes and algorithms, a data sharing system based on Fabric alliance chain platform data is constructed with blockchain searchable encryption, and the overall architecture and functional partition of the system are designed in detail.Finally, in order to test the effectiveness of the system, the test environment and the experimental environment will be built to test and experiment the system function and the design scheme, respectively.The results show that the system functions of this study can be effectively applied effectively. After comparing the proposed scheme with other classical algorithms, the proposed scheme are more time efficient and significantly improved.
