摘要

针对目前基于区块链的溯源算法主要通过同态加密及零知识证明进行隐私保护，使溯源信息难于实现动态共享这一问题，提出基于属性加密的区块链数据溯源算法。为实现交易隐私的动态保护，基于 Waters 所提CP-ABE方案设计适用于区块链的策略更新算法，完成交易隐私的动态保护。为实现区块内容可见性的动态更新，基于策略更新算法设计区块结构，实现区块内容可见性的动态更新。通过安全性及实验仿真分析表明，所提算法可以在完成保护交易隐私的同时，实现溯源信息动态共享。

Abstract

To solve the problem that the blockchain-based traceability algorithm mainly used homomorphic encryption and zero-knowledge proof for privacy protection

making it difficult to achieve dynamic sharing of traceability information

a blockchain data traceability algorithm based on attribute encryption was proposed.In order to realize the dynamic protection of transaction privacy

the strategy update algorithm applicable to block chain was designed based on the CP-ABE scheme proposed by Waters to achieve dynamic protection of transaction privacy.In order to realize the dynamic update of the visibility about block content

based on the strategy update algorithm

the block structure was designed to achieve the dynamic update about the content visibility of the block.The security and experimental simulation analysis show that the proposed algorithm can realize the dynamic sharing of traceability information while completing the protection transaction privacy.
