摘　　要：为了解决传统区块链数据对称加密上传的弊端,基于Fabric平台,提出一种区块链网络数据动态结构加密的隐私保护可搜索加密方案。将可搜索加密框架分为数据拥有者、数据提供者和数据用户,通过对上传的区块链上传数据进行自适应加密和动态可重建加密,以此实现一种动态的双重安全可搜索加密,提高区块链网络数据的安全和检索效率。结果表明,所提方法关键词查询时间约为1.5 ms,动态更新时间约为100 ms;相较于常用可搜索加密方法,其复杂性更低、安全性较高。由此得出本加密方法促进了区块链在敏感数据领域的应用扩展,同时也为区块链数据共享提供了新的方向。In order to solve the drawbacks of traditional blockchain data symmetric encryption upload,based on the Fabric platform,a privacy-protected searchable encryption scheme for dynamic structure encryption of blockchain network data is proposed.The searchable encryption framework is divided into data owner,data provider and data user,by conducting adaptive encryption and dynamic reconstructable encryption on the uploaded blockchain data,thus a dynamic dual security searchable encryption is achieved to improve the security and retrieval efficiency of blockchain network data.The results show that the keyword query time of the proposed method is about 1.5 ms,and the dynamic update time is about 100 ms.Compared with common searchable encryption methods,it has lower complexity and higher security.Therefore,it can be concluded that this encryption method promotes the application expansion of blockchain in the field of sensitive data,and also provides a new direction for blockchain data sharing.
