基于区块链的可搜索属性加密技术应用综述

Survey on Application of Searchable Attribute-based Encryption Technology Based on Blockchain

随着信息共享的蓬勃发展,数据隐私安全问题逐渐凸显,催生了区块链技术和可搜索属性加密技术的迅速发展。区块链作为一种去中心化、不可篡改的技术,保障了搜索数据的安全性和完整性,可搜索属性加密技术可以有效地防止非法用户的访问查询。然而随着数据规模和复杂性的增加,出现了检索效率低、查询结果验证复杂、属性权限分发困难等问题。首先,针对以上问题,分别总结了基于区块链的可搜索加密技术、基于区块链的属性加密技术以及基于区块链的可搜索属性加密技术应用的研究现状。其次,对三者之间的优势和侧重点进行了比较分析。最后,重点总结了基于区块链的可搜索属性加密技术在关键字检索、属性权限管理以及数据完整性验证方面的应用,以及所面临的问题和挑战。希望为实现更安全、高效、去中心化的数据存储与共享提供更加安全的技术应用支持。

With the vigorous development of information sharing,the problem of data privacy security has gradually become prominent,which has spawned the rapid development of blockchain technology and searchable attribute encryption technology.As a decentralized and immutable technology,blockchain ensures the security and integrity of search data,and searchable attribute encryption technology effectively prevents illegal users from accessing queries.However,with the increase of data size and complexity,there are some problems,such as low retrieval efficiency,complicated query result verification,and difficult distribution of attribute permissions.Firstly,in view of the above problems,the research status of the application of blockchain-based searchable encryption technology,blockchain-based attribute encryption technology and blockchain-based searchable attribute encryption technology is summarized respectively.Secondly,the advantages and emphases of these three are compared and analyzed.Finally,the paper focuses on the application of blockchain-based searchable attribute encryption technology in keyword retrieval,attribute permission management and data integrity verification,as well as the problems and challenges faced.It also hopes to provide more secure technical application support for more secure,efficient and decentralized data storage and sharing.
