Survey on Application of Searchable Attribute-based Encryption Technology Based on Blockchain
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 com-plexity,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.
