摘要

在可搜索加密方案中，无论是云端服务器还是用户，都可能存在欺骗行为。为了解决这种安全问题，给出公平性安全的定义，提出基于区块链的可搜索加密方案。通过第三方可信机构（trusted authority，TA）验证数据传输过程中数据的一致性，区块链记录完整验证结果以防止篡改，使所涉及的实体达成一致的安全共识，从而实现公平性安全。安全性与复杂性分析表明，该方案是可行的。当该方案与搜索结果可验证的可搜索加密方案相结合时，可优化成基于区块链的搜索结果可验证的可搜索加密方案，其安全性将得到进一步的提高。

Abstract

In a searchable encryption scheme

whether it is a cloud server or a user

it may be deceptive.In order to solve the security problem

the definition of fairness security was given and a new searchable encryption scheme based on blockchain was proposed.Through the third-party trusted authority to verify the consistency of data during data transmission

the complete verification results were recorded on the blockchain to prevent tampering

and it could make all the related entities to reach the consistent security consensus and achieve the fairness security.The security and complexity analysis show that the proposed searchable encryption scheme was feasible.If it is combined with a searchable encryption scheme with its searched results verifiable

the proposed scheme can be effectively improved to be a blockchain-based searchable encryption scheme with its searched results verifiable and its security will be more strengthened.
