Blockchain-based result-traceable searchable encryption scheme

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.
