摘要

Abstract

Aiming at the problem of search over encrypted data in mobile cloud storage,this paper proposed a searchable attribute based encryption scheme,and proved the security of the scheme under the standard model.This scheme hid the access structure to protect the sensitive information in the access policy.By assigning the search server,the search process didn't need a secure channel and could effectively resist keyward guessing attack.In the scheme,the length of users' key,keyword index and search credentials were fixed.The search algorithm required only twice computations of bilinear pairings.The performance analysis and simulation results show that the scheme can be applied to mobile cloud storage environment efficiently.
