Traditional cloud storage systems do not adapt well to different application environment and does not guarantee the integrity and confidentiality of cloud data. In order to solve the problems brought by the hysteretic and density in the cloud storage system,A Searchable Re-encryption Storage Method (SReCSM) is proposed in this paper. The central idea of the SReCSM is to generate a re-encryption key and decrypte while the keyword matched. Simulation results show that SReCSM introduced in this paper has better security and reliability.
