Trusted secure model for data services in cloud computing

Abstract

For trusted status of cloud service provider (CSP) and security requirements for data services in cloud computing,the trusted re-encryption secure model (TRSM) for cloud data services was proposed.Only with a certain trusted degree in CSP,cloud data security can be ensured by taking effective re-encryption schemes.The re-encryption secure model is verified by the classical cryptographic algorithms and analyzed by random oracles.Thus,the basic requirements of realizing re-encryption algorithm are got.Moreover,trusted evaluation model is proposed and used to dynamically evaluate CSP’s trusted status,provides theoretical basis and realization for establishment of trusted secure data services in cloud computing.
