| 摘 要： | 针对云服务提供商的可信状态和云环境数据服务的安全需求，提出了云环境数据服务的可信重加密安全模型，即在云环境下的数据安全需要云服务提供商满足一定的可信程度，再结合有效的重加密算法才能得以保证。通过对重加密模型进行安全分析，并用密码算法对重加密模型进行验证，得到实现重加密算法的约束条件，同时提出可信评价模型，对云服务提供商的可信状态进行动态评价，为建立云环境数据服务的可信安全提供理论基础和实现依据。

| 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. |
