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。

关键词: 云数据服务, 重加密, 数据安全, 可信模型

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.

Key words: cloud data services, re-encryption scheme, data security, trusted model
