中文摘要: 私有云作为云计算的一种重要部署模式,近年来得到了广泛的应用。目前协同安全问题已成为制约私有云进一步应用和发展的重要因素,而数据保护问题是私有云间协同安全中最基础的问题。目前在私有云间协同安全的数据保护研究领域还存在大量亟需解决的研究问题。鉴于此,本项目将针对私有云间协同安全中的如下数据保护关键问题展开研究:(1)研究如何利用自适应攻陷模型下无需双线性配对的条件代理数据重加密来解决私有云间的协同安全数据交换问题;(2)研究如何实现私有云间具有细粒度控制能力的协同安全数据访问控制;(3)研究如何利用同态数据隐私保护机制来实现私有云间协同用户数据隐私的保护问题。本项目将重研究通过可信第三方、单点访问和数据映射访问、以及条件代理重加密等技术来解决上述问题。本项目的研究成果将能促进私有云部署模式的进一步广泛应用,也将为解决公有云和混合云等其他云计算模式的安全问题提供参考价值。

英文摘要: As an important deployment model in cloud computing, private cloud has been widely used in recent years. Nowadays, collaboration security has become an import fact that hinders the further application and development of private cloud, and the data protection problem is the most important problem in collaboration security. Up to now, in the research field of data protection of collaboration security, there still exists a lot of important problems needed to be resolved. In view of this, we shall study the following key problems in the data protection of collaboration security: (1) how to resolve the data exchange problem for collaboration security, by using the conditional proxy re-encryption without bilinear pairings in the adaptive corruption model; (2) how to realize the fine-grained data access control for collaboration security in private cloud; (3) how to realize the data privacy protection for collaboration users in private cloud, via the homormorphic data privacy protection mechanism. This project will concentrate on the resolve of the above problem via trust third party, single point of access and data mapping access, and conditional proxy re-encryption mechanism. The research result in this project not only benefits the further wide application of the private cloud deployment model, and also can be refer
