面向云隐私保护的5A问责制协议设计

5A accountability privacy protocol with privacy-preservingfor cloud computing

云计算的隐私保护是目前业界最为关注的问题。文中基于云计算参与者实际交互需求机制,在5A问责制的隐私建模研究基础上,从云运行实际机制和隐私问责保护实际需要出发,提炼、设计符合云隐私保护实际需求的问责制协议方案。在云租户与服务提供方之间、服务提供方之间以及云参与者与云系统之间进行协议的提炼和归纳,设计符合问责隐私保护实际需求的协议机制,使隐私问责制系统具有实用性和可行性。重点从云参与者的隐私需求描述、隐私服务承诺、网络行为审计、隐私暴露条件、违约认定和处罚方面进行协议设计,并基于协议测试仪Smart bit 6000C对问责制系统进行建模、测试与验证,测试结果验证了协议技术的正确性和可行性。

Currently,the privacy protection of cloud computing is the most important issue in the industry.Based on the actual interaction demand and the mechanism of cloud computing participants,and the actual operation mechanism of cloud operation and the actual needs of privacy accountability protection,this paper designs a protocol scheme meeting actual needs in 5A accountability system.Refining protocols from cloud participants,including cloud tenants,cloud service providers and the cloud system,the design of this paper can meet the actual needs of the accountability mechanism that realizes agreement privacy protection protocols,making the privacy accountability system have the practicability and the feasibility.The protocols are mainly focused on cloud user privacy requirement description,privacy guarantee of cloud computing system,network behavior auditing,privacy exposure condition,breach of contract recognition,and punishment.The simulation environment is constructed based on the tester Smart bit 6000C.The experimental results verify the efficiency and the feasibility of the designed protocol.
