普适计算的隐私保护协议

A Privacy Protocol for Pervasive Computing

改进了一个用于保护用户隐私的安全协议。该协议引入了服务发现者,用户并不直接与服务提供者进行通信,而是通过服务发现者来完成用户的需求。通过对协议的安全分析,可以看出:该协议保护了用户的隐私,也防止了用户被跟踪,并且减少了原有协议的计算量,更适合普适计算。该协议可以很好的保护用户的隐私,并且能够防止重放攻击。

In this paper, a secure protocol to protect user privacy is improved. In this protocol the users does not directly communicate with the service provider, instead, the user connects through the service discoverers to complete their needs. Through analysis of the security system in the protocol, it becomes clear that this protocol protects users＇ privacy, and prevents users from being tracked at the same time. The protocol reduces the computational complexity of the original protocol, and it is more suitable for ubiquitous computing. The protocol may very well protect users＇ privacy, and can also prevent replayed attack.
