摘要: 针对普适环境中的认证和隐私保护问题,运用哈希链和部分盲签名技术,提出一种新的隐私保护认证协议。该协议运用哈希链构造信任书,保证每个信任书只能使用一次,利用部分盲签名在信任书中嵌入用户访问次数,对用户的访问次数进行控制。在实现用户匿名访问和双向认证的同时,解决服务滥用和非授权访问问题。仿真结果表明,与同类协议相比,该协议具有更好的安全特性和较高的执行效率。

Abstract: Aiming at the problem of the authentication and privacy preservation in pervasive environment, a new privacy preservation authentication protocol is proposed based on hash chain and partially blind signature. The protocol uses hash chains to constructe credential access to guarantee every credential access only once, and uses partially blind signature to embed user credential access number to limite user access frequency. The anonymity access and the mutual authentication are achieved, while the abusing service and non-authorization are solved. Simulation result shows that compared with the available scheme, the proposed protocol has higher security and efficiency.

Key words: pervasive environment, authentication, privacy preservation, partially blind signature, hash chain, anonymity
