Design of Privacy Preservation Authentication Protocol in Pervasive Environment
Shiwei Huo · Jisuanji gongcheng · 2012
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.
