THRESHOLD ANONYMOUS AUTHENTICATION SCHEME WITHOUT TRUSTED CENTER
摘要
Abstract
Among the present anonymous authentication schemes, most of them existed in a trusted center and the anonymous controllability is optional. To solve these two problems, a new threshold anonymous authentication scheme based on the intractability of the discrete logarithm is presented. Because the proposed scheme doesn’t have a trusted party, it can prevent the trusted party from active or authoritative cheating. With the help of the method of group signature, the prover identity can be authenticated. On the basis of secure multi-party computation protocol, the prover identity can carry out the threshold anonymous tracking. The authenticator is anonymous, the prover is the traceable and the identity can’t be simulated, all of which can make the scheme well satisfy the security of anonymous authentication.关键词
