Anonymous attribute authentication scheme using self-blindable certificates
Shinsaku Kiyomoto, Toshiaki Tanaka · 2008
In this paper, we propose a perfectly anonymous attribute authentication scheme that is both unidentifiable and untraceable. The proposed scheme employs a self-blindable certificate that a user is able to change randomly; thus the certificate is modified for each authentication, and the authentication scheme is unidentifiable and untraceable. Furthermore, our scheme can revoke issued self-blindable certificates without leaks of confidential private information and check the revocation status without online access.
