ID-based cryptography is an important cryptographic system. Recently, by combining RSA and Fiat-Shamir identity authentication scheme, an ID-based one-off Blind public key was proposed to protect user's privacy in, and the authors claimed that the scheme had anonymity and unforgeability. In this paper, we give security analysis to the scheme of, and show this scheme has linkability and universal forgery...
In this paper, a new trusted platform module (TPM) anonymous authentication scheme is presented, by adding a ring administrator the members of the ring can be ensured that they are the legitimacy TPMs, the safety of the scheme is based on the DDH assumption and strong one-way function, it has shorter public parameters and it is be suitable for engineering.
