摘要：An anonymous proxy signature is applied in the situation of a proxy signature that the proxy singer hopes to keep secret of his identity and when disputation is appearing, the verifier can reveal the real identity of the proxy signer with the help of the original signer. In this paper, we analyze Zhao et al.'s id-based anonymous proxy signature. We show that their scheme is not truly "ID-Based" and it is vulnerable to an attack similar to "Key Replacement Attack" in the certificateless signature. At last, we propose an enhanced ID-Based anonymous proxy signature scheme and analyze its security. ©2010 IEEE.
