Abstract :
This paper proposed a new certificateless self-identifiable ring signature scheme. It was constructed under certificateless mode, so it eliminates the need of certificates in the Public Key Infrastructure and solves the inherent key escrow problem in the identity-based cryptography. And it has three important properties: unconditional anonymity, self-identifiability, existential unforgeability against adaptive message and identity attacks under CDHP assumption. Moreover, it has shorter length, more efficiency and security than those of its primitive.
