%X In order to deal with the key exposure problem, this paper proposed a forward secure certificateless proxy signature scheme. This new scheme was forward secure by updating secret key frequently. When the proxy signature secret key was stolen, the attacker could not forge the former proxy signature. And then reduced the loss, which caused by the key exposure to a great extent. Based certificateless public cryptosystem, it also overcame the problem of the certificate management in the certificate-based public key cryptosystem and the inherent key escrow problem in the identity-based public key cryptosystem.
