Abstract :
Bsaed on certificateless public cryptosystem and forward-secure, a forward-secure certificateless proxy blind signature scheme was proposed. This new scheme is forward-secure by updating secret key frequently. We can reduce the loss of the key exposure problem. And it also overcame the problem of certificate management in the certificate-based public key cryptosystem and the inherent key escrow problem in the identity-based public key cryptosystem.
