• Proxy re-signature is greatly concerned by researchers recently. It is a very useful tool for sharing web certificates, forming weak group signatures, and authenticating a network path. In this paper, we propose the first certificateless proxy re-signature scheme. Based on certificateless public cryptosystem, the scheme solves the using of certificate in certificate-based scheme and removes key escrow in ID-based scheme. Analysis shows that the proposed scheme can satisfy the required properties of proxy re-signature, and it can avoid public key replacement attack and malicious KGC attack.
