Abstract :
The paper proposes a provably-secure certificateless proxy re-signature scheme. Based certificateless public cryptosystem, it 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 a proxy re-signature, and it avoids public key replacement attack and malicious KGC attack. The scheme provides stronger security.
