Certificateless Group Oriented Signature Secure Against Key Replacement Attack
Abstract
Since Al-Riyami and Paterson presented certificateless cryptography, many certificateless schemes have been proposed for different purposes. In this paper, we present a certificateless group oriented signature scheme based on bilinear pairing. In our scheme, only the members in the same group with the signer can independently verify the signature. We prove the signature scheme is existential unforgeability under adaptive chosen message attack in random oracle model.
