Certificateless Ring Signcryption Scheme from Pairings
摘要
Signcryption is a useful primitive which simultaneously provides the functions of encryption and signature. Certificateless cryptography not only eliminates the key escrow property, but also removes certificates. In a ring signcryption scheme, an entity can anonymously signcrypt a message on behalf of ring members including himself. In this paper, a new certificateless ring signcryption (CLRSC) scheme is proposed, and it is proved to be secure in the random oracle model. In the scheme, it requires only one bilinear pairing operation in signcryption, and three bilinear pairing operations in unsigncryption. To the best of our knowledge, our scheme is more efficient than previous ones in computation.
