Abstract: Taking advantage of the characteristics of bilinear pairings, an identity-based convertible limited verifier signature scheme is proposed. The scheme has the advantages of identity-based cryptosystem,and can resolve the conflict between authenticity and privacy in the digital signature. Security analysis of the proposed scheme shows that it satisfies non-transferability and unforgeability.

Key words: convertible limited verifier signature, identity-based, bilinear pairings
