Abstract: This paper proposes an efficient identity-based blind signature scheme based on identity-based public key cryptography by adopting blind signature scheme.By analyzing the scheme,it concludes that the scheme has unforgeability,blindness,untraceability.Compared with other schemes,the new scheme has lower computation complexity and better computational efficiency.

Key words: identity-based public key cryptography, blind signature, unforgeability, untraceability
