New blind signature scheme based on hyperelliptic curve
Based on the analysis of hyperelliptic curve cryptography and design principle of blind signature, a novel blind signature scheme based on hyperelliptic curve cryptography is proposed by transplanting a proxy signature arithmetic into hyperelliptic curve cryptograph. Then security of the new scheme is analyzed. Cryptanalysis shows that it satisfies unforgeability, undenyability, non-trail, blindness and other security requirements of blind signature. By introducing hyperelliptic curve cryptography this scheme's capability of anti-attacking is improved evidently comparing with existing blind signature schemes based on other public key cryptography.
