Abstract: As to the characteristics of multisignature and blind signature, this paper presents a new sequential blind multisignature scheme based on hyperelliptic curves, and its validity is proved. The signature structure is expanded, and some signature nodes are changed to broadcasting signature structure. A new broadcasting blind multisignature scheme is presented, and its correctness is proved. The safety and efficiency of the two schemes are analyzed.

Key words: hyperelliptic curve, reduced divisors, broadcasting, blind signature, multisignature
