Abstract: For the special requirements of digital signature about the embedded products with limited computing power and storage capacity, this paper analyzes the Jacobian discrete logarithm problem about hyperelliptic curve, and proposes a new sequential blind multisignature scheme based on hyperelliptic curves. The scheme meets the characteristics of sequential multisignature and blind signature at the same time, and its correctness, safety and efficiency are analyzed. The scheme can be widely used in digital signature fields.

Key words: hyperelliptic curve, reduced divisors, Jacobian group, sequential multisignature, blind signature
