Blind signcryption scheme based on hyper elliptic curves cryptosystem

In modern cryptography, the Discrete Logarithm Problem (DLP) plays a vital role, but a classical computer cannot efficiently solve it. Nowadays, the Hyper Elliptic Curve Discrete Logarithm Problem (HECDLP) of Genus two (G(2)) widely used in industry and also a research field of hot interest. This paper presents a novel blind signcryption scheme based on Hyper Elliptic Curves having properties of confidentiality, integrity, authenticity, non-repudiation, unforgeability, un-traceability, and message and original sender unlink-ability. The efficiency of our scheme is 76.85% and 80.95% in terms of communication cost w.r.t minor and major operations respectively. Also, the efficiency of our scheme 33.33% and 50% in terms of computation cost w.r.t minor and major operations. Our proposed scheme more suitable for emerging resource constraints environment like mobile commerce and digital democracy.
