Software Implementation of Genus-2 Hyperelliptic Curve Cryptosystems Over Prime Fields

Vladislav Kovtun, Jan Pelzl and Alexandr Kuznetsov

Abstract: This paper describes the system parameters and software implementation of a HECDSA cryptosystem based on genus-2 hyperelliptic curves over prime fields. We show how to reduce the computational complexity for special cases and compare the given cryptosystem with the well-known ECDSA cryptosystem based on elliptic curves.
