Efficient Computation of the Tate Pairing on Hyperelliptic Curves for Cryptosystems

YoungJu Choie and Jaemyung Kim and Eunjeong Lee

Abstract: In this paper, we suggest to use the curve $\curve, b=0 \mbox{ or } 1$ over $\Ftn$ for a secure and efficient pairing-based cryptosystems. For this curve, we develop efficient algorithms to compute the Tate pairing and give an implementation result of Tate paring on the curve $H_0$.

Category / Keywords: public-key cryptography / Tate pairing computation, hyperelliptic curve, identity-based encryption, implementation
