Point Compression on Jacobians of Hyperelliptic Curves over $\F_q$.

Colin Stahlke

Abstract

Hyperelliptic curve cryptography recently received a lot of attention, especially for constrained environments. Since there space is critical, compression techniques are interesting. In this note we propose a new method which avoids factoring the first representing polynomial. In the case of genus two the cost for decompression is, essentially, computing two square roots in $\F_q$, the cost for compression is much less.
