Welcome to the resource topic for 2004/030

Title:
Point Compression on Jacobians of Hyperelliptic Curves over \F_q.

Authors: 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.
