| Abstract(in English) | The paper shows that genus two hyperelliptic curve cryptosystems over even degree finite fields come under Weil descent attack. Given a hyperelliptic curve of genus two over an even degree finite field, we construct an algebraic curve of genus eight over the subfield of the half degree, using the technique of Weil descent. We reduce DLP(Discrete Logarithm Problem) on the hyperelliptic curve to DLP on the new curve, and apply Gaudry variant against the Cab model of the curve. |
