A New Method for Decomposition in the Jacobian of Small Genus Hyperelliptic Curves
Discrete Log Index calculus Hyperelliptic curve
2016/1/6
Decomposing a divisor over a suitable factor basis in the Jacobian of a hyperelliptic
curve is a crucial step in an index calculus algorithm for the discrete log problem in the
Jacobian. For small g...
A Simple Method for Obtaining Relations Among Factor Basis Elements for Special Hyperelliptic Curves
hyperelliptic curves index calculus algorithm Nagao’s decomposition
2016/1/3
Nagao had proposed a decomposition method for divisors of hyperelliptic curves defined over a field \rFqn with n≥2. Joux and Vitse had later proposed a variant which provided relations among the facto...
