20100172491 | Computing Isogenies Between Genus-2 Curves for Cryptography - This cryptographic curve generation technique provides a faster way of constructing a genus 2 curve.

The technique computes a set of polynomials that define all isogenies. To do this, for a given root of an Igusa class polynomial over a finite field, the technique computes a value of a small modular function ƒ. To the value of this function ƒ, the technique applies an isogeny to find an isogenous ƒ-value. The technique then transforms the ƒ-value back into an Igusa value. Once the Igusa class polynomials are solved they can be used to generate a genus 2 curve which can be used in cryptographic applications. | 2010-07-08 |
