public Class ECJPAKECurves

Class Inheritance

extends Object

java.lang.Object
org.bouncycastle.crypto.agreement.ecjpake.ECJPAKECurves

Imports

org.bouncycastle.asn1.nist.NISTNamedCurves, org.bouncycastle.asn1.x9.X9ECParameters, org.bouncycastle.math.ec.ECCurve

Standard pre-computed elliptic curves for use by EC J-PAKE. (J-PAKE can use pre-computed elliptic curves or prime order groups, same as DSA and Diffie-Hellman.)

This class contains some convenient constants for use as input for constructing ECJPAKEParticipants.

The prime order groups below are taken from NIST SP 800-186, "Recommendations for Discrete Logarithm-based Cryptography: Elliptic Curve Domain Parameters", published by NIST.
