The IAIK ECCelerate™ library for the Java™ platform is based on Java 6 technology and offers easy to use elliptic curve cryptography protocols, like ECDSA, ECDH, ECIES and ECMQV (optional), compliant with current standards. As of version 3.0, it also provides support for asymmetric bilinear pairings using Barreto-Naehrig curves. Since version 5.0, ECCelerate™ supports EdDSA and DH based on X25519 and X448. ECCelerate™ is an add-on to the IAIK JCE provider (of version 5.51 or higher), which you have to download and install separately.
