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.

Main Features

  • Written entirely in the Java™ language
  • Compliant with ANSI X9.62-2005 (and legacy support for ANSI X9.62-1998), ANSI X9.63, IEEE P1363a, FIPS 186-4, SEC1 v2.0, SEC2 v2.0, RFC 5639 and ANSSI
  • ECDSA with SHA-1/SHA-2 support according to ANSI X9.62-2005 and BSI TR 03111 v1.11
  • RFC6979 support for ECDSA
  • EdDSA width Curve25519 and Curve448
  • Fast finite field arithmetic in prime fields
  • Fast finite field arithmetic in binary fields. In binary fields we only use polynomial base representation. This is mainly because of the patent situation, but there is no reason to use Gaussian normal bases.
  • Support for elliptic curve arithmetic with affine and several types of projective coordinates (Extended Jacobian, Jacobian, Lopez-Dahab, …)
  • Comprehensive domain parameter factory (see list of supported parameters)
  • JCE/JCA integration of ECDSA, ECDH (with and without cofactor multiplication, also for X25519/X448), ECIES, EdDSA and ECMQV (optional)
  • ASN.1 encoding of signatures, public and private keys
  • Support for point compression
  • Provides interfaces to IAIK-CMS and IAIK iSaSiLk libraries
  • Optional arithmetic speed-ups enhance performance (Koblitz curves, various optimized scalar multipliers, …). These are delivered with the add-on due to the vague patent situation.
  • Optional (basic) protection against (remote) timing side-channels
  • Asymmetric pairing (optimal Ate pairing) over Barreto-Naehrig curves (ranging from 160-bit to 638-bit curves)
