IMPORTANT: RELIC has moved to GitHub

RELIC is a modern cryptographic meta-toolkit with emphasis on efficiency and flexibility. RELIC can be used to build efficient and usable cryptographic toolkits tailored for specific security levels and algorithmic choices.

Goals

RELIC is an ongoing project and features will be added on demand. The focus is to provide:

Ease of portability and inclusion of architecture-dependent code
Simple experimentation with alternative implementations
Tests and benchmarks for every implemented function
Flexible configuration
Maximum efficiency

Algorithms

RELIC implements to date:

Multiple-precision integer arithmetic
Prime and Binary field arithmetic
Elliptic curves over prime and binary fields (NIST curves and pairing-friendly curves)
Bilinear maps and related extension fields
Cryptographic protocols (RSA, Rabin, ECDSA, ECMQV, ECSS (Schnorr), ECIES, Sakai-Ohgishi-Kasahara ID-based authenticated key agreement, Boneh-Lynn-Schacham and Boneh-Boyen short signatures, Paillier and Benaloh homomorphic encryption systems)

RELIC is being used as the main cryptography implementation of the TinyPBC project. Support was included in version 0.1.1. Build instructions for MICAz motes suitable for TinyPBC deployments can be found in the Wiki.

Downloading

Future releases will be made available in the Wiki.

Licensing

RELIC is released under an LGPL version 2.1-or-above license to encourage collaboration with other research groups and contributions from the industry.

Starting from version 0.3.3, static linking and changes in the configuration or build system are explicitly exempted from representing derived works. Please refer to files COPYING and COPYING.LESSER for additional details.

Disclaimer

RELIC is at most alpha-quality software. Implementations may not be correct or secure and may include patented algorithms. There are many configuration options which make the library horribly insecure. Backward API compatibility with early versions may not necessarily be maintained. Use at your own risk.
