RELIC is a modern research-oriented 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.
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
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)
- Pairing delegation protocols with public and private inputs
- Batch pairing delegation protocols with public inputs
Instructions for building the library can be found in the Wiki.
For the pairing delegation protocols, look for the corresponding entries in the output of the test_cp testing binary, and entries with prefix cp_amore_* (1) (for the sequential version), cp_amore_* (AGGS) (for the batch version) in the output of the bench_cp benchmarking binary. You can change the parameter AGGS in the source code to adjust the number of pairings.

RELIC is at best 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. Side-channel and fault injection attacks are not considered in particular, unless it is explicitly noted. Use at your own risk.
