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 (and preliminary ternary field arithmetic);
• Elliptic curves over prime and binary fields (NIST curves and pairing-friendly curves);
• Bilinear maps (Tate pairing over supersingular binary curves and optimal pairings over BN curves) and related extension fields;
• Cryptographic protocols (RSA, Rabin, ECDSA, ECMQV, ECSS (Schnorr), Sakai-Ohgishi-Kasahara ID-based authenticated key agreement, Boneh-Lynn-Schacham and Boneh-Boyen short signatures).

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.
