Title:
I want to ride my BICYCL: BICYCL Implements CryptographY in CLass groups
Authors: Cyril Bouvier, Guilhem Castagnos, Laurent Imbert, Fabien Laguillaumie
Abstract:We introduce BICYCL an Open Source C++ library that implements arithmetic in the ideal class groups of imaginary quadratic fields, together with a set of cryptographic primitives based on class groups. It is available at crypto / 🚴♀️ BICYCL Implements CryptographY in CLass groups · GitLab under GNU General Public License version 3 or any later version. BICYCL provides significant speed-ups on the implementation of the arithmetic of class groups. Concerning cryptographic applications, BICYCL is orders of magnitude faster than any previous pilot implementation of the CL linearly encryption scheme, making it faster than Paillier’s encryption scheme at any security level. Linearly homomorphic encryption is the core of many multi-party computation protocols, sometimes involving a huge number of encryptions and homomorphic evaluations: class group-based protocols become the best solution in terms of bandwidth and computational efficiency to rely upon.
