Welcome to the BIKE Website

This website will be used by the BIKE team as its official communication media.

BIKE is a code-based key encapsulation suite based on QC-MDPC (Quasi-Cyclic Moderate Density Parity-Check) codes, which was submitted to the NIST standardization process on post-quantum cryptography. The BIKE suite consists of three variants: BIKE-1, BIKE-2 and BIKE-3. Each variant offers different performance trade-offs.

04/13/2018 - BIKE is presented at the 1st NIST PQC Conference (slides).
12/20/2017 - NIST accepts BIKE as a "complete and proper" submission.
11/30/2017 - BIKE is submitted to the NIST standardization process.

Shay Gueron, Tim Güneysu, Nicolas Sendrier and Jean-Pierre Tillich were supported in part by the Commission of the European Communities through the Horizon 2020 program under project number 645622 (PQCRYPTO). Shay Gueron was also partially supported by the Israel Science Foundation (grant No. 1018/16). Paulo S. L. M. Barreto was partially supported by Intel and FAPESP through the project "Efficient Post-Quantum Cryptography for Building Advanced Security Applications" (grant No. 2015/50520-6). We thank Danilo Gligoroski and Ray Perlner for their comments in the NIST mailing list. The BIKE logo was designed by Szilard Nagy, who kindly granted permission to use it for the BIKE submission (but should not be considered as part of the BIKE project itself or any of the BIKE implementations). The reference and optimized implementations were developed by Rafael Misoczki, Nir Druker, Shay Gueron, Tim Güneysu, Tobias Oder and Slim Bettaieb. The additional implementation was developed by Nir Druker and Shay Gueron.
