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 NSF-BSF Grant 2018640; the Israel Science Foundation (grant No. 3380/19); the BIU Center for Research in Applied Cryptography and Cyber Security, and the Center for Cyber Law and Policy at the University of Haifa, both in conjunction with the Israel National Cyber Bureau in the Prime Minister’s Office. Paulo L. 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). Tim Güneysu was partially supported by Intel (http://www.icri-cars.org). We thank Danilo Gligoroski and Ray Perlner for their comments in the NIST mailing list. We thank Andrew H. Reinders for his comments on the preliminary CCA version of BIKE. The logo presented in the cover page was designed by Szilard Nagy. The reference code was developed by Rafael Misoczki, Nir Drucker, Shay Gueron, Tim Güneysu, Tobias Oder and Slim Bettaieb. The hardware implementation was developed by Jan Richter-Brockmann and Tim Güneysu.
