Once operational, the quantum computer will sweep away all the principles on which cryptography is currently based. The National Institute of Standards and Technology (NIST) launched a call for papers in 2016 to find algorithms capable of withstanding it.
Of the four post-quantum resistant cryptographic algorithms selected by the NIST, Falcon is one of them, a model co-developed by Thales, IBM, NCC Group, Brown University and the University of Rennes 1. Falcon (acronym for "Fast Fourier lattice-based compact signatures over NTRU") was designed by Pierre-Alain Fouque (Professor at the Université de Rennes 1 and head of the Capsule research team at IRISA), Jeffrey Hoffstein, Paul Kirchner, Vadim Lyubashevsky, Thomas Pornin, Thomas Prest, Thomas Ricosset, Gregor Seiler, William Whyte and Zhenfei Zhang.
