Falcon algorithm - co-developed with Thales - selected by NIST as new post-quantum cryptography standard
The US Department of Commerce's National Institute of Standards and Technology (NIST) has selected the Falcon algorithm for digital signatures.
Co-developed to become the standard for post-quantum cryptography, it is capable of withstanding attacks from future, extremely powerful quantum computers.
Selected for its high level of security and remarkable spectral efficiency, Falcon will be integrated into NIST's post-quantum cryptography standards, the definition of which should be finalised within two years.
The selection of Falcon, after five years of worldwide competition, demonstrates Thales' leadership in cybersecurity, advanced technologies and research.
In the international competition launched in 2017 by NIST to establish future post-quantum cryptography standards for digital signatures and public key encryption, in which 82 applicants from 25 countries participated, the Falcon algorithm was selected for its extremely high level of security and very high spectral efficiency.
Falcon was co-developed by Thales with academic and industrial partners from France (Université Rennes 1, PQShield SAS), Switzerland (IBM), Canada (NCC Group) and the United States (Brown University, Qualcomm). It has been selected by NIST along with two other algorithms as the standard for digital signatures, while a fourth algorithm has been selected as the standard for public key encryption. Thales is the only high-tech group active in the defence, aerospace and digital identity markets to have participated in the competition.
Post-quantum cryptography will enable conventional computers to withstand attacks from extremely powerful quantum computers, which many experts expect to appear within a few years. Quantum machines will give computers so much computing power that they will be able to break current cryptographic algorithms in a matter of seconds.
This "quantum leap" in computing power could pave the way for a "cryptographic apocalypse" and pose an extremely serious threat to the security of digital systems used by citizens and organisations around the world on a daily basis, such as critical information systems, online banking, payment cards, e-commerce, electronic signature procedures or online voting.A hacker with a quantum computer, for example, could easily gain access to confidential data, impersonate someone or falsify legal transactions and contracts. Similarly, a nation's security could be threatened if its critical communication systems were the target of a quantum attack.
What makes new algorithms, such as Falcon, quantum-proof are the mathematical problems on which they are based, which are some of the hardest to solve, even for a quantum computer.
Organisations wishing to protect their data in a 'zero trust' world need to adopt a robust quantum crypto-agility strategy. Thales' cyber solutions consulting teams have developed a post-quantum cyber architecture offering to help their customers prepare for the risk of cyber attacks from quantum computers. Thales also uses quantum-resistant algorithms in its Luna encryption network and HSM module.
"
Thales has been at the forefront of post-quantum cryptography research since 2013; the selection of the Falcon algorithm by NIST is recognition of the excellent co-development work and expertise of our encryption teams. We will continue our ongoing research in France and Europe to develop innovative post-quantum trust solutions, without sacrificing any performance. We are already supporting our customers in their transition to a new generation of security solutions to avoid a future 'cryptographic apocalypse'," said Pierre-Yves Jolivet, Vice President, Cyber Defence Solutions at Thales.
