BTQ’s Preon, a Unique Quantum-Secure Signature Technology, Selected by NIST as Candidate for the Post-Quantum Cryptography Standardization Process

BTQ's Preon, a Unique Quantum-Secure Signature Technology, Selected by NIST as Candidate for the Post-Quantum Cryptography Standardization Process

BTQ Technologies Corp., a global quantum technology company focused on securing mission-critical networks, is proud to announce the National Institute of Standards and Technology (NIST) has selected BTQ’s post-quantum cryptography scheme, Preon, in the first round for consideration in their Post-Quantum Cryptography (PQC) standardization process.

This announcement comes amidst the fourth round of the ongoing PQC standardization process, wherein several Key Encapsulation Mechanisms (KEMs) including BIKE, Classic McEliece, and HQC are still being evaluated.

Since December 2016NIST has been engaged in a public process to select quantum-resistant public-key cryptographic algorithms for standardization, to combat the threats posed by the rapid advancement of quantum computing.Thus far, several algorithms have been standardized, including public-key encapsulation mechanism (KEM) CRYSTALS-KYBER and digital signatures CRYSTALS-Dilithium, FALCON, and SPHINCS+.With the exception of SPHINCS+, all these selected schemes are based on the computational hardness of problems involving structured lattices.

Preon is a post-quantum signature scheme, resilient against classical and quantum attacks. It operates based on a general proving system requiring minimal assumptions. This system is essentially a protocol that enables a verifier to be convinced of a prover’s secret knowledge, serving as a foundation for signature schemes.

Preon‘s distinctive features include a small key size, requiring only tens of bytes for both secret and public keys, which is significantly less compared to other signature schemes.Its key generation process is quick, employing one or two AES encryptions supported by modern computer hardware.The system assumes only the need for a collision-resistant hash function, enhancing security with fewer points of failure.It also offers flexible functionality, supporting various features like selective-reveal or threshold signature due to its construction based on a zero-knowledge proof.

Preon‘s selection in the PQC standardization process underscores the depth of our innovative work.Our dedicated team of researchers has created a highly efficient and secure cryptographic scheme.Preon‘s compact key size, fast generation, and flexible functionality provide a powerful tool against potential quantum threats, reinforcing our commitment to safeguarding digital infrastructures worldwide.” – Olivier Roussy Newton, CEO of BTQ
