Port-quantum cryptography (PQC) is a branch of cryptography designed to remain secure against attacks from quantum computers. While many symmetric encryption schemes and hash functions are already considered quantum-safe at sufficiently large key sizes, asymmetric algorithms widely used today are vulnerable to quantum attacks. Post-quantum algorithms, particularly those based on Lattice-based cryptography, are specifically designed to close this gap.
Polynom implements post-quantum algorithms submitted to and accepted by the National Institute of Standards and Technology (NIST) standardization process, as well as those recommended by the NSA's Commercial National Security Algorithm (CNSA) Suite.
It is worth noting that no cryptographic system can be guaranteed secure forever. Cryptography is continuously tested and analyzed, and security assumptions evolve over time as new research emerges.
