What is Post-Quantum Cryptography (PQC)?
Quantum computers operate on principles of quantum mechanics, enabling them to solve complex mathematical problems like integer factorization exponentially faster than classical computers. This renders traditional encryption algorithms (like RSA and ECC) completely vulnerable.
PQC relies on advanced mathematics, such as lattice-based cryptography, which remains mathematically intractable for both classical and quantum systems. By migrating to NIST approved PQC algorithms today, you ensure long term data confidentiality and "harvest now, decrypt later" protection.
