The Cryptographic Cliff
Current RSA and Elliptic Curve encryption rely on the mathematical difficulty of factoring large integers. A sufficiently powerful quantum computer, using Shor's Algorithm, can solve this in minutes. This is why NIST is already standardizing Post-Quantum Cryptography (PQC).
Lattice-Based Cryptography
The leading candidates for PQC are lattice-based algorithms like Kyber and Dilithium. These rely on finding the shortest vector in a multi-dimensional lattice, a problem that is believed to be hard even for quantum computers.
