Imagine points arranged in a regular grid pattern extending in hundreds or thousands of dimensions. That's a lattice. Lattice-based cryptography creates security from hard problems about these high-dimensional lattices - finding the shortest vector, finding the closest vector, solving equations with small errors (Learning With Errors). Why do we care? Because these problems are believed to be hard even for quantum computers. Unlike factoring and discrete logarithms which Shor's algorithm cracks, lattice problems resist known quantum algorithms. Even better, they have worst-case to average-case security reductions - if you can break typical instances, you can break the hardest instances, which is rare in cryptography. The practical result: all of NIST's primary post-quantum standards use lattice cryptography. CRYSTALS-Kyber and CRYSTALS-Dilithium are lattice-based. Lattices also enable advanced features like fully homomorphic encryption where you can compute on encrypted data without decrypting it first.
The cryptographic community studied lattices for 20+ years before NIST selected them for post-quantum standards. They're not new or untested - they're extensively analyzed, with strong security proofs and efficient implementations. Lattice cryptography is the foundation of the post-quantum era.
When NIST says "migrate to post-quantum cryptography," they mean migrate to lattice cryptography (with some hash-based signatures as backup). Kyber for key exchange, Dilithium for signatures - both lattice-based. Understanding lattices isn't just academic - it's understanding the security foundation of the next 30 years of cryptography.
