Introduction

Hard geometry problems as the basis for security

Much of today's public-key cryptography relies on math problems that a large quantum computer could solve efficiently. Lattice-based cryptography builds on a different class of problems, finding short or close vectors in high-dimensional lattices, that are believed to be hard for both classical and quantum computers. It can support key establishment, digital signatures, and more advanced schemes, and lattice algorithms are among those selected by NIST for standardization. The trade-offs are larger keys and ciphertexts and careful implementation, which matter most for constrained devices.

Core components & key features

What lattice-based cryptography systems are made of

From the underlying math to the schemes and implementations that use it.

Hard lattice problems
Security rests on problems such as learning with errors that are believed hard even for quantum computers.
Key establishment
Key-encapsulation schemes that let two parties agree on a shared secret securely.
Digital signatures
Signature schemes that provide authentication and integrity with quantum-resistant security.
Standardized algorithms
NIST-selected lattice-based algorithms, such as ML-KEM and ML-DSA, that are becoming the common baseline.
Efficient implementation
Optimized software and hardware that manage speed, memory, and key and ciphertext sizes.
Advanced schemes
Lattices also support richer capabilities such as homomorphic encryption and other advanced protocols.
Challenges addressed

Limits of traditional cryptography in a quantum world

The threat is clear. The remaining work is in deploying the replacement at scale.

01
Quantum vulnerability of today's public-key schemes
Widely used methods based on factoring and discrete logarithms could be broken by a large quantum computer
02
Long-term data exposure
Data encrypted today can be recorded and decrypted later, so long-lived secrets need protection now
03
Larger keys, ciphertexts, and compute needs
Lattice schemes can need more bandwidth and memory, which is demanding for IoT and embedded devices
04
Migration and implementation risk
Moving large systems to new algorithms, while avoiding implementation flaws and side channels, takes planning and time
