Understanding Post-Quantum Cryptography
The Quantum Threat
Quantum computers pose a significant threat to many of today's cryptographic systems. Algorithms like RSA and ECC, which secure much of our digital infrastructure, could be broken by sufficiently powerful quantum computers using Shor's algorithm.
This vulnerability exists because these traditional algorithms rely on mathematical problems (like integer factorization) that quantum computers can solve efficiently.
Dilithium's Approach
Dilithium is based on lattice problems, specifically the Module Learning With Errors (M-LWE) and Module Short Integer Solution (M-SIS) problems, which are believed to be resistant to quantum attacks.
The "3" in Dilithium3 refers to the security level, which offers approximately 128 bits of security against quantum attacks—a strong level of protection for most applications.
