Quantum-Resistant Authentication using Lattice- Based Cryptography

As quantum computing gains traction, classical forms of encryption such as RSA and ECC may be rendered obsolete. To remain ahead, we must have more robust security measures—and that is where lattice-based cryptography steps in. This work examines how it is possible to use Kyber (for key exchange securely) and CRYSTALS-DILITHIUM (for digital signatures) in JavaScript, making quantum-resistant security accessible for web applications. We deconstruct major concepts, detail actual implementation techniques, and consider performance trade-offs, illustrating how developers can pre- empt their systems against the dangers of quantum.
