Keeper Security Integrates Kyber to Provide Quantum-Resistant Identity Protection
Summary
Keeper Security has integrated the Kyber key encapsulation mechanism into its platform, enhancing protection against potential quantum computing threats. This lattice-based cryptography standard, endorsed by NIST, aims to secure identities against the evolving capabilities of quantum machines.
Key Insights
What is Kyber and why is it quantum-resistant?
Kyber is an IND-CCA2-secure key encapsulation mechanism (KEM) based on the hardness of solving the learning-with-errors (LWE) problem over module lattices, a lattice-based cryptography standard endorsed by NIST as ML-KEM. It resists quantum attacks because lattice problems are believed to remain computationally hard even for quantum computers, unlike traditional public-key cryptography vulnerable to algorithms like Shor's.
What is a Key Encapsulation Mechanism (KEM)?
A KEM is a cryptographic primitive that securely transports a symmetric shared secret key using public-key operations, involving key generation, encapsulation (producing a ciphertext and shared secret from the public key), and decapsulation (recovering the secret from the ciphertext using the private key). It provides strong security guarantees against both classical and quantum adversaries, essential for protocols like TLS.
