Kyber is a Key Encapsulation Mechanism (KEM) based on the Module Learning with Errors (MLWE) problem. It is an example of lattice-based cryptography and is part of the Crystals family together with the signature scheme Dilithium. It was selected for standardisation as part of the NIST post-quantum cryptography process in 2022. The standard is in progress.

Kyber is a Key Encapsulation Mechanism (KEM) based on the Module Learning with Errors (MLWE) problem. It is an example of lattice-based cryptography and is part of the Crystals family together with the signature scheme Dilithium. It was selected for standardisation as part of the NIST post-quantum cryptography process in 2022. The standard is in progress. It currently has three levels of parameterisation: Kyber512, Kyber 768 and Kyber1024 that are intended to meet the same levels of security as AES128, AES192 and AES256 respectively.
