Title	Cyber Security (CYBER); Quantum-Safe Cryptography (QSC); Secure Implementation Guidance for Key Encapsulation Mechanisms and Digital Signature Schemes; Part 2: ML-KEM ML-KEM Implementation Guidance
Scope and Field of Application	This work item is the second part in a series of quantum-safe implementation guidance documents. It is intended to provide developers with guidance to aid the secure implementation of the quantum-safe key encapsulation mechanism ML-KEM as specified by NIST FIPS 203. This will highlight some potential ML-KEM implementation hazards; identify some side-channel and fault attack issues specific to ML-KEM; consider some testing and formal verification aspects relevant to ML-KEM; and briefly discuss the secure usage of ML-KEM.
