What Module-Lattice-Based Key-Encapsulation Mechanism Standard requires
This standard specifies a key-encapsulation mechanism (KEM) called ML-KEM, which is a set of algorithms that can be used by two parties to establish a shared secret key over a public channel. The security of ML-KEM is related to the computational difficulty of the Module Learning with Errors problem, and it is presently believed to be secure, even against adversaries who possess a quantum computer. The standard specifies three parameter sets, ML-KEM-512, ML-KEM-768, and ML-KEM-1024, which offer different trade-offs in security strength versus performance. All three are approved to protect sensitive, non-classified communication systems of the U.S. Federal Government. This standard applies to information systems used or operated by federal agencies or by a contractor of an agency on behalf of an agency, but not to national security systems. It shall be used wherever the establishment of a shared secret key is required for federal applications, including for use with symmetric-key cryptographic algorithms. The core obligation is for implementations to conform to the specified algorithms and employ other approved cryptographic functions. Conforming implementations may replace the given set of steps with any mathematically equivalent set of steps, but must not use the component public-key encryption scheme (K-PKE) as a stand-alone scheme.
