Use of FrodoKEM in the Cryptographic Message Syntax

FrodoKEM is a quantum-resistant key encapsulation mechanism (KEM) based on the standard Learning With Errors (LWE) problem. It is one of three KEMs in the process of ISO standardization. This document specifies the conventions for using eight variants of FrodoKEM in the Cryptographic Message Syntax (CMS), by employing the KEMRecipientInfo structure defined in "Use of Key Encapsulation Mechanism (KEM) Algorithms in the Cryptographic Message Syntax (CMS)" [RFC9629]. These eight variants of FrodoKEM are (e)FrodoKEM-976-AES and (e)FrodoKEM-976-SHAKE for security level 3, and (e)FrodoKEM-1344-AES and (e)FrodoKEM-1344-SHAKE for security level 5.
