cryptographic key management information

This phrase is compositional rather than a term of art. It is a descriptive noun phrase combining "cryptographic key management" (the discipline governing the lifecycle of cryptographic keys) with "information" (the data involved in or produced by that discipline). NIST SP 800-57 Part 1 frames this domain as covering cryptographic keying material together with "other cryptographic information" requiring protection, and the functions and issues involved in managing it — but the combined phrase "cryptographic key management information" is not defined as a standalone entry. NIST's CSRC describes the scope of its Cryptographic Key Management Systems publications as addressing "the policies, procedures, components and devices that are used to protect, manage and establish keys and associated information (metadata)" — using "associated information" or "metadata" rather than coining the longer phrase as a term. No authoritative source (NIST, ISO, AICPA, CIS, or a regulator) treats it as a defined vocabulary item with a fixed, bounded meaning.
