Destruction: Complete and irreversible removal of keys when they are no longer needed. Unlike specifying exact algorithms, this publication focuses on the operational processes required to ensure keys remain secure from creation to destruction.
NIST SP 800-57 Physical Security Level 4 Requirements
Usage: Employing keys for their intended cryptographic operations, such as encryption or signing. These phases ensure that cryptographic materials are handled consistently and securely from the moment they are needed until they are no longer required.
Organizations should view this document as a foundational text for developing internal key management policies and procedures. Revocation and Deactivation: Temporarily disabling keys that are no longer trusted but might be needed later.
NIST SP 800-57 Physical Security Level 4 Requirements
Understanding the Purpose and Scope of NIST SP 800-57 The primary objective of NIST SP 800-57 is to standardize the way organizations handle cryptographic keys throughout their entire lifecycle. Key Management Lifecycle Overview NIST SP 800-57 structures key management into a logical lifecycle consisting of several distinct phases.
