This standard specifies the four phases of key management as follows:
- Pre-operational phase: The keying material is not yet available for normal cryptographic operations. This phase has key preparation, key generation, and key distribution functions. - Operational phase: The keying material is available and in normal use. Keys are in the active state. This phase has key protection, key continuity, and key change functions. - Post-operational phase: The keying material is no longer in normal use, but access to the keying material is possible. This phase has key hold, and key revocation functions. - Destroyed phase: The keying material is no longer available. All records may have been destroyed. This phase contains no explicit functions. - The requirements for audit and trace functions are additionally defined for overall phases. |
