In compliance with CWA , Section 5. There must be re-authentication after log-out and the authentication data, where used, is unique and cannot be reused. Short term session keys are not categorized as Infrastructure keys. In terms of security requirements, ALL Signing Keys are long-term keys whose impact from exposure is high. Consequently, countermeasures for managing this risk are also high, both in number and in effect.

Infrastructure keys are also considered high risk but due to their distributed functionality and shorter lifespan they are a lower risk in comparison to signing keys.

Key Usage. This is the controlling of usage of generated keys within cryptographic algorithms to provide cryptographic services.

Key Change. Key change may be: Programmed - where a key is replaced by a newly generated key once it reaches the end of its operational life as determined by policy Non-Programmed — where a key is replaced by a newly generated key if it has been compromised. When a key is compromised or when it reaches the end of its operational life it may be destroyed to prevent any further use of the key.

After Key Generation, the keys may be stored in secure environments and may be copied and backed up to meet operational requirements. These backed up keys may need to be recovered when for example the existing key is inadvertently destroyed. Blog Account Site Map.
