Symmetric key-agreement key: a. Type Considerations: A symmetric key-agreement key may be used multiple times. Generally, the originator-usage period and the recipient-usage period are …
WebThe total cryptoperiod can be up to 5 years so you can have a 2 year OUP and a RUP which begin concurrently with the OUP and last the length of the OUP and an additional three years for a total of 5 years. WebA crypto-period depends on the usage frequency of a key. One digitally signed document per month requires one cryptoperiod; 5.6 billion requires a much shorter period! Carefully think about your Key Encryption Keys (KEKs). Every time you use KEK, you give a hint to a crypto-analytic. Change you KEKs appropriately.
