Web• A cryptoperiod is the time span during which a particular cryptographic key can be used for its defined purpose. Considerations for defining the cryptoperiod include, but are not limited to, the strength of the underlying algorithm, size or length of the key, risk of key compromise, and the sensitivity of the data being encrypted. WebThere are many factors that determine an appropriate duration of the cryptoperiod, such as threat and risk model, encryption strength and risk of compromise. We recommend using a cryptoperiod of 1 year for data storage keys, which is consistent with current NIST recommendations (full publication, short version).
