Abstract:
1. A machine implemented method for calibrating a key life cycle with a data retention period, the method comprising the steps of: receiving, by a computer, the data retention period; using, by the computer, the received data retention period as a factor in selecting a key from a plurality of keys each having a preconfigured key life cycle, such that the key life cycle of the selected key is calibrated to the data retention period; wherein the key life cycle comprises a preconfigured length of time encryption is allowed, a preconfigured length of time decryption is allowed, a preconfigured length of time after encryption and decryption are allowed but the key still exists, and a preconfigured length of time until the key is purged; wherein the length of time encryption is allowed is not equal to the length of time decryption is allowed; and utilizing, by the computer, the selected key in encryption operations concerning corresponding data.
