Abstract:
One example method includes continuously performing key related operations. Each data set in a storage system is encrypted with a different key. New keys are repeatedly introduced and new data is encrypted only with the newest or latest key. Data being rekeyed is re-encrypted with the latest key. By repeatedly introducing new keys and rekeying data sets associated with older keys, the overall key age of the system can be kept low and the data is less susceptible to being compromised.
