ABSTRACT:
When data is encrypted and stored for a long time, encryption key(s) and/or algorithm(s) should be updated so as not to be compromised due to malicious attack. To that end, stored encrypted data is converted in the storage system with new set of cryptographic criteria. During this process, read and write requests can be serviced.
