Abstract
Systems and methods for providing data integrity for stored data are disclosed. A method may include, in connection with the receipt of a read command at a storage resource, reading a data block from the storage resource, the data block including a data field, a data integrity field indicating the integrity the data field, and an encryption indicator field indicating whether the data block is encrypted with a current cryptographic key for the storage resource. The method may further include determining whether the data field is encrypted with the current cryptographic key based at least on the encryption indicator field. The method may additionally include returning at least a portion of the data block in reply to the read command in response to determining that the data field is encrypted with a cryptographic key other than the current cryptographic key.
