Abstract
Methods and systems are provided for verifying use of encryption keys. A request for verification information may be sent by a network element (e.g., server), with the request comprising combination of one or more identifiers, the combination associated with a particular I/O operation. The request may be sent to another element, which may be a centralized encryption management element (e.g., management server). In response to the request, key use verification information generated for the particular I/O operation may be received, and may be used thereafter in validating a corresponding encryption key, which may be used during data encryption or decryption, based on the received key use verification information and locally generated verification information associated with the particular I/O operation. The one or more identifiers include at least one of a target identifier, a LUN identifier, and a LBA range identifier.
