Abstract
A method for sending encrypted data in response to a request for an I/O operation. The method includes the steps of requesting a data encryption key, the request including one or more identifiers unique to the I/O operation; receiving a data encryption key attached with a first key use fingerprint, independently generating a second key use fingerprint in response to the one or more identifiers; comparing the first and the second key use fingerprints; and if the first key use fingerprint matches the second key use fingerprint, using the data encryption key to encrypt the data to be sent. In one embodiment, the one or more identifiers include at least one of a target identifier, a LUN identifier, and a LBA range identifier.
