  • Apparatus, system, and method for checking the health of encryption key managers
    Patent number: 8938400
    Abstract: An apparatus, system, and method are disclosed for checking the health of encryption key managers (EKM). An identification module identifies an EKM of a plurality of EKMs. A communication module establishes communication with the EKM. A request module requests an encryption key from the EKM. A verification module verifies that there is a valid encryption key path to the EKM. In one embodiment, the verification module validates that the EKM can exchange encryption keys with a tape drive. The verification module may also validate that the EKM can certify the authenticity of a tape drive.
