Abstract
A virtual binding system ensures that the WORM logic for protecting data immutability cannot be circumvented, effectively guaranteeing WORM property of a WORM storage system composed of rewritable magnetic hard disks. To close the security hole between the rewritable media and the WORM logic, virtual binding securely authenticates the legitimacy of a WORM logic controller before granting data access on a WORM storage media. Furthermore, the system verifies the legitimacy of the WORM logic controller during data access. This approach virtually binds together the WORM logic controller and the WORM storage media even though the WORM logic controller and the WORM storage media may be physically separate.
