Providing a virtual binding for a worm storage system on rewritable media
View Patent ↗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.
1. A system configured to provide a virtual binding for a write once read many (WORM) storage system on a rewritable medium, comprising:
a WORM logic controller and a WORM storage module of a security-enhanced storage enclosure;
the WORM storage module being configured to register the WORM logic controller on the WORM storage module;
a controller authenticator configured to authenticate the WORM logic controller using a public key;
a storage authenticator configured to authenticate the WORM storage module,
wherein the security-enhanced storage enclosure is configured to migrate by removing the public key from a storage user table and registering the security-enhanced storage enclosure at a new location, and the WORM logic controller is configured to migrate by removing the public key from the controller authenticator and registering the WORM logic controller at a new location,
wherein the WORM logic controller and the WORM storage module are configured to execute a command on the rewriteable medium in a secure manner.
