    • 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.
    • 虚拟绑定系统确保不能避免用于保护数据不变性的WORM逻辑,有效地保证由可重写磁性硬盘组成的WORM存储系统的WORM属性。 要关闭可重写介质和WORM逻辑之间的安全漏洞,虚拟绑定安全地验证WORM逻辑控制器的合法性,然后才能授予WORM存储介质上的数据访问权限。 此外,系统在数据访问期间验证WORM逻辑控制器的合法性。 即使WORM逻辑控制器和WORM存储介质可能是物理上分离的,这种方式实际上将WORM逻辑控制器和WORM存储介质绑定在一起。
