| 摘要 | In one aspect, a method includes assigning a base key to a storage array, assigning a volume auxiliary key to each volume in the storage array, for each volume in the storage array that is encrypted, encrypting every block of a backend using the base key and one of a full hash auxiliary key or a short hash handle auxiliary key and for each volume in the storage array that is encrypted, encrypting an address-to-hash table of a volume using the base key and the volume auxiliary key. | ||

| 主权项 | 1. A method comprising: assigning a base key to a storage array; assigning a volume auxiliary key to each volume in the storage array; for each volume in the storage array that is encrypted, encrypting, using a processor, every block of a backend using the base key and one of a full hash auxiliary key or a short hash handle auxiliary key; and for each volume in the storage array that is encrypted, encrypting, using the processor, an address-to-hash table of a volume using the base key and the volume auxiliary key. | ||
