摘要:
The payload of a set of storage devices is encrypted using a payload key that is stored within the set of storage devices itself. However, the payload key is obtainable only if a user has access to n of the storage devices. A first set of keys can be distributed among a set of n storage devices, such that each key is usable to encrypt and/or decrypt a key stored on a different one of the n storage devices. The first set of keys is usable to encrypt portions of the information needed to regenerate another key (e.g., the payload key or a key used to encrypt the payload key). A different portion of the information needed to regenerate the other key is stored on each of the n storage devices. Accordingly, the other key cannot be obtained unless the user has access to all n storage devices.
