    摘要： A key recovery request for a device is received at a key recovery service and a particular one-time recovery credential in a sequence of multiple one-time recovery credentials is identified. In the sequence of multiple one-time recovery credentials, previous one-time recovery credentials in the sequence are indeterminable given subsequent one-time recovery credentials in the sequence. A recovery key associated with the device is also identified. The particular one-time recovery credential in the sequence is generated based on the recovery key, and is returned in response to the key recovery request. The particular one-time recovery credential can then be used by the device to decrypt encrypted data stored on a storage media of the device.

    摘要： In accordance with one or more aspects, a key protector for a storage volume is created by generating an intermediate key and protecting, based at least in part on a public/private key pair, the intermediate key. A volume master key for encrypting and decrypting one or more volume encryption keys that are used to encrypt the storage volume can be encrypted in different manners, including being encrypted based at least in part on the intermediate key. A key protector for the storage volume is stored that includes both the encrypted volume master key and information indicating how to obtain the intermediate key. Subsequently, the key protector can be accessed and, based at least in part on a private key of the entity associated with the key protector, the intermediate key can be decrypted. The intermediate key can then be used to decrypt the volume master key.
