摘要： An online key stored by a remote service is generated or otherwise obtained, and a storage media (as it applies to the storage of data on a physical or virtual storage media) master key for encrypting and decrypting a physical or virtual storage media or encrypting and decrypting one or more storage media encryption keys that are used to encrypt a physical or virtual storage media is encrypted based at least in part on the online key. A key protector for the storage media is stored, the key protector including the encrypted master key. The key protector can be subsequently accessed, and the online key obtained from the remote service. The master key is decrypted based on the online key, allowing the one or more storage media encryption keys that are used to decrypt the storage media to be decrypted.

The cryptographic keys that corresponds each of the plurality of atoms in the access control rule are requested. One or more cryptographic operations are then performed on data using one or more of the cryptographic keys.

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： To comply with a policy for a computing device indicating that data written by the computing device to the storage volume after activation of the policy be encrypted, a sector map is accessed. The sector map identifies one or more sectors of a storage volume and also identifies, for each of the one or more sectors of the storage volume, a signature of the content of the sector. In response to a request to read the content of a sector, the content of the sector is returned without decrypting the content if the sector is one of the one or more sectors and the signature of the content of the sector matches the signature of the sector identified in the sector map. Otherwise, the content of the sector is decrypted and the decrypted content is returned.

摘要： To comply with a policy for a computing device indicating that data written by the computing device to the storage volume after activation of the policy be encrypted, an encrypted chunks map is accessed. The encrypted chunks map identifies whether, for each chunk of sectors of a storage volume, the sectors in the chunk are unencrypted. In response to a request to write content to a sector, the encrypted chunks map is checked to determine whether a chunk that includes the sector is unencrypted. If the chunk that includes the sector is unencrypted, then the sectors in the chunk are encrypted, and the content is encrypted and written to the sector. If the chunk that includes the sector is encrypted or not in use, then the content is encrypted and written to the sector.

摘要： Techniques for providing revocation information for revocable items are described. In implementations, a revocation service is employed to manage revocation information for various revocable items. For example, the revocation service can maintain a revoked list that includes revoked revocable items, such as revoked digital certificates, revoked files (e.g., files that are considered to the unsafe), unsafe network resources (e.g., a website that is determined to be unsafe), and so on. In implementations, the revocation service can communicate a revoked list to a client device to enable the client device to maintain an updated list of revocation information.
