Patent Primary Examiner
A distributed database encrypts tables using table encryption keys protected by a client master encryption key. The client may revoke authorization to access the client master encryption key. Subsequent to a revocation of authority to access the client master encryption key, the distributed database generates interim snapshots of the table using the table encryption key. Also subsequent to the revocation, the distributed database generates a backup of the table using a backup encryption key protected by the client master encryption key.
