摘要： One embodiment of the present invention provides a system that can expire encrypted-data. During operation, the system receives an expiry-request that includes object-identifying information, which can be used to identify a set of database objects that contain the encrypted-data, wherein a database object can be a table, a partition, a row, or a column in a row. Furthermore, a database object can have an expiration time, and it can be stored in an archive, which is typically used to store large amounts of data for long periods using a slower, but cheaper storage medium than the storage medium used by the database. The system then identifies a set of keys for the encrypted-data using the object-identifying information. Next, the system deletes the set of keys, thereby expiring the encrypted-data. Note that, deleting the set of keys ensures that the secure key repository does not contain any stale keys associated with expired encrypted-data.
摘要翻译：本发明的一个实施例提供一种能够使加密数据过期的系统。在操作期间，系统接收包含对象标识信息的到期请求，该信息可用于标识包含加密数据的一组数据库对象，其中数据库对象可以是表，分区，行，或一列。此外，数据库对象可以具有到期时间，并且可以将其存储在通常用于使用比数据库使用的存储介质更慢但更便宜的存储介质来长时间存储大量数据的存档。然后，系统使用对象识别信息来标识用于加密数据的一组密钥。接下来，系统删除一组密钥，从而使加密数据过期。请注意，删除密钥集可确保安全密钥存储库不包含与过期的加密数据相关联的任何过时的密钥。

摘要： A method and apparatus are described for sharing a session to access a database. A database server receives, in a session, a session context identifier and a command. The session context identifier identifies a session context to use for the session. The session context is a set of information or commands that plug into a session state and specify how commands in the session are to be performed for a particular user or privilege level. In response to receiving the identifier, the database server associates the session context with the database session for the connection. The database server uses the session context to process the command. The session context may then be detached from the session, allowing another user to attach to the session via another session context.
摘要翻译：描述了一种用于共享会话以访问数据库的方法和装置。数据库服务器在会话中接收会话上下文标识符和命令。会话上下文标识符标识用于会话的会话上下文。会话上下文是一组插入会话状态的信息或命令，并指定如何为特定用户或特权级别执行会话中的命令。响应于接收到标识符，数据库服务器将会话上下文与连接的数据库会话相关联。数据库服务器使用会话上下文来处理命令。然后会话上下文可以从会话分离，允许另一用户经由另一会话上下文附加到会话。

摘要： An application platform examines, at runtime, various specified aspects of an application environment in which an application interacts with a user. Such examinations are made to determine a state for each of the various specified aspects. Further, the platform automatically activates particular application environment roles for the user depending on the result of the examinations. For example, an application environment role may be activated representing a particular detected mode of communication (e.g., encrypted network communications) or a particular detected manner of authentication (e.g., password authentication). Such activations are based on the detected states and specified states for the various specified aspects of the application environment. Such activations may occur in the context of an application attempting to perform an operation on an access controlled object on behalf of a user. Further, such activations may occur in the context of establishing or maintaining a user session for a user of an application.

摘要： One embodiment of the present invention provides a system for managing keys. During operation, the system authenticates a client at a key manager. Next, the system receives a token from the client at the key manager, wherein the token is associated with a customer key, and includes a token authenticator. This token authenticator comprises one-half of an authenticator pair which is used to determine if the client is the owner of the customer key. Next, the system decrypts the token using a master key. The system then verifies a client authenticator, which comprises the other half of the authenticator pair which is used to determine if the client is the owner of the customer key. If the client is the owner of the customer key, the system sends the customer key to the client, which enables the client to encrypt/decrypt data. Finally, the client deletes the customer key.

摘要： One embodiment of the present invention provides a system that facilitates configuring a database. During operation, the system requests database configuration information from a directory server that stores configuration information for a plurality of database instances. In response to this request, the system receives the database configuration information, and configures the database in accordance with the database configuration information received from the directory server. This enables the database server to be configured without requiring manual configuration operations by a database administrator.

摘要： One embodiment of the present invention provides a system that facilitates using an external security device to secure data in a database without having to modify database applications. The system operates by receiving a request at the database to perform an encryption/decryption operation, wherein the encryption/decryption operation is performed with the assistance of the external security module in a manner that is transparent to database applications. In response to the request, the system passes a wrapped (encrypted) column key (a key used to encrypt data within the database) to an external security module, wherein the wrapped column key is a column key encrypted with a master key that exists only within the external security module. The system then unwraps (decrypts) the wrapped column key in the external security module to retrieve the column key. Next, the system returns the column key to the database. The system then performs an encryption/decryption operation on data in the database using the column key. Finally, the system erases the column key from memory in the database.
