Abstract:

A transactional sealed storage system enables data to be accessed according to transactional properties and also enables access to the data to be restricted to secured applications. The transactional properties according to which the data may be accessed may include, for example, at least some levels of atomicity, consistency, isolation, and durability. The access to the data may be restricted by, for example, employing a double layer security policy that involves encrypting the data and also authenticating any application that requests access to the encrypted data.
