A system for security and authorization processing in digital terminals. The processing load of a security processor ( ) at the terminal ( ) is reduced by configuring a multiple applications manager (MAM) ( ) to determine if frequently-transmitted application data should be downloaded. The security processor is used by the MAM to build a local virtual application table ( ) that indicates which applications are authorized for downloading. The security processor configures the terminal with an authorization state so that it knows which applications it is authorized to download, i.e., the applications ( ) whose required authorization state correlate with the terminal's configured authorization state. The security processor is accessed when the terminals authorization state changes, or when a required authorization state of an application changes. These events are typically relatively infrequent.
