A signed application descriptor file ( ) is used instead of X.509 certificates to authenticate a portable application code, such as a JAVA archive (JAR) file. The signed ADF includes an application descriptor file ( ), file hash ( ) of the JAR file ( ), a developer descriptor file ( ), signed time stamp ( ), and a developer's certificate ( ). A network client device ( ) includes limited computing resources ( ) and a virtual machine environment for executing the portable code ( ). Furthermore the client device contains a set of cryptographic, digital keys for authenticating parts of the signed ADF, which are further used to authenticate the JAR file.

Method for authenticating a JAVA archive (JAR) for portable devices

A controller in a communication device receives a request, from a process operating in the communication device, to subscribe to a data routing service that is managed by the controller. In response to the request, the controller assigns a destination identifier to the process and adds the process and the assigned destination identifier to a routing table that is stored in a memory associated with the controller. Data subsequently received from a data source is routed to the process or to one of multiple communication ports by the controller by reference to the destination identifier, or the absence of a destination identifier, stored in the routing table.
