SAFE APPLICATION DISTRIBUTION AND EXECUTION IN A WIRELESS ENVIRONMENT

摘要

The present invention provides safe and secure application distribution and execution by providing systems and methods that test an application to ensur e that it satisfies predetermined criteria associated with the environment in which it will execute. Furthermore, by using rules and permission lists, application removal, and a modification detection technique, such as digital signatures, the present invention provides mechanisms to safely distribute a nd execute tested, or untested, applications by determining whether the application has been modified, determining if it has permission to execute i n a given wireless device environment, and removing the application.
