Abstract

Official abstract text for this publication.

A set top box or like device utilizing trusted applications in conjunction with an untrusted software framework. In one implementation, trusted or certified applications are received from a service provider for execution by a software framework of the device. Certification of a trusted application may entail, for example, verifying that the application is executable by the device in a manner consist with the industry standard certification process. The software framework may comprise, for example, an Android framework supported by an underlying. Linux operating system environment and isolated in a Linux resource container. A secure access client/server interface may also be provided to support interactions between the software framework and trusted portions of the device. In further embodiments, both trusted applications and a set top box application utilized by the device to perform traditional set top box operations are implemented in at least one version of an Android or like framework.
