A set top box or similar device incorporating key management and certification support functions for establishing and maintaining compliance and flexibility with respect to applicable certification procedures and security measures when integrating untrusted components with an underlying secure operating system environment of the device. In various embodiments, the device incorporates untrusted software framework, such as an Android framework supported by a secure Linux operating system environment. The key management and certification support system operates to select hardware and software components of the device for use in establishing media pathways conforming to a desired level of security, and may be further operable to restrict access to a pathway in response to detection of an attempt to exploit the media pathway in an unauthorized manner. In one embodiment, a service operator or content provider may provide requisite certification or security requirements, or otherwise assist in selection of pathway components. |
