ABSTRACT:
Methods and apparatus provide for: requiring that a content provider seeking to have its content executed by a processing system enter into an accord with a processing system provider; receiving a second key and a digital signature from the content provider to the processing system provider, the second key being operable to decrypt the content when it has been encrypted with a first key, and the digital signature indicating that the accord has been reached; receiving the encrypted content from the content provider in a memory of the processing system; and preventing use of one or more processing resources of the processing system that are otherwise operable to facilitate the execution of the content unless the digital signature is received from the processing system provider.
