Abstract

According to the invention, a method for securing a plaintext object within a content receiver is disclosed. In one step, a secure portion of a secure object and a plaintext remainder of the secure object are received. Which portion of the secure object is the secure portion is determined. The secure portion is decrypted to provide a plaintext portion. The plaintext object that comprises the plaintext portion and the plaintext remainder is formed. The plaintext object is stored including authentication and authorization.

15. A method for authenticating and authorizing a specific portion of broadcast content within a conditional access broadcast network, the method comprising steps of:

receiving the specific portion of broadcast content with a receiver that is one of a plurality of receivers adapted to receive content via the conditional access broadcast network, wherein the specific portion of broadcast content is broadcast to and received by each receiver within the plurality of receivers;

authenticating the specific portion of broadcast content wherein the authenticating step comprises steps of;

calculating a code from the specific portion of broadcast content;

comparing the code to a predetermined code;

authorizing the specific portion of broadcast content for use by the receiver; and

running a process that checks authorization for the receiver to use the received specific portion of broadcast content.

16. The method for authenticating and authorizing a specific portion of broadcast content of claim 15, the method further comprising a step of detecting an event that triggers at least one of authorization of the receiver to use the received specific portion of broadcast content.

17. The method for authenticating and authorizing a specific portion of broadcast content of claim 16, wherein the event is at least one of:

an unpredictable period;

or a predetermined period measured relative to the loading the received specific portion of broadcast content.

18. The method for authenticating and authorizing a specific portion of broadcast content of claim 15, wherein the step of authenticating the specific portion of broadcast content includes decryption of at least a segment of the specific portion of broadcast content.

19. The method for authenticating and authorizing a specific portion of broadcast content of claim 15, wherein the specific portion of broadcast content includes at least one of software, drivers, firmware, video, audio, and data.

20. The method for authenticating and authorizing a specific portion of broadcast content of claim 15, further comprising steps of:

receiving first authorization information; and

receiving second authorization information that replaces the first authorization information so as to extend authorization rights.
