Methods and systems for re-securing a compromised channel in a satellite signal distribution environment

A non-transitory computer-readable storage medium storing instructions for execution by a computing entity of a set top box (STB) capable of encrypting communications for a channel stacking switch using a public key of the channel stacking switch, wherein execution of the instructions by the computing entity causes the STB to:

• obtain a message from a head end;
• extract electronic counter measure (ECM) data from the message;
• send the ECM data to the channel stacking switch, the channel stacking switch distributing satellite signals to a plurality of receivers;
• receive, in response to sending the ECM data to the channel stacking switch, a new public key of the channel stacking switch;
• and
• encrypt communications destined for the channel stacking switch using the new public key of the channel stacking switch.

A non-transitory computer-readable storage medium storing instructions for execution by a computing entity of a channel stacking switch (CSS) distributing satellite signals to a plurality of receivers, wherein execution of the instructions by the computing entity causes the CSS to:

• maintain a private key and a public key;
• obtain electronic counter measure (ECM) data sent by a set top box in communication with the channel stacking switch;
• obtain an identifier of the channel stacking switch;
• formulate a new public key based on the private key, the identifier and the ECM;
• and
• render the new public key available to the set top box.
