  • Methods and systems for re-securing a compromised channel in a satellite signal distribution environment
    Patent number: 10321201
    Abstract: A method implemented by a set top box that encrypts communications for a channel stacking switch (CS) using a public key of the CSS, the method comprising: obtaining a message from a head end; extracting electronic counter measure (ECM) data from the message; sending the ECM data to the CSS; receiving, in response to the sending, a new public key of the CSS; encrypting communications for the CSS using the new public key of the CSS. Also, a method for implementation by a CSS, comprising: maintaining a private key and a public key; obtaining ECM data sent by a set top box in communication with the CSS; obtaining an identifier of the CSS; formulating a new public key based on the private key, the identifier and the ECM; rendering the new public key available to the set top box.
    Type: Grant
