Abstract
A system for securely communicating callback signals to a head end includes a callback server and a user device communicating a request to open a callback session to the callback server. The callback server opens a first session between the callback server and a user device. The user device communicates an encrypted callback data signal to the callback server through the first session. The callback server opens a second session between the callback sever and a conditional access system associated with a head end, verifies the callback data signal at callback server, and communicates the encrypted callback data signal to the conditional access system through the second session. The conditional access system decrypts the encrypted callback data signal to form decrypted callback data.
