Abstract
A method for managing access to a scrambled event, selected from an electronic program guide, of a service provider (including broadcast television networks, cable television networks, digital satellite systems, and internet service providers). Access to the event is only achieved if the descrambling key is obtained from a digitally signed message associated with the event in the electronic program guide. Authentication of the electronic program guide provider involves decrypting the digital signature using a public key of the guide provider.
