摘要:
A method for descrambling secure content received over a network is disclosed. The method is operable at a receiving device (150) located at a remote site in communication with a network (140) for receiving a first information item scrambled using an encrypting key (Pu) known by the remote site, descrambling the first information item using a corresponding decrypting key, wherein the information item includes an access code (CAC) and a content key (Kc), receiving a second information item, scrambled using the content key after a server, (120) hosting the second information verifies the access code (CAC) and descrambling the second information item using the content key (Kc).
