Method and device for securing content delivery over a communication network via content keys
First Claim
1. A device, located at a remote site in communication with a network having at least one server, comprising:
- a processor in communication with a memory, said processor operable to execute code for;
receiving a first information item comprising an access code and a content key scrambled using a key known by said remote site;
descrambling said first information item using a corresponding decrypting key; and
receiving a second information item scrambled using said content key after said server hosting the second information item verifies said access code.

Abstract
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).

16. A method for transferring secure content over a network comprising the steps of:
-
receiving a request for content at a first server over a first network from a file requesting device, said request including an encryption key known to a designated remote site;
generating a first information containing a content access credential and a content key at said server; and
transferring said first information item to said designated remote site having a file receiving device, wherein said content access credential and said content key are scrambled using said encryption key. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
