System and method for authenticating components in wireless home entertainment system
First Claim
Patent Images
1. A home entertainment system, comprising:
- at least one wireless system server having at least one communication system;
at least one wireless component having at least one communication system configured for communicating with the communication system of the server;
a remote control device configured for communicating with the server and the component and generating a wireless signal, the wireless signal being used to generate an authentication signal, the authentication signal being used for authentication between the component and server;
wherein the server sends a signal representing the wireless signal to the component, the component also receiving the wireless signal from the remote control device, the component comparing the wireless signal to the signal from the server representing the wireless signal and if a match is found, determining that authentication exists between the server and component and otherwise not determining that authentication exists between the server and component; and
wherein the server includes at least one button and the authentication signal is generated from the wireless signal only if the button is pressed within a predetermined time of receiving the wireless signal from the remote control device.

8. A method for authenticating a component in a home network with a server in the network, comprising:
-
pointing a remote control device at the server; pressing a button indicating that authentication is impending, the button being on at least one of the server or the remote control device; randomly selecting a button on the remote control device; pressing the randomly selected button to generate a wireless signal; pointing the remote control device at the component; pressing the randomly selected button to generate the wireless signal; from at least one of;
the server, or the component, sending a signal representing the wireless signal to the other of;
the server, or the component, which compares the wireless signal it received from the remote control device with a signal assumed to represent the wireless signal and if a match is found, determines that authentication exists between the server and component and otherwise does not determine that authentication exists between the server and component. - View Dependent Claims (9, 10, 11, 12)

13. A method for authenticating a component in a home network with a server in the network, comprising:
-
pointing a remote control device at the server; pressing a button indicating that authentication is impending, the button being on at least one of the server or the remote control device; randomly selecting a button on the remote control device; pressing the randomly selected button to generate a wireless signal; at the server, deriving an encryption key from the wireless signal; pointing the remote control device at the component; pressing the randomly selected button to generate the wireless signal;
at the component, deriving the encryption key from the wireless signal; andexchanging authentication information between the server and component, the authentication information being encrypted by the key. - View Dependent Claims (14, 15, 16)
