Definitions
- the present invention relates generally to in-home wireless entertainment systems.
- In-home wireless entertainment systems can include a central server and various components that are in wireless communication with the server and that are dispersed throughout the house.
- TVs, digital video disk (DND) recorders, NCRs, telephones, personal digital assistants (PDAs), appliances, and so on may all be linked in a wireless entertainment system.
- DND digital video disk
- NCRs digital video disk
- PDAs personal digital assistants
- the problem to which the present invention is directed is authenticating wireless components to access the system.
- a wired system authentication is not generally a problem, since a component must be physically present in the home to communicate with the system.
- a wireless system it is possible for an eavesdropper or otherwise unauthorized person outside the home to access the system using the wireless network, which typically extends beyond the walls of the house.
- a wireless home entertainment system includes a server that has a manipulable authentication element and one or more components in wireless communication with the server. Each component has manipulable authentication element. A person can cause the server to regard the component as being authenticated by manipulating the authentication elements.
- the server includes logic for authenticating the component when the elements are manipulated simultaneously with each other. In an alternate embodiment, the server includes logic for authenticating the component when the elements are manipulated within a predetermined time threshold of each other. If desired, the server may include two authentication elements establishing respective
- the preferred component includes logic for transmitting a component identification in response to manipulating the authentication element on the component.
- the component can include logic for transmitting an encryption result generated at least in part using a component identification.
- the server may include means for indicating that the component is authenticated, such as by generating an audible or visual signal.
- a method for authenticating, to a server, a component in wireless communication with the server includes depressing an authentication button on the server, and depressing an authentication button on the component to cause the component to transmit a message.
- the message also includes returning "authenticated” at the server in response to receiving the message only if the buttons are depressed simultaneously with each other or within a predetermined time period of each other.
- a logic component includes means, invokable by manipulating a first authentication element, for receiving an identification message transmitted in response to manipulation of a second authentication element.
- the logic component includes means for reftirning "authentication” only if the elements have been manipulated together or within a predetermined period of each other.
- Figure 1 is a block diagram of the system architecture of the present invention
- Figure 2 is a flow chart showing the authentication logic
- Figure 3 is a flow chart showing alternate authentication logic.
- a wireless home entertainment system is shown, generally designated 10, which includes a server 12 that can be implemented by any appropriate processor 13 and one or more components 14 that are in wireless communication with the server 12.
- a server 12 that can be implemented by any appropriate processor 13 and one or more components 14 that are in wireless communication with the server 12.
- Figure 1 shows two components 14, although more components 14 can be used.
- Non-limiting examples of embodiments of the components 14 are televisions, including portable flat-panel TVs, digital video disk (DND) players, VCRs, telephones, personal digital assistants (PDAs), and household appliances.
- DND digital video disk
- PDAs personal digital assistants
- the server 12 can access a database 16 of, e.g., audio-video content.
- the server 12 can also include a wireless transceiver 18, e.g., a code division multiple access (CDMA) transceiver.
- CDMA code division multiple access
- Other wireless communication principles can be used, including other radiofrequency, infrared, and acoustic transmission principles.
- the server 12 includes at least one and more preferably two human-manipulable authentication elements 20, 22.
- the elements 20, 22 may be implemented as buttons or toggles or switches or their functional equivalents.
- authentication element is meant a manipulative device such as a button that does not function as a data entry device such as a keypad or keyboard, but instead is a single-purpose element that cannot be used for general data entry but that simply activates the server to function in accordance with the logic below.
- a first authentication element 20, when manipulated indicates that the component 14 sought to be registered for authentication is to have unlimited system access.
- a second authentication element 22, when manipulated indicates that the component 14 sought to be registered for authentication is to have limited system access, e.g., access to only predetermined content or channels.
- the server 12 may include an indication 24 that can be implemented by a light emitting diode (LED), a front panel display message, a message on a display screen associated with the server 12, etc.
- the indication 24 is used to indicate successful registration for authentication of
- each component 14 may include a processor 26 and a wireless transceiver 28 for communicating with the server 12 and/or other components 14.
- the component processor 26 and server processor 13 may act alone or in concert with each other to execute the logic herein.
- each component 14 includes at least one human- manipulable authentication element 30.
- Figure 2 shows the authentication logic of the present invention, as can be embodied in software or hardware.
- Figure 2 is in logic flow format for convenience of disclosure, but part or all of the logic can be implemented by state machines or other logic devices.
- a user wishing to register a component 14 for authentication (also generally referred to herein as "authenticating” the component) simultaneously manipulates the component authentication element 30 and one of the server authentication elements 20, 22 (depending on the level of system access to be granted the component 14).
- Manipulation of the server authentication element 20 causes the server to be configured to receive a message from the component 14. This message is transmitted at block 34 by the component 14 in response to manipulation of the component authentication element 30.
- manipulation at block 32 can include depressing and holding down the buttons until the indication 30 is activated as described below.
- the message from the component 14 includes a unique identification associated with the component 14.
- This ID can be programmed into the component 14 at time of manufacture of either the processor 26 chip or component 14 manufacture or assembly, and can be input to a write-once read many type of device, such as a fusible link ROM.
- the message transmitted by the component 14 can be an encryption result of the ID.
- the ID can be used as a seed for a key generation algorithm.
- the key which may not be readable from any outside component, might not be transmitted, but rather only the results of an encryption algorithm that uses the key. This can be part of an overall authentication key exchange that might be implemented in accordance with public key/private key principles known in the art.
- the indication 24 can be activated to so inform the user.
- the component 14 has been authenticated to the server 12 to afford the component 14 the level of system 10 access indicated by the server authentication element 20, 22 that was manipulated. Subsequently, the component 14 can automatically communicate with the server 12 in accordance with session wireless authentication procedures known in the art.
- FIG. 3 shows that in an alternate embodiment, the server authentication element and component authentication element need not be manipulated simultaneously with each other, but rather can be manipulated within a predetermined time period of each other, e.g., a second or two. Accordingly, at block 38 the server authentication element 20, 22 is manipulated and released. Then, at block 40 the component authentication element 30 is manipulated and released. At decision diamond 42 it is determined whether the manipulations occurred within the predetermined period and if not, "fail" is returned at state 44. Otherwise, "authenticate” is indicated at block 46. In this embodiment, clocks in the component 14/server 12 can be synchronized.
