A network architecture for console-based gaming systems enables secure communication among multiple game consoles over a local area network. The system architecture supports a three-phase secure communication protocol. The first phase involves generating shared keys that are unique to an authentic game console running an authentic game title. In the second phase, a "client" console attempts to discover existing game sessions being hosted by a "host" game console by broadcasting a request over the local area network. The broadcast request is protected using the shared keys. If the host console agrees to let the client console play, the host console generates session keys that are returned to the client console. The third phase involves a key exchange in which the client and host consoles exchange data used to derive one or more secrets for securing future communications. The key exchange is protected using the session keys. |

DETAILED DESCRIPTION The following discussion is directed to console-based gaming systems and techniques for establishing secure communications between multiple gaming systems connected via a local area network (LAN).
The discussion assumes that the reader is familiar with basic cryptography principles, such as encryption, decryption, authentication, hashing, and digital signatures.
For a basic introduction to cryptography, the reader is directed to a text written by Bruce Schneier and entitled, "Applied Cryptography: Protocols, Algorithms, and Source Code in C," published by John Wiley & Sons, copyright 1994 (second edition 1996), which is hereby incorporated by reference.
Gaming System FIG.
1 shows an exemplary gaming system 100.
It includes a game console 102 and up to four controllers, as represented by controllers 104(1) and 104(2).
The game console 102 is equipped with an internal hard disk drive and a portable media drive 106.
The portable media drive 106 supports various forms of portable storage media as represented by optical storage disc 108.
Examples of suitable portable storage media include DVD, CD-ROM, game discs, game cartridges, and so forth.
The game console 102 has four slots 110 on its front face to support up to four controllers, although the number and arrangement of slots may be modified.
A power button 112 and an eject button 114 are also positioned on the front face of the game console 102.
The power button 112 switches power to the game console and the eject button 114 alternately opens and closes a tray of the portable media drive 106 to allow insertion and extraction of the storage disc 108.
The game console 102 connects to a television or other display (not shown) via A/V interfacing cables 120.
A power cable 122 provides power to the game console.
The game console 102 may further be equipped with internal or externally added network capabilities, as represented by the cable or modem connector 124 to facilitate access to a network, such as a local area network (LAN) or the Internet
