Abstract: Discovery and distribution of game session security information includes receiving a request to generate a new game session from a computing device and maintaining a record of a game session identifier for the new game session and a game session key for the new game session, and making the new game session available for other computing devices to join. A request for information describing one or more of a plurality of game sessions may also be received and responded to with the information describing the one or more game sessions as well as a session key that can be used to communicate with at least one of the one or more other computing devices that are part of the game session.
