Electronic Game Using Cryptography Patents (Class 380/251)
  • Patent number: 7409061
    Abstract: Methods and Systems for securely distributing software in a subscription-based environment are provided. In an example embodiment, a Game Security Facility (“GSF”) associated with a game server is used to manage secure communications with game clients. The GSF typically manages secure communication of the accounting and billing information and secure communication of game session data. In typical operation, the game client generates a pass-phrase that transparently includes a unique identifier of the machine upon which the subscription software will reside. RSA-type key pairs that are then generated using this pass-phrase will be associated uniquely with both the game player and with the machine upon which the software resides, thus preventing unauthorized copying to another machine or unauthorized use by a third party.

  • Patent number: 7362862
    Abstract: The present invention provides authentication of computer generated game or test results (“outcomes”), and a system by which persons who play games or take tests on a game or testing computer, respectively, may submit the outcomes of the games or tests to a central authority having at least one central computer, and have the central computer “certify” those outcomes as being accurately reported and fairly achieved. This certification of the computer generated result constitutes a “remote-auditing” of the activity taking place on the game computer. In one application, the system enables computer generated game tournaments in which players play the games on game computers and compete against each other by submitting the outcomes for those tournament games to the central computer, which certifies the outcomes and rates and ranks the players. In another application, the system provides for players of computer games to obtain a certified ranking and rating without participation in a tournament.

  • Patent number: 7031473
    Abstract: 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.

  • Publication number: 20020034299
    Abstract: A secure cashless gaming system comprises a plurality of gaming devices which may or may not be connected to a central host network. Each gaming device includes an intelligent data device reader which is uniquely associated with a security module interposed between the intelligent data device reader and the gaming device processor. A portable data device bearing credits is used to allow players to play the various gaming devices. When a portable data device is presented to the gaming device, it is authenticated before a gaming session is allowed to begin. The intelligent data device reader in each gaming device monitors gaming transactions and stores the results for later readout in a secure format by a portable data extraction unit, or else for transfer to a central host network.

  • Publication number: 20020032868
    Abstract: In order to protect against unauthorized duplication of a library file, or the like, according to the present invention, an executable module is generated. The executable module is generated by generating, with decryption of an encrypted protective object, a protective object containing a procedure for terminating a process operation due to invalid relationship between a first protect code and a second protect code contained in the executable module, linking the resultant decrypted protective object with other object, and writing a protect code. Then, the decrypted protective object is deleted after linking with the other object.

  • Patent number: 6292569
    Abstract: Secure computation environments are protected from bogus or rogue load modules, executables and other data elements through use of digital signatures, seals and certificates issued by a verifying authority. A verifying authority—which may be a trusted independent third party—tests the load modules or other executables to verify that their corresponding specifications are accurate and complete, and then digitally signs the load module or other executable based on tamper resistance work factor classification. Secure computation environments with different tamper resistance work factors use different verification digital signature authentication techniques (e.g., different signature algorithms and/or signature verification keys)—allowing one tamper resistance work factor environment to protect itself against load modules from another, different tamper resistance work factor environment. Several dissimilar digital signature algorithms may be used to reduce vulnerability from algorithm.

  • Patent number: 6272223
    Abstract: An apparatus for implementing a game having a deterministic component and a non-deterministic component wherein a player uses the game through at least one player interface unit. Each player interface unit generates a player record indicating player-initiated events. A random number generator provides a series of pseudo-random numbers and a rules library stores indexed rules for one or more games. An interface registry stores mapping records where the mapping records are used to associate the player-initiated events to pre-selected rules in the rules library. A control means is coupled to the player interface to receive the output of the player interface unit, coupled to the interface registry, the rules library, and the random number generator.
