    • A local game-area network includes a plurality of gaming devices and local game-area servers. Each local game-area server is associated with a corresponding gaming device. Each local game-area server in the local game-area network is operatively associated with every other local game-area server in the local game-area network. Additionally, one of the local game-area servers is a host local game-area server while the remaining gaming devices and associated local game-area servers are clients. Furthermore, the host status of the host local game-area server moves dynamically to an available local game-area server in the local game-area network in response to the host local game-area server becoming non-operational.
    • 本地游戏区域网络包括多个游戏设备和本地游戏区服务器。 每个本地游戏区域服务器与相应的游戏设备相关联。 本地游戏区域网络中的每个本地游戏区域服务器与本地游戏区域网络中的每个其他本地游戏区域服务器可操作地相关联。 此外,其中一个本地游戏区域服务器是主机本地游戏区服务器,而剩余的游戏设备和相关联的本地游戏区域服务器是客户端。 此外,主机本地游戏区域服务器的主机状态响应于主机本地游戏区域服务器变得不可操作地动态地移动到本地游戏区域网络中的可用本地游戏区域服务器。

    • Disclosed is a system and method that uses digital signature technology to authenticate the contents of one or more manifests located on a storage device. Each manifest contains a list of file records, where each record contains the name of a file stored on the storage device, and a signature value derived from the contents of the file. At boot time, the gaming machine first authenticates the contents of the manifest and then authenticates the contents of the files using the signature value stored in the manifest. Files are verified using the signature, as they are needed, during the boot up of the operating system and throughout normal operation. This method reduces the boot time of the gaming machine and eliminates the need to check digital signatures for each individual file or over the entire contents of a non-secure media. Similarly, a method of adding authentication ability to legacy software components without necessarily altering the legacy software components is disclosed. Introduction of a stronger authentication algorithm, or when a private key has been compromised would normally require the software component to be re-built to support the new algorithm or private/public key pair; however, a method is disclosed where algorithms and key pairs may be changed and applied to legacy software without having to re-built, re-test, re-sign, or re-submit the component to regulatory agencies for approval. Also disclosed is a system and method of establishing a trusted environment containing a gaming operating system and associated authentication module, file system drivers, and/or network drivers that may be used to in the process of authenticating contents of one or more manifests located on a storage device.
    • 公开了一种使用数字签名技术认证位于存储设备上的一个或多个清单的内容的系统和方法。 每个清单包含文件记录的列表,其中每个记录包含存储在存储设备上的文件的名称,以及从该文件的内容导出的签名值。 在启动时,游戏机首先对清单的内容进行身份验证,然后使用存储在清单中的签名值来验证文件的内容。 在操作系统的启动过程中以及整个正常操作过程中,都需要使用签名来验证文件。 该方法减少了游戏机的启动时间,并且消除了检查每个单独文件的数字签名或非安全媒体的整个内容的需要。 类似地,公开了一种向传统软件组件添加认证能力而不必改变传统软件组件的方法。 引入更强大的认证算法,或者当私钥被破坏时,通常需要重新构建软件组件以支持新算法或专用/公开密钥对; 然而,公开了一种方法,其中可以将算法和密钥对改变并应用于遗留软件,而不必重新构建,重新测试,重新签名或将组件重新提交给管理机构以供批准。 还公开了一种建立包含游戏操作系统和相关联的认证模块,文件系统驱动程序和/或网络驱动程序的可信环境的系统和方法,所述认证模块,文件系统驱动程序和/或网络驱动程序可用于在认证位于 储存设备。

    • The invention comprises methods and apparatus for modifying or converting a gaming machine to permit fully cash-less or optional cash-less transactions in a manner which avoids changing the existing firmware or software of the gaming machine. In an optional cash-less arrangement, a player selects the form by which funds are added or paid to the machine and/or paid out by machine. The cash-less forms of payment may comprise the acceptance and/or payment of funds or value electronically to a system account, coded card or ticket, smart card, magnetic card and other non-cash elements. In one or more embodiments, the invention consists of hardware and/or software for intercepting and/or emulating any or all combinations of the electronic signals associated with the coin acceptor, cash out button, hopper, serial communication interface(s) and bill acceptor(s) associated with a gaming machine to create optional currency transfers. These currency transfers comprise the dispensing or adding of coins, tokens, bills, or any physical item of value and/or any method of transferring funds electronically.
    • 本发明包括用于修改或转换游戏机以允许以避免改变游戏机的现有固件或软件的方式的完全无现金或可选的无现金交易的方法和装置。 在可选的无现金安排中,玩家选择将资金添加或支付给机器和/或由机器支付的形式。 无现金形式的支付可以包括以电子方式接收和/或支付系统帐户,编码卡或票证,智能卡,磁卡和其他非现金元件。 在一个或多个实施例中,本发明由硬件和/或软件组成,用于拦截和/或模拟与硬币接收器,现金出口按钮,料斗,串行通信接口和票据接收器相关联的电子信号的任何或所有组合 (s)与游戏机相关联以创建可选的货币转移。 这些货币转移包括以电子方式分配或添加硬币,令牌,票据或任何物理价值物品和/或任何转移资金的方法。
