    • A wireless network client is described which obtains access to the resources of a backbone network provided by a wireless access point. The client is adapted to receive a reassociation request from an access point which is able to detect a degraded condition on the backbone network and inform clients of the degraded condition. Upon detecting the degraded condition, the access point transmits or broadcasts a reassociation request to one or more clients associated with the access point. Information can also be sent identifying the degraded performance of the backbone network and can include other information useful to clients. Once a client has received the reassociation request and/or the informed identifying the degraded performance, the clients seek access to the backbone network through other access points which are not experiencing degraded performance. The seek preferably omits the access point identified as experiencing degraded backbone performance.
    • 描述了获得对由无线接入点提供的骨干网的资源的访问的无线网络客户端。 客户机适于从接入点接收到重新关联请求,该接入点能够检测骨干网上的恶化状况并通知客户端处于恶化状态。 在检测到恶化条件时,接入点向与接入点相关联的一个或多个客户端发送或广播重新关联请求。 还可以发送信息来识别骨干网络的性能下降,并且可以包括对客户端有用的其他信息。 一旦客户端已经接收到重新关联请求和/或被通知识别降级的性能,则客户端通过未经历性能下降的其他接入点寻求对骨干网的接入。 寻找优选地省略被识别为经历降级的骨干性能的接入点。

    • A method for providing centralized user authorization to allow secure sign-on to a computer system is disclosed. In response to a user attempting to boot up a computer system, a message is sent to a trusted server by a hypervisor within the computer to request a new hard drive password for the computer system. If the user is not authorized to access the computer system, a packet is sent by the trusted server to instruct the hypervisor to stop any boot process on the computer system. If the user is authorized to access the computer system, a packet containing a partial hard drive password is sent by the trusted server to the computer system. The packet is then encrypted with a system public key by the computer system to yield the partial hard drive password. The computer system subsequently combines the partial hard drive password with a user password to generate a new complete hard drive password to continue with the boot process.
    • 公开了一种用于提供集中式用户授权以允许对计算机系统进行安全登录的方法。 响应于尝试启动计算机系统的用户,由计算机内的虚拟机管理程序向可信服务器发送消息,以请求计算机系统的新的硬盘驱动器密码。 如果用户没有权限访问计算机系统,则可信服务器发送一个数据包,以指示管理程序停止计算机系统上的任何引导过程。 如果用户被授权访问计算机系统,则包含部分硬盘驱动器密码的分组由可信服务器发送到计算机系统。 然后,计算机系统使用系统公钥对数据包进行加密,以产生部分硬盘驱动器密码。 计算机系统随后将部分硬盘驱动器密码与用户密码相结合,以生成新的完整硬盘驱动器密码,以继续引导过程。
