    • An apparatus, system, and process are disclosed for dynamically determining a best network service for an electronic computing device. A network query module queries two or more active networks to determine the network characteristics, such as bandwidth, security level, and cost, of each network. A service level module determines a service level associated with each active network. The service level is determined based on an algorithm using the network characteristics of each network. A best network module determines the best network from the active networks based on the service levels of each network, and a network connection module dynamically connects the electronic computing device to the best network. The network selection apparatus may also maintain and use a profile module to store default, user-defined, application, and network profiles. A dynamic switching module may dynamically switch between active networks as the service levels of individual networks are re-evaluated and the network characteristics of each network change.
    • 公开了用于动态地确定电子计算设备的最佳网络服务的装置,系统和过程。 网络查询模块查询两个或多个活动网络,以确定每个网络的网络特性,如带宽,安全级别和成本。 服务级别模块确定与每个活动网络相关联的服务级别。 基于使用每个网络的网络特性的算法确定服务水平。 最佳网络模块根据每个网络的服务级别确定来自活动网络的最佳网络,网络连接模块将电子计算设备动态连接到最佳网络。 网络选择装置还可以维护和使用简档模块来存储默认的,用户定义的,应用和网络简档。 动态切换模块可以在重新评估各个网络的服务级别并且每个网络的网络特性发生变化时,在活动网络之间动态切换。

    • 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。
