    • 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。

    • A system and method for using a client-side hypervisor in conjunction with a secure network-side monitoring mechanism to detect removable media insertions since a client's last network session with the secure network is presented. The hypervisor uses a “client-side insertion value” to track the number of times that a user inserts removable media into a socket located on the client. When the client is connected to the secure network, the client's hypervisor notifies the secure network of each insertion and the secure network increments a “secure network-side tracker value.” For each login request, the client includes the client-side insertion value, which the secure network compares against its secure network-side tracker value. When the two values are different, the secure network sends an action request to the client, such as a request to perform a full system scan. Once the client performs the action, the client's hypervisor resets its client-side insertion value and attempts to logon to the secure network again.
    • 提出了客户端管理程序与安全网络侧监视机制结合使用以检测可移动介质插入的系统和方法,因为客户端与安全网络的最后一次网络会话。 管理程序使用“客户端插入值”来跟踪用户将可移动媒体插入位于客户端上的套接字的次数。 当客户端连接到安全网络时,客户端的管理程序会将安全网络通知每个插入,并且安全网络会增加“安全网络侧跟踪器值”。 对于每个登录请求,客户端包括客户端插入值,安全网络与安全网络侧跟踪器值进行比较。 当两个值不同时,安全网络向客户端发送动作请求,例如执行完整系统扫描的请求。 一旦客户端执行操作,客户端的管理程序将重置其客户端插入值,并尝试再次登录到安全网络。
