Abstract

The invention discloses a credible virtual machine platform, which comprises a hard disk (11), a USB Key (10) and a nonprivileged virtual machine (6), and also comprises credible hardware (1), a security enhancement virtual machine monitor (2), a management virtual machine (3), a communication virtual machine (4) and a driving virtual machine (5). The security enhancement virtual machine monitor (2) is bidirectionally connected with the credible hardware (1) and the management virtual machine (3) respectively; the management virtual machine (3), the driving virtual machine (5) and the communication virtual machine (4) are privileged virtual machines; the management virtual machine (3) creates, manages, destroys and transfers other virtual machines; the driving virtual machine (5) provides driving needed by the operation of the virtual machine and management of a virtual credible password module; and the communication virtual machine (4) takes charge of communication between inner virtual machines and a virtual machine platform. The credible virtual machine platform has the advantages of effectively guaranteeing the safety and credibility of an operating environment of the virtual machine platform and realizing effective management and control of communication between virtual domains.

Description

technical field [0001] The invention relates to a virtual machine platform, in particular to a trusted virtual machine platform. Background technique [0002] The current virtual machine platform includes: a common hardware platform, a virtual machine monitor, a privileged virtual machine (or host operating system) and several non-privileged virtual machines. However, the current virtual machine platform focuses more on functions than on security, which brings great security risks to upper-layer applications. First, the current virtual machine platform is implemented based on a common hardware platform and lacks hardware-level security protection. The physical root is not trusted, and the trustworthiness of the virtual domain cannot be guaranteed. Second, most of the current virtual machine platforms have not taken security protection measures. Although some have considered security, all security measures are based on software implementation, and the protection capabilities...
