A virtualization system and method based on xen secure computer trusted device

Abstract

The invention belongs to the application field of virtualization technology, and in particular relates to a virtualization system and method based on a Xen secure computer trusted device. The system includes a virtual trusted device, and the virtual trusted device includes a trusted device virtualization back-end driver, a trusted device virtualization front-end driver and a trusted back-end management module; the trusted device virtualization front-end driver is set in the virtual client system In the virtual client system, there is also an application program, and the application program is connected to the trusted device virtualization back-end driver set in the privileged domain operating system through the trusted device virtualization front-end driver; the trusted back-end management module is set in the privileged domain In the domain operating system, it is connected with the trusted device virtualization back-end driver and the hardware trusted device. The invention provides trusted device services for the virtual client system under the condition of ensuring the credibility of the virtual client operating system, relieves the dependence of the original trusted device virtualization technology on the trusted device simulation tool, and realizes the domestic trusted device virtualization.

Description

technical field [0001] The invention belongs to the application field of virtualization technology, and in particular relates to a virtualization system and method of a Xen-based secure computer trusted device. Background technique [0002] With the rapid development and wide application of computer and network technology, the degree of global informatization continues to increase. Information security is not only inseparable from our daily life, but also directly affects national security, economic development and social stability. Especially in recent years, the country implements the information system hierarchical protection policy, and the demand for computer security functions is very urgent. [0003] In order to solve the problem of information security, countries and enterprises are formulating relevant laws, regulations and systems to protect their own information security. Domestic and foreign software development companies have developed targeted anti-virus softw...

Problems solved by technology

[0005] However, on the one hand, although the security computer improves the security of the system to a certain extent, it does not guarantee the security of the virtual guest operating system that directly interacts with ordinary users; on the other hand, the original trusted device virtualization technology relies on Because of the trusted device emulation tool (tpm_emulator), it is not easy to expand and update, and it is impossible to realize the virtualization of domestic trusted devices in the same way
