Abstract

The invention relates to a virtual machine static measurement method and device based on a built-in safe architecture. The method comprises the steps of in the starting process of a physical host, enabling safe independent equipment to carry out safety measurement on a host machine system and virtualization software to ensure credibility of the host machine system and the virtualization software;enabling the host machine system and the virtualization software to determine a to-be-measured virtual machine core file; analyzing the virtual machine mirror image file, extracting the content of theto-be-measured virtual machine core file, performing security measurement on the content, and generating a measurement value; if judging that the virtual machine is started for the first time, indicating that the metric value serves as a reference value to be stored in the safe independent equipment, and the virtual machine is started; and if judging that the virtual machine is not started for the first time, verifying the metric value and a reference value in the safe independent equipment, cancelling starting of the virtual machine if verification fails, and starting the virtual machine ifverification succeeds. According to the invention, the extension of the static measurement mechanism of the virtual machine to the virtual machine can be realized, and the security of the virtual machine is enhanced.

Description

technical field [0001] The invention relates to the field of trusted computing, in particular to a method and device for static measurement of a virtual machine based on a security priority architecture. Background technique [0002] With the rapid development of informatization, cloud computing has gradually attracted people's attention, and more and more enterprises have deployed their production environments on cloud platforms. Cloud computing, a paid service model, allows enterprises to invest only with relatively low monthly fees, without the need for a one-time investment, and without taking up too much working capital, thereby alleviating the pressure of insufficient funds for enterprises; without considering cost depreciation issues, and Can obtain the latest hardware platform and the best solution in time. With the increase of users on the cloud, the security of the cloud platform has gradually become the focus of attention. In cloud computing, the security of clo...
