Title: METHOD AND APPARATUS FOR REALISING INTEGRITY PROTECTION FOR OPERATING SYSTEM
Abstract:
A method and apparatus for realising integrity protection for an operating system. The method comprises: a trusted control core module acquiring metric values corresponding to one or more metric parameters of a monitored operation behaviour in a protected operating system and/or a virtual machine monitoring module, and sending the obtained metric values of all the metric parameters to a trusted metric module; the trusted metric module acquiring reference metric values of all the metric parameters from a trusted reference library module, determining that the metric values of the one or more metric parameters are different from the corresponding reference metrics, and sending, to the trusted control core module, information representing the prevention of the monitored operation behaviour; and the trusted control core module preventing the monitored operation behaviour and/or recording the monitored operation behaviour. The trusted control core module is arranged in the virtual machine monitoring module, and the virtual machine monitoring module, the trusted metric module and the trusted reference library module are arranged outside the protected operating system.
