20090288161 | METHOD FOR ESTABLISHING A TRUSTED RUNNING ENVIRONMENT IN THE COMPUTER - The present invention discloses a method for establishing a trusted running environment in a computer. A trusted file authentication module and a trusted process memory code authentication module are preset in operation system (OS) of the computer and a secured OS is loaded and run. The trusted file authentication module intercepts all file operation behaviors, checks whether current file to be operated is a trusted file or not, and processes the file according to its operation type if it is trusted, otherwise processes the file after its eligibility is verified; the trusted process memory code authentication module authenticates on timing whether the running state and the integrality for all process code are normal or not; if any process is abnormal, giving an alarm, saving field data run by the process and closing down the process; otherwise continuing to run normally. With this invention, the security for the running environment in the computer can be ensured whether the attack from known or unknown virus exists or not, and this facilitates application and reduces implementation cost. | 11-19-2009 |
