Embodiment Construction

[0060] In order to make the purpose, technical solution and advantages of the present invention clearer, the method for measuring the dynamic integrity of the trusted kernel of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0061] Such as figure 1 As shown, a trusted kernel dynamic integrity measurement method includes the following steps:

[0062] S100, by operating the white list of the memory file system configuration file, the policy cache and the status of the measurement server;

[0063] S200, performing measurement processing on the file,

[0064] S300, judging whether the execution program in the operating memory file system is modified, if it is entered into S500, if not entered into S400;

[0065] S400, program execution or process r...

Abstract

The invention provides a reliable core dynamic integrity measuring method which includes: configuring the states of a white list, strategy cache and a measuring server; and conducting measuring service which includes that whether an executive program or progress is successful is judged, on yes judgment, the program is executed or the progress is operated, and on no judgment, the program is not executed or the progress is not operated. Configuration and management of users are conducted through a memory file system, and users can look up and set core service and cache state and information conveniently. The measuring work of the integrity is finished through a core, so that the reliable core dynamic integrity measuring method is convenient to configure and manage and safe in measuring structure and measuring progress. The users can use the method simply and have good experience.

Description

technical field [0001] The invention relates to the field of trusted computing, in particular to a method for measuring the dynamic integrity of a trusted kernel. Background technique [0002] With the continuous advancement of science and technology and the continuous improvement of applied information technology, the use of trusted computing in computing and communication systems is becoming more and more extensive. Trust metrics are the key technologies of trusted computing, used to measure and evaluate system expectations The degree of conformity between the description and the actual behavior of the system plays an important supporting role in the construction of the trust chain and remote certification of the trusted computing platform. [0003] Currently, there are two trust measurement methods in the prior art: one is an integrity measurement architecture based on a Linux operating system and a TPM hardware chip, referred to as IMA. One is to improve the defect of I...
