Embodiment

[0063] Implement the inventive method based on the x86 mainframe carrying the Linux-2.6.32 kernel version, the operating system uses the Ubantu operating system embedded in the TPM simulator, the trusted protocol stack TrouSerS, and compiles the functional modules of the inventive method into the kernel as an integrity measure module runs, and using this as an example, an integrity measurement framework embedded in the kernel such as figure 2 shown.

[0064] The measurement results of about 60-70 bash scripts and binary files were observed in the experiment, and the measurement list is as follows image 3 shown. The first row and the first column "10" in the figure indicate that the hash value of the measurement object and the index node is extended to the No. 10 register of the PCR, the second column "9202b189adcee134057a807610df110e5a71e36f" records the hash value of the object index node, and the third column "sha1 :5b9cf6a1cf1f454f53d15812b06b5691d9471809" records the s...

Abstract

The invention discloses a process behavior-based platform integrity state information measurement method. The method comprises the following steps of 1, capturing a measurement request of an application layer, and extracting a measurement object from an application; 2, analyzing a running state and an executive parameter of the application, and collecting process behavior information related to the measurement object; 3, according to a behavior characteristic, judging whether a current measurement result is added to a measurement list or not, and collecting the process behavior information related to the measurement object in the measurement list; 4, storing the measurement result in a specific PCR of a trusted platform module through expansion operation, generating a measurement report and sending the measurement report to a log audit mechanism of the application layer; and 5, according to the measurement list, a measurement log and the measurement result stored in the PCR, verifyingand calculating integrity state information of the platform. According to the higher-granularity integrity state information measurement method provided by the invention, the reflected to-be-verifiedand calculated security attribute information of the platform is more accurate, so that the measurement efficiency can be improved.

Description

technical field [0001] The invention belongs to the fields of trusted computing and remote certification, in particular to a method for measuring platform integrity state information based on process behavior information. Background technique [0002] With the rapid popularization of Internet applications, people use them more and more widely in daily life. Due to the open interconnection of the Internet, many unsafe factors have been added at the same time, such as viruses, worms, and Trojan horses. They attack terminals through vulnerabilities and seriously threaten computer security. For example, the Petya ransomware virus and its variants that have swept across more than 150 countries around the world since June 2017. This type of virus can spread through emails, program Trojan horses, etc., and attack by using DOC files with vulnerabilities. After poisoning, the virus will modify the MBR boot sector of the system, encrypt the NTFS partition, and prevent the machine fro...
