Abstract

Embodiments of the present invention provide an integrity verification method and device. In this embodiment of the present invention, the first device sends a first request message for acquiring the comprehensive metric value to the second device. The second device carries the comprehensive measurement value and measurement times of the second device in the returned first response packet. The first device sends, to the second device, a second request message for acquiring the log records of the number of metrics. The second device carries the metric number of log records in the second response packet returned by the second device. The second device verifies the integrity of the second device according to the obtained metric times and log records and the comprehensive metric value. In the embodiment of the present invention, the number of interactions between devices is small, which can effectively improve the efficiency of integrity proof.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an integrity proof method and device. Background technique [0002] Trusted computing establishes a specific integrity measurement mechanism to verify whether network devices are attacked by malicious code. This verification process is also known as integrity proof. [0003] The network device measures the program code running on the device, and notifies the measurement-related information to the peer device, so that the peer device can verify the integrity of the device. [0004] The information exchange process of integrity proof is as follows: figure 1 shown. Here, taking the device 12 to verify the integrity of the device 11 as an example, the interaction process includes: [0005] Step 101, the device 12 requests to obtain the measurement log of the device 11; [0006] Step 102, the device 11 returns the measurement log of the device to the device 12, whic...
