Embodiment Construction

[0041] First, the architecture of the communication system to which the method for proving a trusted state provided by the present application is applied is described. Figure 1 is a schematic diagram of the communication architecture of the application of the trusted state attestation method. like figure 1 As shown, the communication system includes a certification server 101 and a network device cluster 102. The network device cluster 102 includes multiple network devices. The certification server 101 is connected to each network device. The interconnected certification servers 101 exchange information with the network devices, so as to realize the certification of the trusted state of each network device. The connection mode between the certification server 101 and each network device will be described below with reference to specific examples.

[0042] For example, the network device 1021 included in the network device cluster 102 is directly connected to the certificat...

Abstract

The embodiment of the invention discloses a trusted state certification method and related equipment, which are used to reduce the amount of information to be processed by the certification server and the burden of the certification server in the process of certification of the trusted status. The method in the embodiment of the present invention includes: firstly, measuring the first trusted certification agent of the network device to obtain the first proxy metric value; then, sending the first proxy metric value to the upstream device; finally, receiving the first proxy metric value from the upstream device; At least one baseline value of the device, at least a portion of the at least one baseline value is used to demonstrate the trusted status of the downstream network device.

Description

technical field [0001] The present application relates to the technical field of network security, and in particular, to a method and related equipment for proving a trusted state. Background technique [0002] In order to solve the current network security problems, the trusted computing group (TCG) proposed a method of trusted computing. Through the trusted computing method, it can be proved whether the network equipment is illegally tampered with and destroyed. [0003] However, with the increasing complexity of networking, it proves that the server is connected to a large number of network devices. The certification of the trusted state of a large number of network devices needs to rely on the certification server. Thus, the amount of information that needs to be processed and the burden of the attestation server are increased in the process of the attestation server performing the trusted state attestation. If it is proved that the server has been illegally tampered ...
