Internet of Things equipment identity certificate generation method based on network traffic feature fusion

Abstract

The invention provides an Internet of Things device certificate generation method based on network traffic feature fusion, and belongs to the technical field of Internet of Things device identity recognition. The method comprises the following steps: firstly, constructing a fingerprint feature set related to equipment identity recognition from three dimensions of equipment network protocol stack fingerprint features, equipment network data sequence features and equipment network data protocol features; screening the features by using the features and the related features between the terminalsto obtain an optimal feature set; and finally, carrying out dimension reduction processing on the feature subset by adopting a principal component analysis method, eliminating redundant features of feature data, and generating a terminal fingerprint certificate. According to the invention, the credentials required by the admission credentials required by equipment recognition can be extracted fromthe network flow data of the Internet of Things equipment, and the credentials are related to the physical characteristics of the Internet of Things equipment, so that counterfeit equipment can be effectively identified.

Description

technical field [0001] The invention belongs to the technical field of access control of Internet of Things devices, and in particular relates to a method for generating certificates of Internet of Things devices based on fusion of network traffic characteristics. Background technique [0002] Existing IoT terminal devices have security issues such as identity authentication and access control when devices are connected. Traditional identity authentication technology needs to realize unique identity identification and legality judgment based on identity certificates, which requires the deployment of identity certificates on all legal terminal devices. Since most terminals cannot provide identity certificates in the form of hardware or certificates to realize identity recognition functions, and there are various types of terminals, a large number, different platforms, and closed software and hardware environments, it is not feasible to realize unified identity certificates in...
