A Security and Secrecy Method for Dynamic Parameter Wireless Test Network

Abstract

The invention discloses a dynamic parameter wireless test network security confidentiality keeping method. The method includes identity authentication and mutual authentication, acquired data interleaving processing, communication protocol encryption as well as test area frequency spectrum monitoring and positioning. A wireless test control center and a wireless test device use an identity authentication and mutual authentication scheme based on hardware feature codes and random authentication codes to avoid network access of illegal devices. An embedded processor of the test device performs interleaving operations on original data and constantly-updated dynamic interleaved sequences at each signal acquisition to complete data steganography. The air interface encryption is performed through encryption algorithms supported by the wireless communication technology protocol in the wireless test network. A wireless signal receiver is used for frequency spectrum monitoring and estimation of wave direction of the illegal devices in a dynamic parameter test area. The four security confidentiality keeping parts are designed in consideration of features of a dynamic parameter wireless test system to ensure the security of test data of the wireless test network.

Description

technical field [0001] The invention belongs to the technical field of testing, in particular to a security method for a dynamic parameter wireless testing network. Background technique [0002] At present, all aspects of human production and life are inseparable from testing technology. An obvious feature of modern testing technology is the use of electrical measurement. In the traditional electrical measurement method, a wired connection is used between the sensor for sensing physical parameters and the back-end signal conditioning acquisition and storage device. With the development of wireless communication technology and wireless sensor network, more and more low-frequency response parameter tests are currently used. Done wirelessly. Limited by factors such as test node energy and sampling rate, low-rate wireless sensor networks cannot be directly applied to the test of dynamic parameters. Dynamic parameter testing is generally used in processes such as explosion, des...

Problems solved by technology

The basic protocols of these communication methods also restrict security and confidentiality methods such as network access, data encryption, and identity authentication. However, these methods are designed for computers, mobile phones and other devices with operating systems and intelligent CPUs. Mainly, while the wireless test equipment used for dynamic parameter testing is mainly embedded equipment, using embedded processors such as FPGA, DSP, ARM, etc., without running the operating system, so the security method of the wireless communication network is directly transplanted to the wireless In the test network, there are problems such as complex algorithm implementation, limited computing resources, and the fact that the actual operating environment and the characteristics of the test equipment are not considered in the implementation process. app under test
