Real-Time Authentication of Electronic Devices in Cyber-Physical Systems

The paper presents the results of experimental studies to determine the authentication characteristics of electronic devices. There are given the calculation of the authentication template based on internal electrical noise and the assessment of the authentication effectiveness. Discrete autocorrelation function of internal electrical noise is used for definition identification signs. An automatic authentication system based on the client-server architecture is proposed. The system operates in real time and consists of several software modules. The authentication system is implemented at the software level, an additional device does not require. The system is scalable; its operation does not depend on the channel of information transfer between the device and the server. The proposed system can be used for continuous inventory of electronic devices of a cyber-physical system.
