Evaluation of the parameters of the simulation model of microcontroller authenticators

Abstract

Microcontroller technologies are the basis for intelligent devices, so cybersecurity issues are important when ensuring the exchange of information between them. As these devices form a variety of intelligent systems, authentication becomes a key aspect of cybersecurity. This process distinguishes between legitimate and illegitimate devices, allowing legitimate devices to access system resources and reject requests from illegitimate ones. Today there is a problem of choosing an authentication factor for a large number of electronic devices of the same type in the information system. The purpose of this study is to find out the possibility of a programmatic approach to simulating a "biometric" authentication template. To solve the goal, it is necessary to implement a simulator of templates with the properties of biometrics in a programming language, to evaluate the distribution of distances between pairs of templates, and to evaluate the parameters of the generated sequences from the point of view of brute force probability. In this study, a solution to the problem is proposed, which combines the ideas of the biometric factor and the possibilities of fast software generation of authenticators for microcontrollers. The work is devoted to the evaluation of the model parameters of the simulator of dynamic bit patterns of authentication based on the generator of pseudo-random impulse Poisson sequences. The work highlights the basic principles of the simulator's functioning and the advantages of using dynamic templates to ensure cyber security of electronic devices built on the basis of microcontrollers. Estimates of the main parameters of the simulator model were performed. The results of the work are important for the development of security of electronic systems and means of authentication in the context of cybersecurity of microcontrollers.
