Підвищення захисту від НСД до програмних кодів мікроконтролерів систем безпеки

Abstract

This master's thesis deals with the problem of increasing protection against unauthorized access to the software codes of microcontrollers of security systems. The main task of this work is to develop methods to enhance the protection of software codes of microcontrollers, which are the basis of security systems. This work analyzed the domain, identified the attacks that create the risk of unauthorized access to the software codes of the microcontrollers, as well as existing methods of countering these attacks. The choice of microcontrollers for protection development is justified. Protection for selected ATMega and STM32 microcontrollers has been developed. The practical implementation of the developed security elements for the selected microcontrollers was also carried out.
