Embedded systems play a critical role in various applications, where software and hardware work together to perform dedicated tasks. Their constrained nature, involving factors like power, size, and performance, presents significant security challenges. As the demand for more functionality in smaller devices rises, security often takes a backseat. This paper addresses the increasing vulnerability of embedded systems to attacks and emphasizes the need for robust security measures. It presents the development of a secure communication method for embedded devices and offers comparisons of available open-source tools.
