Modelling the Hybrid Security Approach for Secure Data Exchange: A Proof of Concept

Abstract

The importance of secure data transfer for operational efficiency is undeniable. This study explores a novel approach to securing communication protocols by combining the established Diffie-Hellman key exchange method with the popular AES encryption algorithm. A practical demonstration (Proof of Concept) showcases the effectiveness of this method in safeguarding data against unauthorized access and impersonation during transmission, particularly within the resource-efficient Trivial File Transfer Protocol (TFTP) used by devices with limited capabilities. This research proposes an innovative secure file transfer protocol that utilizes multiple cryptographic techniques to strengthen data transmission in Machine-to-Machine (M2M) communication. This enhanced security has the potential to make TFTP a reliable option for managing and upgrading low-cost embedded systems, particularly in environments susceptible to security threats.
