Abstract: The Trivial File Transfer Protocol (TFTP) has received remarkable attention as a significant medium for transferring information on embedded Machine-to-Machine (M2M) system due to its lightweight features and compatibility. However, major limitation is the lack of security feature where its reliability is questionable, especially during the process of data collection and system update. Therefore, to strengthen TFTP communication protocol, a new key exchange technique based on well-known Diffie Hellman Key Exchange (DHKE) algorithm is proposed to generate a shared secret key. The proposed technique is integrated with TFTP packet header for optimal solution to provide a secure TFTP communication in M2M technology. In this research, simulation of TFTP packet transmission is performed using NS3 as an initial finding for security support in the protocol. This research makes major contribution which has potential to enhance TFTP capability in constrained M2M communication field.
