Secure and Efficient Lightweight Key Distribution Protocol (LKDP) for IoT Networks.

The Internet of Things (IoT) plays a crucial role in ensuring secure device-to- device (D2D) interactions due to its ability to interconnect vast numbers of smart devices in real-time. In IoT ecosystems, devices often communicate directly without human intervention, creating opportunities for malicious activities like unauthorized access, data tampering, or eavesdropping. However, the restricted compute, memory, and energy capacities of devices provide a number of difficulties for key distribution in lightweight cryptography for the Internet of Things and other resource-constrained situations. The paper therefore proposes a novel dimension to key distribution, the Lightweight Key Distribution Protocol for IoT devices. The protocol presented is not only secure against many attack instances but also efficiently scalable to adaptable IoT networks, it also complies with current and future standards. In this paper, LKDP-IoT demonstrated that, via the complementation of theory and practical test deployment, it is a novel but significantly superior solution when securing communication, over IoT in comparison to other existing solutions. It could be considered that the arrival of LKDP-IoT is a move forward in providing reliable and secure solutions for Internet of Things.
