An efficient lightweight key exchange algorithm for internet of things applications

<p><span>Internet of things (IoT) gained wide popularity in recent years, and this is proved by tremendous increase use IoT applications worldwide. Distributed can be implemented securely with the support blockchain. By default, blockchain will ensure authentication involved entities as well integrity data. Due to storage restrictions, hybrid system preferred, involves cloud server for other functionalities. Data kept has encrypted a strong encryption algorithm. Even though core security objectives are achieved, it necessary provide secure method exchange key. Since, key backbone algorithm, protection ensured. In work, an algorithm proposed no-share between two communicating parties resource constrained environment. The same was compared conventional sharing algorithms. Security analysis formally conducted using widely accepted automated validation internet protocols (AVISPA) tool secure.</span></p>
