A Collaborative Lightweight Scheme for Secured Key Establishment using Heuristic Algorithm for Internet of Things

The Internet of Things (IoT) is a popular field that integrates physical world with internet for increasing the efficiency of data usage by the owners. The physical devices connected through IoT are embedding with software, electronics, sensors and actuators to cloud. There are several protocols available to provide device communication with reduced bandwidth and delay requirements. Such communication between IoT devices should be protected using security mechanisms that should ensure secured key distribution across the network. In this paper, we propose a collaborative key management system with a novel framework that ensures better selection of optimal proxies and that ensures secured cryptographic actions until the completion of encryption action. The framework consists of automated key establishment using bat algorithm and fuzzy neural network, where former optimally selects the proxies using cryptographic actions and latter generates automated key by considering computational burden and memory requirement as its concern. The results shows that the proposed collaborative lightweight scheme obtains improved efficiency than other systems.
