A productive key distribution method for the IoT technology.

Our lives have significantly transformed as a result of the Internet of Things (IoT). We employ IoT because of our customers, government agencies, and business partners. Security is a major problem when offering a variety of services even if IoT offers new options. Particularly hard is how the statistics are presented. How to secure the flow of information produced by IoT devices while passing through various nodes and gateways may be safeguarded from security threats. In this paper, we propose an effective key management approach that mixes symmetric and asymmetric cryptosystems in order to get the speed of the former and the security benefits of the latter. Our aim is to guarantee the IoT environment's security. Our method takes into account a number of Smart Objects (SO) that can produce, register, and distribute keys for IoT information transfer. We selected the open-source MessageQueuingTelemetryTransport (MQTT) protocol as a solution to help communication between the starting point and target nodes. The proposed approach is tested experimentally, and the results are discussed in terms of key exchange time, algorithm implementation time, number of reprocess connections, and bandwidth consumption.
