Multilayered Architecture for Secure Communication and Transmission for Internet of Things

The Internet of things (IoT) is a worldwide network of objects equipped with controllers, sensors, and software that can collect, process, and exchange data, and whose operation is dependent on interactions between subsist or recently developed information and communication technologies. The Internet of things facing the basic privacy and security risks as well as latest security issues and risks. To improve the network structure of Internet of things, a new multilayers security architecture is proposed, and the aim of this architecture is to discuss or implement the security element on each of the layer of IoT architecture. A multilayered IoT architecture with security mechanisms is necessary to identify physical objects, set their operation rules, safeguard outbound off the record information, assure the integrity of data acquired, and reduce energy usage. The representatives in the IoT smart environment communicate with one another using application layer protocols, which make certain that information is accessible to authorized users and that messages delivered between them are reliable.
