A Study and Comparison of Cryptographic Mechanisms on Data Communication in Internet of Things (IoT) Network and Devices

A trending topic that has grown in prominence over the past several years is the Internet of Things (IoT). With the steadily increasing adoption rate of Internet-enabled devices in applications like smart homes, smart cities, smart grids, and healthcare applications, the demand of IoT becomes increasing. Now this needs to guarantee the safety of data and communications privacy among these IoT devices and their supporting infrastructure. IoT involves numerous low-resource devices, and most of these devices often need to secure interaction with their network administrators, which are IoT network nodes with more resources. Even though more services and applications are being connected through wireless network, security is still a major concern. IoT system security is a subject that is actively being researched. In this research paper, we discussed and contrasted the various network-based IoT authentication and communication security techniques. Few key points are also discussed regarding the IoT challenges and popular IoT cryptography approaches along with lightweight cryptography and trends in IoT.
