IoT Security

Abstract

The usage of the internet of things (IoT) devices is growing for the ease of life. From smart homes to smart cars, from smart transportation to smart cities, from smart hospitals to smart highways, these IoT devices send and receive highly sensitive data regarding the privacy of users or other information regarding the movement of users from one location to another location. The timing traces users when present at home and out of the home. But how does one secure this information from the attacker? There is a need for IoT devices security. As there are three layers of IoT devices—the application layer, network layer, and perception layer—three layers to be secure. IoT devices are heterogeneous and constrain energy consumption. The proposed solution in this chapter is three-way authentication of IoT devices by generating tokens from the device serial number and from the few configuration devices at the network layer. For high availability of IoT device services, the protection against distributed denial of service attack is implemented at the network layer.
