Abstract
Internet of things (IoT) is a rapidly emerging architecture connecting smart devices all across the world in various fields like smart homes, smart cities, health sector, security, etc. Security is a very important aspect of IoT. As more and more devices are connecting to the Internet, it becomes a lucrative target for hackers. The communication between the various devices, nodes, and between nodes and the cloud, needs to be secured. A combination of public and private key cryptography systems is used to secure the IoT networks. The Advanced Encryption Standard (AES) is used for encrypting the data in transit. However, the AES is known to be prone to brute force attacks, side channel attacks, and other forms of cryptanalysis. This chapter proposes a more secure AES algorithm with randomised round keys, which provides better security with negligible overheads, and is ideal for use in IoT networks.
