A survey of cryptographic algorithms for IoT devices

The future of Internet is “Internet of Things” where trillions of physical objects, most of them with low or extremely low resources, communicate with each other without human intervention. Light weight cryptography includes cryptographic algorithms specifically meant for extremely constrained resources. They can be applied not only for encryption but also for hashing and authentication under environments that are highly constrained. □ In this paper, we first discuss the need of light weight cryptography and their design differences with normal block ciphers. An overview of some of the light weight cryptographic algorithms is discussed after that. Also, we look into different types of attacks that has been studied on some of these ciphers. Finally, we compare the performance of some of these ciphers on Windows and Embedded platform.
