Securing Internet-of-Things

In this survey, we first present some vulnerabilities and attacks on IoT systems, and classification of IoT devices, we then show the evolution of the development of lightweight cryptography for securing IoT, the metrics for the design of lightweight cryptography, and the applications in privacy preserving authentication protocols. We use examples including the development of Simon, Simeck, and sLiSCP/sLiSCP-Light lightweight ciphers to demonstrate those approaches.
