Cryptography and Security in Internet of Things (IoTs): Models, Schemes, and Implementations

Internet of Things (IoT) has attracted the interest of the research community, at a great manner the last years. It is one of the most hot topics, for current and future research areas, involved by both academia and industry sectors. Security and privacy issues for IoT are proven targets of great importance. This tutorial brings together models, schemes and implementation aspects, regarding the alternative technologies and devices of IoT. It focusses on the knowledge of the implementation efficiency, basically in hardware aspects, of communications confidentiality, user authentication, data integrity and services availability. Attacks and modern threats, as well as to countermeasures against them, are considered. Different IoT infrastructures are presented and alternative trust models are illustrated. Policy issues are also discussed.
