With the advent of the Internet of Things (IoT) where anything can communicate, several security, privacy, and intimacy concerns arise. Introducing tiny and invisible devices that can exchange data inside and outside our homes, cars, and even bodies constitute a major threat. This book gives a comprehensive Tutorial on IoT security and privacy issues, with particular focus on standard architectures, emerging architectures, and state of the art technologies. The book covers all available IoT technologies, not only those based on IETF standards, and helps the reader get a full picture of the state of the art without the burden of going through the details of standard documents and the myriad of web sites dealing with IoT. This book can be of great help for instructors and new researchers in the area.
