"IoT" (Internet of Things), "IIoT" (Industrial Internet of Things), "CPS" (Cyber-Physical Systems) are the common terms that are used to describe the ecosystem of these "smart things". This chapter focuses on security issues within IoT devices in a smart home environment. It aims to study authentication mechanisms in smart home systems with a focus on mutual authentication as a solution to improve the security posture of smart home devices. The chapter gives an overview of a smart connected home system, security issues and solutions in smart devices, a primer on mutual Transport Layer Security, key management practices, mutual authentication in smart home systems and its challenges as well as open research items. Three categories of mutual authentication occur: between the user and the gateway, between the gateway and the smart devices, between the user and the smart devices.
