Advanced Attacks and Protection Mechanisms in IoT Devices and Networks

In the past decade, the Internet of Things (IoT) has emerged as a wonder‐pill to our problems. This chapter gives an overview of physical security threats and protection mechanisms of low‐end IoT devices, focusing on side‐channel analysis (SCA) and fault analysis attacks. It concentrates on remote attestation (RA) techniques, that aim at detecting malicious changes in the device’s firmware by requesting a proof to verify the sanity of the device. RA is a security protocol that runs between a trusted party called Verifier and “potentially” untrusted party called Prover. Primarily, RA techniques can be subdivided into three main categories: software‐based RA; hardware‐based RA, and hybrid architecture‐based RA. The chapter discusses challenges that IoT malware poses on IoT systems and introduces state‐of‐the‐art intrusion detection approaches for IoT networks for coping with such threats.
