Trust Management in the Internet of Things

Abstract

The internet of things (IoT) is a new paradigm where users, objects, and any things are interconnected using wired and wireless technology such as RFID, ZigBee, WSN, NFC, Bluetooth, GPRS, and LTE. In this last decade, the IoT concept has attracted significant attention from both industrial and research communities. Many application domains may have significant benefits with IoT systems. These domains range from home automation, environmental monitoring, healthcare, to logistic and smart grid. Nevertheless, the IoT is facing many security issues such as authentication, key management, identification, availability, privacy, and trust management. Indeed, establishing trust relationships between nodes in IoT represents a primary security milestone to have reliable systems that exclude malicious nodes. However, trust management in an IoT constrained and ubiquitous environment represents a real challenge. This chapter presents an overview of trust management in IoT. This overview explains and demonstrates the usefulness of trust management and how it should be exploited in IoT.
