A Review on IoT Security Architecture: Attacks, Protocols, Trust Management Issues, and Elliptic Curve Cryptography

Abstract

Internet of Things has become popular for the industrial and commercial environment and also for research purpose by providing a large number of applications that facilitate human daily and social life more comprehensible and convenient. Internet of Things amalgamates various kinds of sensors, actuators, and physical object to communicate with each other directly even in the absence of a human. For the formation of the IoT-equipped devices and network, security and trust among various parties are major concerns. Here, we discuss the security and privacy available at each layer of the IoT model and also the limitation and future direction that can be implemented to enhance IoT security architecture. However, trustworthy channel must be necessary for secure communication, and here, we also discuss elliptic curve light-weighted encryption technology used for trust management in IoT.
