A Comparative Study on the Different Attacks IOT: The Perception Layer

The paradigm of the Internet of Things (IoT) is one of the most exciting innovations of recent years. However with each connected object the number of possible attacks will increase exponentially. This article presents a comparative study between the different solutions against the attacks of the Iot, we will first present a security architecture that we can divide it into 3 main layers perception layer, network layer, and layer of application. Each layer is divided by hierarchies that guarantee security, namely confidentiality, integrity, authenticity, and data acquisition, and then we focus on the attacks of the perception layer, which is extremely vulnerable to security attacks while classifying these attacks on both wireless technologies (WSN, RFID). Finally We discuss about the different approaches provided against these attacks Keywords - IOT attacks , security, WSN, RFID
