IoT Service Layer Protocols & Security Protocols

I. Introduction

The Internet of Things (IoT) is a network of interconnected devices that communicate and exchange data with each other. In order to facilitate this communication, IoT relies on various protocols at different layers of the architecture. Two important layers in IoT are the service layer and the security layer. In this topic, we will explore the fundamentals of IoT service layer protocols and security protocols.

A. Importance of IoT Service Layer Protocols & Security Protocols

The service layer protocols in IoT are responsible for enabling interoperability and communication between different devices and applications. They provide a standardized way of exchanging data and commands, making it easier for devices from different manufacturers to work together. On the other hand, security protocols ensure the confidentiality, integrity, and availability of data in IoT systems. They protect against unauthorized access, data breaches, and other security threats.
