A Secured Multi-Stages Authentication Protocol for IoT Devices

Abstract

The Internet of Things (IoT) facilitates the deployment of sensing devices for data acquisition and transmission across networks and systems, thus enabling innovative real-time applications.Securing these platforms remains paramount due to the high value placed on data privacy.This study proposes a novel real-time authentication method, fundamentally grounded in a One-Time Pad (OTP) concept.Data are encrypted using dynamic encryption, the parameters of which are determined by data from randomly distributed sensors.Encryption keys are dynamically transmitted, allowing for on-the-fly key generation and exchange.This enhances the security and privacy of user data.A lightweight technique for key creation, exchange, and authentication is presented for data collection from sensors used in real-time applications.This protocol ensures data privacy and security throughout the data collection process.The proposed protocol's efficacy is demonstrated through a discussion of how it meets these criteria, and an example illustrating its operation at each tier in the event of desynchronization or an incident.
