Authentication Systems in Internet of Things

TL;DR

This paper reviews various authentication systems for IoT, including MFA, OAuth, and delegation-based methods, highlighting their mechanisms and security implications.

Contribution

It provides a comprehensive analysis of existing authentication protocols tailored for IoT, emphasizing their applicability and security features.

Findings

MFA offers strong security but is less applicable to IoT.

OAuth facilitates third-party access to IoT resources.

Delegation-based authentication suits IP-based IoT environments.

Abstract

This paper analyses the various authentication systems implemented for enhanced security and private re-position of an individual's log-in credentials. The first part of the paper describes the multi-factor authentication (MFA) systems, which, though not applicable to the field of Internet of Things, provides great security to a user's credentials. MFA is followed by a brief description of the working mechanism of interaction of third party clients with private resources over the OAuth protocol framework and a study of the delegation based authentication system in IP-based IoT.
