A Secure IoT-Based Authentication System in Cloud Computing Environment

Area of Science:

• Computer Science
• Cybersecurity
• Network Engineering

Background:

• The Internet of Things (IoT) is a rapidly growing field, but secure authentication remains a significant challenge.
• Previous authentication schemes for IoT have been shown to be vulnerable to various attacks, including offline guessing and user tracking.
• A recent lightweight authentication scheme for IoT was proposed but found to have weaknesses.

Purpose of the Study:

• To address the identified security weaknesses in a recently proposed lightweight IoT authentication scheme.
• To propose an enhanced authentication scheme that improves security and reliability for IoT environments.
• To ensure the enhanced scheme can resist known attacks and provide essential security features.

Main Methods:

• Analysis and evaluation of an existing lightweight IoT authentication scheme.
• Development of an enhanced authentication mechanism based on the original scheme's principles.
• Security analysis to verify the proposed scheme's resilience against various cyber threats.

Main Results:

• The proposed enhanced scheme effectively addresses the identified vulnerabilities in the prior IoT authentication mechanism.
• The enhanced scheme demonstrates robustness against common attacks such as offline guessing and user tracking.
• Key security features including mutual authentication, user audit, and session security are successfully implemented.

Conclusions:

• The enhanced authentication scheme provides a more secure and reliable solution for IoT architectures.
• The proposed mechanism successfully meets the security requirements for modern IoT applications.
• This work contributes to the ongoing effort to secure the Internet of Things.
