Enabling secure mutual authentication and storage checking in cloud-assisted IoT.

Area of Science:

• Computer Science
• Information Security
• Cloud Computing

Background:

• Internet of Things (IoT) devices generate vast amounts of data, often relying on cloud computing for storage and processing.
• Cloud environments face security challenges, including sophisticated attacks where adversaries impersonate legitimate IoT clients.
• Existing authentication mechanisms may not adequately protect cloud-assisted IoT systems against such threats.

Purpose of the Study:

• To propose a novel secure mutual authentication scheme for cloud-assisted Internet of Things (IoT) environments.
• To enhance the storage security of cloud systems by preventing unauthorized access.
• To introduce an efficient storage checking mechanism with improved fairness.

Main Methods:

• Development of a mutual authentication protocol utilizing chameleon hash signatures.
• Integration of a fully-trusted entity to facilitate storage checking.
• Rigorous security analysis to validate the proposed scheme's correctness.

Main Results:

• The proposed scheme successfully establishes mutual authentication between IoT devices and cloud servers.
• The use of chameleon hash signatures ensures the integrity and authenticity of communications.
• The integrated storage checking mechanism demonstrates high fairness and efficiency.

Conclusions:

• The presented secure mutual authentication scheme effectively addresses security vulnerabilities in cloud-assisted IoT systems.
• The scheme provides robust protection against impersonation attacks and enhances data storage security.
• The proposed solution offers a practical and efficient approach for securing cloud-IoT interactions.
