Design of Secure and Lightweight Authentication Protocol for Wearable Devices Environment

Area of Science:

• Computer Science
• Cybersecurity
• Wearable Technology

Background:

• Wearable devices collect vast amounts of sensitive personal data, necessitating robust security measures.
• Existing authentication schemes may not be suitable for the resource-constrained nature of wearable devices.

Purpose of the Study:

• To propose a novel, lightweight mutual authentication scheme for wearable devices and mobile terminals.
• To establish a secure session key for communication between user-worn and user-carried devices.

Main Methods:

• Development of a new authentication protocol.
• Security analysis using the real-or-random model.
• Formal verification using the Automated validation of Internet security protocols and applications (AVISPA) tool.
• Performance evaluation through NS2 simulations.

Main Results:

• The proposed scheme provides mutual authentication and session key establishment.
• Security analysis and formal verification confirm the scheme's robustness against common attacks.
• Comparative analysis shows favorable computation and communication overheads compared to existing schemes.

Conclusions:

• The developed lightweight authentication scheme is effective and efficient for securing data in wearable device ecosystems.
• This scheme enhances user privacy and data integrity in the rapidly growing field of wearable technology.
