A lightweight and secure two factor anonymous authentication protocol for Global Mobility Networks

Area of Science:

• Wireless Communication Security
• Network Authentication Protocols
• Global Mobility Networks (GLOMONETs)

Background:

• Global roaming services rely on Global Mobility Networks (GLOMONETs) for seamless international mobile access.
• Advancements in wireless technology introduce new security threats, necessitating robust authentication protocols.
• Existing authentication schemes, such as Lee et al.'s, have demonstrated vulnerabilities including lack of anonymity and susceptibility to attacks.

Purpose of the Study:

• To identify and address the security flaws in Lee et al.'s authentication protocol for GLOMONETs.
• To propose a novel, robust, and anonymous authentication scheme for wireless communication.
• To enhance user authentication efficiency and security against various cyber threats.

Main Methods:

• Critical analysis of Lee et al.'s authentication protocol to identify weaknesses.
• Design and development of a new anonymous authentication scheme.
• Formal verification of the proposed protocol using the ProVerif automated tool.

Main Results:

• The proposed scheme effectively addresses identified vulnerabilities in Lee et al.'s protocol, including anonymity, authentication efficiency, replay, DoS attacks, and local password verification.
• Formal verification confirms the security and robustness of the proposed anonymous authentication protocol.
• The new protocol demonstrates superior efficiency compared to existing authentication schemes.

Conclusions:

• The developed anonymous authentication scheme provides a more secure and efficient solution for GLOMONETs.
• The findings contribute to strengthening security in global wireless roaming services.
• The proposed protocol offers a viable alternative for secure authentication in wireless communication environments.
