Lightweight user authentication scheme for roaming service in GLOMONET with privacy preserving

Area of Science:

• Computer Science
• Network Security
• Information Technology

Background:

• Roaming services enable unrestricted user access across networks.
• Session key establishment between home and mobile nodes is crucial for roaming.
• Existing authentication methods in Global Mobility Network (GLOMONET) environments present security and privacy vulnerabilities.

Purpose of the Study:

• To identify vulnerabilities in current GLOMONET authentication schemes for roaming services.
• To propose a novel, lightweight authentication scheme addressing identified security and privacy gaps.
• To ensure non-traceability and protect user identity, passwords, and session keys.

Main Methods:

• Analysis of existing authentication schemes in GLOMONET.
• Development of a new lightweight authentication protocol.
• Formal and informal security analyses to validate the proposed scheme.

Main Results:

• The existing GLOMONET authentication scheme is shown to be vulnerable and impractical.
• The proposed scheme effectively addresses vulnerabilities related to session key privacy, user identity, and passwords.
• Security analyses confirm the proposed scheme's robustness and non-traceability.

Conclusions:

• The proposed lightweight authentication scheme is secure and practical for the GLOMONET environment.
• Enhanced privacy features, including non-traceability, are achieved.
• The new scheme offers a viable solution for secure and private mobile network roaming.
