A lightweight and secure protocol for teleworking environment.

Area of Science:

• Computer Science
• Cybersecurity
• Network Security

Background:

• Teleworking systems offer convenience but are vulnerable to various security threats.
• Existing security mechanisms for teleworking systems are insufficient to address all identified vulnerabilities.
• A lack of secure authentication is a critical security issue in current teleworking environments.

Purpose of the Study:

• To propose a lightweight and secure protocol for authenticating participants in teleworking systems.
• To ensure efficient and secure access to requisite services within teleworking environments.
• To address identified security issues including insider threats, stolen verifiers, masquerade, replay, traceability, and impersonation.

Main Methods:

• Formal security analysis using the random oracle model (ROM).
• Security verification through ProVerif simulation.
• Informal security analysis via illustration and attack discussions.
• Performance evaluation based on computation and communication overheads.

Main Results:

• The proposed protocol provides a secure authentication mechanism for teleworking systems.
• Formal and informal analyses confirm the protocol's robustness against various attacks.
• Performance metrics show a 73% improvement in computation costs and a 34% improvement in communication costs compared to prior works.

Conclusions:

• The developed protocol offers a superior and efficient solution for securing teleworking environments.
• The protocol's suitability for implementation is demonstrated through significant performance enhancements.
• This research contributes to a more secure and reliable teleworking infrastructure.
