A CoAP-Based Network Access Authentication Service for Low-Power Wide Area Networks: LO-CoAP-EAP

Area of Science:

• Internet of Things (IoT) security
• Wireless networking protocols
• Network access authentication

Background:

• Low-Power Wide Area Networks (LP-WAN) enable long-range, low-energy IoT communication but face bandwidth limitations.
• Network access authentication is crucial for IoT resource management but current LP-WAN solutions lack interoperability.
• Existing authentication methods are often technology-specific, hindering seamless integration across different LP-WANs.

Purpose of the Study:

• To propose a wireless-independent network access authentication solution for LP-WAN environments.
• To address the challenge of interoperability issues in current LP-WAN authentication mechanisms.
• To enhance security and manageability for diverse IoT applications utilizing LP-WAN.

Main Methods:

• Developed Low-Overhead CoAP-EAP (LO-COAP-EAP), a service building upon prior work for Low-Rate Wireless Personal Area Networks (LR-WPAN).
• Integrated Authentication, Authorization and Accounting (AAA) infrastructures with the Extensible Authentication Protocol (EAP).
• Utilized the Constrained Application Protocol (CoAP) to create a technology-agnostic network authentication service.

Main Results:

• LO-COAP-EAP provides a unified approach to network access authentication for various LP-WAN technologies.
• The proposed service demonstrates a balance between flexibility, wireless independence, scalability, and performance.
• Successfully established a foundation for interoperable authentication services in the expanding LP-WAN landscape.

Conclusions:

• LO-COAP-EAP effectively fills the gap for wireless-independent authentication in LP-WANs.
• The solution promotes enhanced security and interoperability, crucial for the future growth of IoT.
• This approach offers a scalable and performant trade-off for managing network access in constrained environments.
