A Comprehensive Analysis: Evaluating Security Characteristics of Xbee Devices against Zigbee Protocol

Area of Science:

• Cybersecurity
• Wireless Sensor Networks
• Internet of Things (IoT)

Background:

• Sensor network security is critical, particularly for IoT applications.
• Zigbee protocol is widely used in wireless sensor networks.
• Xbee devices by Digi International are popular Zigbee implementations.

Purpose of the Study:

• To analyze the security features of Xbee 3 devices concerning the Zigbee protocol.
• To identify vulnerabilities and strengths in Xbee 3 security configurations.
• To propose enhanced security measures for Zigbee networks.

Main Methods:

• Real-time packet interception and analysis using Wireshark.
• Investigation of network formation, packet transmission, and security key usage.
• Evaluation of security in scenarios without security, distributed, and centralized modes.

Main Results:

• Xbee 3 devices exhibit security differences compared to the standard Zigbee protocol.
• Preconfigured global link keys in Xbee 3 devices present a significant vulnerability.
• Devices are susceptible to man-in-the-middle and replay attacks due to identified weaknesses.

Conclusions:

• Xbee 3 security features require careful consideration due to inherent vulnerabilities.
• Current security key establishment methods need validation and potential revision.
• Future research should explore asymmetric encryption for robust authentication.
