“…This security feature is used to protect the network against attempts to inject bad traffic into the network and thus consuming network resources, transmitting packets which cannot be decrypted or used in the network. A packet secured at network layer is presented in Figure 3, having the following components: NWK Header, AUX Header, NWK Payload, and MIC [20,21].…”

In recent times, the security of sensor networks, especially in the field of IoT, has become a priority. This article focuses on the security features of the Zigbee protocol in Xbee devices developed by Digi International, specifically in the Xbee 3 (XB3-24) devices. Using the TI LaunchXL-CC26X2R1 kit, we intercepted and analyzed packets in real-time using the Wireshark application. The study encompasses various stages of network formation, packet transmission and analysis of security key usage, considering scenarios as follows: without security, distributed security mode and centralized security mode. Our findings highlight the differences in security features of Xbee devices compared to the Zigbee protocol, validating and invalidating methods of establishing security keys, vulnerabilities, strengths, and recommended security measures. We also discovered that security features of the Xbee 3 devices are built around a global link key preconfigured therefore constituting a vulnerability, making those devices suitable for man-in-the-middle and reply attacks. This work not only elucidates the complexities of Zigbee security in Xbee devices but also provides direction for future research for authentication methods using asymmetric encryption algorithms such as digital signature based on RSA and ECDSA.

“…Numerous papers discuss AES hardware implementations in various technologies that are very com- It is well understood that hardware encryption can reduce the energy consumption. However, in practice a balance needs to be found between the additional hardware cost and the reduction of energy consumption, hence it is not obvious that hardware encryption is always the best solution [14]. In order to find this equilibrium, we have compared the energy consumption of different hardware and software implementations.…”

This paper describes the experiments that have been conducted to determine the optimal implementation method for AES (Advanced Encryption Standard) data encryption in a ZigBee network in terms of energy consumption. Four possible scenarios have been considered. The first one is a freely available AES‐cryptographic algorithm on the processor which controls the ZigBee nodes. The second also involves the processor but is based on a proprietary, highly optimized algorithm. The other methods are based on hardware implementations. Whereas the third option is based on a cryptographic block, embedded in the ZigBee node controller, the last solution utilizes an AES128‐CBC‐MAC hardware co‐processor embedded on a Spartan 3A FPGA. The ZigBee modules in the network contain an 8‐bit microcontroller which takes care of the ZigBee protocol stack—and the encryption calculations in all but the last case. All approaches are examined and compared. We show that the usage of a microcontroller with an on‐board AES processor is the optimal design choice for a new hardware platform. An optimized software library gives the best results when extending an existing platform. This paper gives developers an idea of the amount of energy they can gain/lose by choosing one of the four solutions. Copyright © 2010 John Wiley & Sons, Ltd.
