The Internet of things (IoT) is quickly becoming a reality and wireless sensor networks are going to be certainly widely deployed in the near future. Moreover, wireless sensor networks play an important role in IoT and are considered as an emerging technology with a wide range of applications in many areas. Their importance increases especially with the fast progress of their implementation. Therefore securing these networks becomes a pressing need. ZigBee has established itself as one of the leading communication protocol for WSNs implementation, and the latest version offers improvement over many aspects like low power consumption, flexibility and inexpensive deployment. However problems persist as the enhanced protocol still has many security weaknesses. In this presentation, we highlight relevant security concerns related to the latest ZigBee security features, then we propose countermeasure mechanisms to address some of these weaknesses. We also propose a new approach suitable for ZigBee enabled wireless sensor networks. The proposed solution improves security and decreases considerably the likelihood of successful attacks. Lastly we discuss the security and performance related to the proposed scheme.
