© 2019 IEEE. Secure communication is a necessity that must be considered in any smart application to guarantee the confidentiality of information. Recently, ZigBee has been utilized in different smart applications such as automatic metering, power fraud detection, industrial automation and many more. In this research paper, we evaluate the performance of ZigBee from a security perspective. We explore the ZigBee built-in security services, encryption techniques, security keys, and the trust center. The research findings serve as guidelines to focus on wireless communication security in general and on the ZigBee security issues in specific. There is a crucial need to fill in the gap where ZigBee has low-complexity processing capabilities and the need to integrate more robust enhancements and security controls.
