Enhanced secure zigbee light link protocol based on network key update mechanism

Abstract

In recent years, the market demand for smart devices continues to increase. As a widely used communication technology, applications of ZigBee Light Link protocol and its security have received extensive attention in recent years. This article discusses the security of the ZigBee Light Link commissioning protocol. Based on the hash chain technology, this paper proposes a network key update protocol based on the security-enhanced ZLL protocol. In the end, the performance evaluation and comparison are given.
