ZigBee网络物理层安全传输方法设计

Design for Security Communications in Physical Layer of ZigBee Network

作为一种低功耗短距离和低速率接入网方式,ZigBee技术在智能家居、精细农业和智慧城市等领域具有广泛工程应用价值,其数据安全问题受到广泛关注。ZigBee网络现有安全策略多采用密钥加密机制,在物理层实现无密钥安全传输则少有研究。基于星型拓扑结构在物理层设计了安全传输策略,既能满足对智能终端设备低实现复杂度和低能耗要求,又能有效抵御非安全模式下的窃听攻击。

As a kind of low-power,short-distance and low-rate access network,ZigBee technology has wide appliction in home automation,precision agriculture,smart city and other areas. Its security problem has been attracted widespread attention. There are few researches on the security of ZigBee network,which is based on the key encryption mechanism. Based on the star topology structure,a secure transmission strategy is designed,which can not only meet the requirements of low complexity and low energy consumption,but also can effectively resist the eavesdropping attack in the non secure mode.
