【摘要】:使用无线信道的物理层信息在无线设备间生成私密密钥用于确保移动环境的安全,如今受到了广泛关注。然而在现实环境中,在多个设备之间生成群密钥以确保群安全通信的问题仍然存在挑战。针对无线网络星型拓扑结构,提出一种基于中心节点成对生成策略的群密钥产生方案。相比于文献中提出的利用群内节点间的接收信号强度差分实现提取群密钥的方案,详细分析了它们各自能实现的群密钥容量并给出了数值计算结果。分析表明,提出的基于成对生成策略的群密钥产生方法在密钥率方面优于文献中的差分提取方案。
[Abstract]:The use of physical layer information of wireless channels to generate private keys between wireless devices to ensure the security of mobile environments has received widespread attention. The problem of generating group keys between multiple devices to ensure group secure communication remains a challenge. A group key generation scheme based on the pairwise generation strategy of central nodes is proposed. The group key capacity which they can realize is analyzed in detail and the numerical results are given. The results show that the proposed group key generation method based on pairwise generation strategy is superior to the difference extraction scheme in terms of key rate.
