无线传感网络中基于身份的密钥管理方案研究

Research on identity based key management scheme for WSNs

文章结合门限共享方案,提出了一种基于身份的无线传感器网络密钥管理方法,该方法无需认证中心,直接通过各网络节点自身的决策,实现了通讯节点间的双向认证。引入门限密钥机制,能够较好地提高系统的健壮性,在保证系统安全性的同时,有效地改进了系统效率,并且较好地解决了丢包问题,降低了通信开销,能够较好地抵抗入侵,适用于无线传感网中的密钥管理。

In view of the threshold sharing scheme, this paper proposes an ID-based key management scheme for wireless sensor networks（WSNs）. The mutual authentication between the communication nodes can be achieved directly through each network node＇s own decision-making rather than through a certification center. The introduction of threshold key mechanism can improve the robustness and efficiency of the system while ensuring its security. It can also solve the packet loss problem, reduce the communication cost and defend against the intrusion. Theoretical analysis shows that this scheme is suitable for key management in WSNs.
