6LoWPAN网络中移动集群的边缘认证切换方法

Edge Authentication Handover Method of Mobile Cluster in 6lowpan Network

针对6LoWPAN网络中移动集群在切换过程中存在的切换延迟高、计算开销大的问题,提出一种边缘认证切换方法,以支持资源受限节点的安全切换。提出的方法在初始化阶段执行完全身份验证,在切换之前将切换密钥预分配给集群节点和关联节点。上述方法实现了在关联节点上执行移动集群的认证切换,并且仅使用轻量级加密算法。安全性分析和仿真结果表明,所提方法满足安全要求,并有效减少了通信延迟和计算开销,从而降低了切换延迟,实现了集群的快速安全切换。

In order to solve the problems of high handover latency and high computational overhead in the handoff process of mobile clusters in the 6 LoWPAN network,an edge authentication handover method is proposed to support the secure handoff of resource-constrained nodes.The proposed method performs full authentication in the initialization phase,and the handover key is pre-allocated to cluster nodes and associated nodes before handover.This method realizes the authentication handover of mobile clusters on the associated nodes,and only uses a lightweight encryption algorithm.The security analysis and simulation results show that the method meets the security requirements,reduces the communication delay and computing overhead,thus reducing the handover latency,and realizing the fast and secure handover of clusters.
