WSNs中轻量级密钥管理方案设计

A LightWeight Key Management Scheme for WSNs

无线传感器网络节点资源有限的特点和通信方式决定了这种网络容易受到攻击.节点之间通过加密通信数据和认证的方式来保证通信的保密性、完整性和可用性,密钥管理是实现网络安全的关键基础.分析了无线传感器网络中的密钥管理方案,提出了一种基于EBS的密钥管理方案,能够安全高效的对传感器网络中的密钥进行更新.分析表明,该方案具有安全性高、计算量小的特点,也节省了网络的计算和存储资源.

WSNs(Wireless Sensor Networks) are vulnerable to security attacks due to the communication nature and limited computation capabilities of the sensor nodes.The key management scheme is crucial to enable encryption and authentication among sensor nodes to protect confidentiality,integrity and availability of the communications of WSNs.Based on studying key management schemes of WSNs,a key management scheme is proposed based on EBS,it can refresh the keys in WSNs securely and efficiently.The final analysis shows that this scheme enhances network security while conservatively consuming nodes' compute resources,meanwhile,it saves the resources of WSNs.
