摘　　要：无线传感器网络(Wireless Sensor Networks,WSN)是物联网的重要组成部分,因为WSN能通过因特网将采集到的数据发送到云服务器.认证和密钥协商机制是一个重要的密码学概念,可以确保数据传输的安全和完整性.传感器节点是资源受限的设备,因此目前多数认证和密钥协商机制在计算效率上并不适用于WSN.针对该问题,本文提出了一种新的认证和密钥协商机制,该方案是一种基于椭圆曲线的轻量级认证和密钥协商方案.在eCK安全模型下,将方案的安全性规约到CDH数学困难假设之上,形式化的证明了方案的安全性.最后通过方案对比,表明文章所提出的方案实现了计算效率和安全属性之间的平衡.Wireless Sensor Networks is one of the most important components in the Internet if Things,since they enable gathering and transmitting of data to the cloud server via the Internet.Authenticated and key agreement mechanism is a very important concept of cryptography,which can be used to ensure the confidentiality and integrity of data.Since sensor node is resource-constrained device,most of authenticated and key agreement mechanism are not applicable to WSN in terms of computational efficiency.To solve this problem,a new authenticated and key agreement mechanism is proposed.This scheme is a lightweight authenticated and key agreement scheme.The scheme′s security is reduced to CDH mathematical hardness assumption,and is formally proved in the eCK model.By comparison,the proposed scheme shows the balance between computational efficiency and security properties.
