摘　　要：由于无线传感器网络节点在能量、计算能力和存储能力等方面的局限性,传统的网络认证密钥协商协议难以直接应用到无线传感器网络中。为此,基于无证书的公钥密码体制,提出一种适用于无线传感器网络的认证和密钥协商协议,克服传统公钥认证的证书管理问题和基于身份认证的密钥托管问题。通过分析证明该协议满足认证协议各方面的安全属性要求,与已有的认证密钥协商协议相比,系统开销更少。It is an important challenge to find out a suitable key establishment protocol for Wireless Sensor Network（WSN） due to limitations of energy,computation capability and storage resources.Many traditional protocols are not suitable.This paper presents a certificateless authentication and key agreement protocol for WSN.The protocol does not need for certificate management,and solves the key escrow problem in the identity-based cryptography.The new protocol achieves kinds of the desired security attributes,and it keeps the nice computational efficiency compared with other protocols.
