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。

Abstract: 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.

Key words: Wireless Sensor Network(WSN), certificateless, public key, key agreement, authentication protocol
