摘　　要：受WackerA等人提出的基于P2P的大规模多用户虚拟环境中认证思想的启发,提出一种适用于无线传感器网络的高效鲁棒的对等认证方案。基于分布式信任模型,该方案通过分布式多节点表决方式保证公钥与私钥之间的对应关系,取代证书方式,避免了证书的颁发/更新、存储、索取等计算和通信开销,在提高公钥加密体制应用效率的同时还增强了系统的鲁棒性。形式化证明该方案是安全的。基于MICA2DOT无线传感器网络节点对方案的能量消耗进行了定量分析,结果表明该方案能很好地适用于资源受限的WSN环境。Drawing inspiration from Wacker A et al,towards an authentication service for Peer-to-Peer based massively multi-user virtual environments,an Efficient and Robust Peer-to-Peer Authentication（ER2PA）scheme for Wireless Sensor Networks is proposed.Based on distributed trust model,the scheme assures the binding of public key and private key through voting instead of certificate.It improves the scheme with efficiency and robustness by eliminating computing and communication overhead produced with issuing,renewal,storage and retrieving operations regarding certificates.It is proved that the scheme is secure formally.Based on MICA2DOT WSN,the performance of the proposed scheme is analyzed and the results show this scheme is more suitable for WSN with resource-constrained features.
