摘　　要：分析了无线传感器网络中已有多播认证协议的不足,给出了基于PKC的WSN安全协议研究进展,并提出一种基于身份的高效多播认证协议。该协议具有消息恢复功能,可有效缩短签名长度,减少协议的通信和计算开销,克服公钥密码体制开销大的缺点。在随机预言模型下证明了协议在适应性选择消息攻击和身份攻击下是存在性不可伪造的。最后,基于MICA2DOT无线传感器网络节点对协议的能量消耗进行了定量分析,结果表明,本协议的性能优于HESS、Zhang和BLS等协议,能更好地适用于资源受限的WSN环境。In order to overcome the drawback of the existent multicast authentication protocol in WSN, the PKC-based services for WSN was explored and an efficient ID-based multicast authentication protocol was presented. The protocol with message recovery provided the feature that the message was recoverable from the signature and hence the computational cost and communication overhead of the protocol had been reduced greatly. This protocol was proved secure against existential forgery under adaptive chosen message and ID attack in the random oracle model. The performance analysis results show that the proposed scheme can effectively reduce resource cost, adapt the characteristics of WSN and is clearly superior to the HESS, Zhang and BLS protocols.
