摘　　要：无线传感器网络的应用日益广泛但安全性问题越发突出,由于其计算能力、存储能力和通信能力有限,一直被认为不适合使用公钥密码学方案。然而近年来不需要认证中心的IBE算法的研究成果表明,IBE方案非常适合无线传感器网络。本文提出一种高效的IBE方案,并做了算法介绍,同时在无线传感器网络中提出相应的密钥分配、认证、管理以及更新的应用方案。与现有其他算法相比,新方案具有系统参数短、安全性高等特点。Applications of wireless sensor network is becoming more and more widely, but the security issues prominent seriously. Due to its limited computing power, storage capacity and communication capabilities, which has been considered not suitable for the use of public key cryptography program. However, the research findings of recent years shows that the IBE scheme do not require Certificate Authority and very suitable for wireless sensor networks. This paper presents an effi- cient IBE scheme and introduced the algorithm, also presents the application program of key distribution, anthentication, key management and update in wireless sensor networks. Compared with other existing algorithms, the new scheme has the characteristics of the short system parameters, efficiency and safety.
