Abstract: The present key management scheme is analysed based on the Elliptic Curve Cryptosystem(ECC) in Wireless Sensor Network(WSN).Focusing on the lack of forward security,forward secure is added to the key management scheme according to a simple and classic scheme.It implements the application of forward secure in the key management scheme based on the ECC.Furthermore,this paper simulates the scheme with the MICAz nodes,analyzes the security,ROM/RAM and time consumption,and proves the effectiveness of this scheme.

Key words: wireless sensor networks, key management, elliptic curve, forward secure

摘要: 对现有的基于椭圆曲线的无线传感器网络密钥管理方案进行了分析研究,针对现有密钥管理算法不具备前向安全性的问题,以相对简单及较为经典的两个方案为基础,将前向安全的概念引入到密钥管理方案之中,实现了前向安全在椭圆曲线无线传感器网络密钥管理方案中的应用。在此基础上,应用硬件节点MICAz进行硬件模拟,分析了方案的安全性、存储消耗、运行时间,验证了方案的适用性。
