摘要
在无线传感器网络(Wireless Sensor Network,WSN)中,如何消耗较小的计算量建立传感器之间的身份认证和会话密钥一直是学界研究的热点。基于椭圆曲线密码体制设计了一种新的认证密钥协商协议。之后对新协议进行了安全性分析和性能分析。分析结果表明,新方案在确保自身安全的前提下,以较小的计算代价实现了WSN网络节点之间的安全密钥协商目标。
In Wireless Sensor Network, how to realize the authentication and session establishment among the sensors with lower computational cost is always an interesting issue. This paper proposes a novel two-party authenticated key agreement protocol based on the elliptic curve cryptography, and discusses the security and performance of this protocol. The results show that this protocol can help users establish the secure session key with lower computational cost.
