一种改进的无线传感器网络的匿名认证与密钥协商方案

An Improved Anonymous Authentication and Key Agreement Scheme for Wireless Sensor Networks

作为物联网的重要组成部分,无线传感器网络(WSNs)通信技术广泛应用于军事监控、环境监测、医疗卫生和城市交通等各种领域.然而,WSNs容易遭受无线链路的各种攻击,如窃听和篡改.如何确保敏感或重要的信息仅为合法用户提供成为一个具有挑战性的问题.针对Chang等提出一种双向认证和密钥交换方案不能支持用户匿名,提出了一种改进的无线传感器网络的匿名认证与密钥协商方案.新方案在满足用户匿名的同时,抵抗Chang方案的安全缺陷,并满足前向安全的会话密钥.与已有的同类方案相比,该方案具有更高的安全性.

As an important part of the Internet of Things,wireless sensor networks(WSNs)communication technology is widely used in various fields,such as military surveillance,environmental monitoring,medical care,and urban transportation,etc.However,WSNs is vulnerable to various attacks on wireless links,such as eavesdropping and tampering.How to ensure that sensitive or important information is only available to legitimate users becomes a challenging issue.Chang proposed a two-factor authentication and key agreement scheme,but it cannot support the users anonymity.An improved anonymous authentication and key agreement scheme for wireless sensor networks is proposed.The new scheme supports user anonymity,it can resist the defects of Chang’s scheme,meet the perfect forward secrecy,which has higher security than the existing similar schemes.
