Robust security is highly coveted in real wireless sensor network (WSN) applications since wireless sensors' sense critical data from the application environment. This article presents an efficient and adaptive mutual authentication framework that suits real heterogeneous WSN-based applications (such as smart homes, industrial environments, smart grids, and healthcare monitoring). The proposed framework offers: (i) key initialization; (ii) secure network (cluster) formation (i.e., mutual authentication and dynamic key establishment); (iii) key revocation; and (iv) new node addition into the network. The correctness of the proposed scheme is formally verified. An extensive analysis shows the proposed scheme coupled with message confidentiality, mutual authentication and dynamic session key establishment, node privacy, and message freshness. Moreover, the preliminary study also reveals the proposed framework is secure against popular types of attacks, such as impersonation attacks, man-in-the-middle attacks, replay attacks, and information-leakage attacks. As a result, we believe the proposed framework achieves efficiency at reasonable computation and communication costs and it can be a safeguard to real heterogeneous WSN applications.
在真正的无线传感器网络（WSN）应用中，稳健的安全性是非常令人向往的，因为无线传感器从应用环境中感知关键数据。本文提出了一种适用于真正异构 WSN 应用（如智能家居、工业环境、智能电网和医疗监测）的高效自适应相互认证框架。所提出的框架提供：（i）密钥初始化；（ii）安全网络（簇）形成（即相互认证和动态密钥建立）；（iii）密钥吊销；和（iv）新节点添加到网络中。所提出的方案的正确性被形式验证。广泛的分析表明，所提出的方案结合了消息保密性、相互认证和动态会话密钥建立、节点隐私和消息新鲜度。此外，初步研究还表明，所提出的框架可以抵御各种常见类型的攻击，如仿冒攻击、中间人攻击、重放攻击和信息泄露攻击。因此，我们相信所提出的框架在合理的计算和通信成本下实现了效率，并且可以成为真正异构 WSN 应用的保障。
