Wireless sensor networks (WSNs) play an important role in the industrial Internet of Things (IIoT) and have been widely used in many industrial fields to gather data of monitoring area. However, due to the open nature of wireless channel and resource-constrained feature of sensor nodes, how to guarantee that the sensitive sensor data can only be accessed by a valid user becomes a key challenge in IIoT environment. Some user authentication protocols for WSNs have been proposed to address this issue. However, previous works more or less have their own weaknesses, such as not providing user anonymity and other ideal functions or being vulnerable to some attacks. To provide secure communication for IIoT, a user authentication protocol scheme with privacy protection for IIoT has been proposed. The security of the proposed scheme is proved under a random oracle model, and other security discussions show that the proposed protocol is robust to various attacks. Furthermore, the comparison results with other related protocols and the simulation by NS-3 show that the proposed protocol is secure and efficient for IIoT.

基于鲁棒ECC的可证明安全认证协议，具有工业物联网的隐私保护

无线传感器网络（WSN）在工业物联网（IIoT）中发挥着重要作用，并已广泛用于许多工业领域以收集监视区域的数据。然而，由于无线信道的开放性和传感器节点的资源受限特性，如何确保敏感传感器数据只能由有效用户访问成为IIoT环境中的关键挑战。已经提出了一些用于WSN的用户身份验证协议来解决此问题。但是，先前的作品或多或少都有其自身的弱点，例如不提供用户匿名性和其他理想功能，或者容易受到某些攻击。为了提供用于IIoT的安全通信，已经提出了具有针对IIoT的隐私保护的用户认证协议方案。该方案的安全性是在随机预言模型下证明的，其他安全性讨论表明，该方案对各种攻击具有鲁棒性。此外，与其他相关协议的比较结果以及NS-3的仿真结果表明，该协议对于IIoT是安全有效的。
