The Internet of Things (IoT) stands as one of the emerging technologies because of its novel innovations and solutions for countless domains. As one of the enabling components for IoT, Wireless Sensor Network (WSN) is utilized for various real-world appliances to collect valuable raw sensed data. Here, valuable data from the sensor nodes are suitable to access with the help of a gateway node through the registered user. However, due to the resource constraints of sensor nodes and the exposed nature of the wireless frequency, security has turned out to a considerable task in WSN. Authentication is a primary security facility that can ensure the legitimacy of data access in WSN. There are numerous 2-factor verification protocols in related work based on a smartcard, public-key, and password. However, most of them have trouble reconciling proficiency and security necessities; hence, it is still challenging to implement a 2-factor authentication scheme to satisfy security topographies while preserving suitable proficiency. We designed an enhanced 2-factor verification scheme based on ECC and biometric information in this work. Our proposed scheme accomplishes distinct security features and protocol-designed logic verified with the AVISPA tool. Simulation results demonstrate that the projected scheme is robust, energy-efficient, and well-suited to WSN environments.

物联网 (IoT) 因其针对无数领域的新颖创新和解决方案而成为新兴技术之一。作为物联网的支持组件之一，无线传感器网络 (WSN) 被用于各种现实世界的设备，以收集有价值的原始传感数据。在这里，来自传感器节点的有价值数据适合在网关节点的帮助下通过注册用户访问。然而，由于传感器节点的资源限制和无线频率的暴露特性，安全性已成为 WSN 中的一项重要任务。身份验证是保证无线传感器网络中数据访问合法性的主要安全设施。相关工作中有许多基于智能卡、公钥和密码的双因素验证协议。然而，他们中的大多数人都难以协调熟练程度和安全需求；因此，实施 2 因素身份验证方案以满足安全拓扑，同时保持适当的熟练程度仍然具有挑战性。在这项工作中，我们设计了一种基于 ECC 和生物识别信息的增强型双因素验证方案。我们提出的方案实现了独特的安全功能和协议设计逻辑，并使用 AVISPA 工具进行了验证。仿真结果表明，该计划方案稳健、节能且非常适合 WSN 环境。我们提出的方案实现了独特的安全功能和协议设计逻辑，并使用 AVISPA 工具进行了验证。仿真结果表明，该计划方案稳健、节能且非常适合 WSN 环境。我们提出的方案实现了独特的安全功能和协议设计逻辑，并使用 AVISPA 工具进行了验证。仿真结果表明，该计划方案稳健、节能且非常适合 WSN 环境。
