Secure Industrial IoT Data Transmission and Cloud Integration: A Unidirectional Security Gateway Approach for AWS IoT and SiteWise

Abstract

The rapid advancement of Industrial Internet of Things (IIoT) has led to the integration of numerous devices and systems in industrial environments, enabling real-time data collection, analysis, and decision-making. However, this integration also introduces significant security challenges, particularly in the transmission of sensitive data to cloud platforms. This paper proposes a unidirectional security gateway (USG) approach to ensure secure data transmission from industrial IoT devices to AWS IoT and SiteWise. The USG acts as a one-way data diode, preventing any unauthorized data flow from the cloud back to the industrial network, thereby enhancing the overall security of the system. The paper discusses the design, implementation, and evaluation of the USG, including its architecture, algorithms, and performance metrics. Additionally, a case study is presented to demonstrate the effectiveness of the proposed approach in a real-world industrial setting
