Abstract

This article presents the study on development of a privacy-protection service platform for industrial IoT systems and general users, leveraging homomorphic encryption to enable secure data processing in the cloud without requiring decryption. From this study, a privacy-protection service platform for industrial IoT was developed. The platform was designed to be user-friendly and accessible via a mobile application, allowing even non-technical users to manage encryption keys securely. The platform was used as case studies at two factories: one for an oil monitoring system in silos, and the other for a machinery inspection system. The results showed that the platform could perform encryption, decryption, and data transmission with high accuracy and efficiency. Field tests demonstrated accuracy levels of up to four decimal places with small encryption keys, and up to six decimal places with medium and large keys. Data transmission latency was measured at 0.5 seconds per data set for small and medium keys, and five seconds for large keys.
