Design of Controllers Having Integer Coefficients for Encrypted Control

Rising Star Symposium on Cyber-Physical Systems Security, Resilience, and Privacy https://shorturl.at/C3RZy Joowon Lee from Seoul National University Encrypted control offers a promising solution for enhancing security in networked control systems, enabling direct control operations over encrypted data. However, its implementation is often challenged by the constraints of homomorphic encryption, particularly the requirement that linear dynamic controllers should ``have integer coefficients.’’ This talk explores the rationale behind this requirement and addresses the problem of designing such controllers.
