Experimental Examination of Secure Two-Party Controller Computation
The paper experimentally validates a novel secure two-party computation protocol for running dynamic controllers over secret sharing, demonstrating its feasibility for real-time control systems despite online communication overhead.
Abstract
More Like ThisA secure two-party computation protocol for running dynamic controllers over secret sharing has recently been proposed. Unlike encrypted control schemes based on homomorphic encryption, this protocol enables operating dynamic controllers for an infinite time horizon without controller-state decryption, controller-state reset, or input re-encryption. However, the two-party setting introduces additional online communication between the computing parties, which may hinder real-time feasibility. In this study, we demonstrate the feasibility of the protocol through implementation on a commercial cloud platform with an inverted pendulum testbed. Experimental results show that the proposed protocol successfully stabilized the pendulum despite the online communication overhead.
