Dynamic-Key Post-Quantum Encrypted Control Against System Identification Attacks
Jungjin Park, Kiminao Kogiso
This study proposes post-quantum encrypted control systems based on dynamic-key Learning with Errors (LWE) encryption schemes. The proposed method develops update maps that simulta…
Quantization and Security Parameter Design for Overflow-Free Confidential FRIT
Jungjin Park, Osamu Kaneko, Kiminao Kogiso
This study proposes a systematic design procedure for determining the quantization gain and the security parameter in the Confidential Fictitious Reference Iterative Tuning (CFRIT)…
Confidential FRIT via Homomorphic Encryption
Haruki Hoshino, Jungjin Park, Osamu Kaneko +1
Edge computing alleviates the computation burden of data-driven control in cyber-physical systems (CPSs) by offloading complex processing to edge servers. However, the increasing s…
Malleability-Resistant Encrypted Control System with Disturbance Compensation and Real-Time Attack Detection
Naoki Aizawa, Keita Emura, Kiminao Kogiso
This study proposes an encrypted PID control system with a disturbance observer (DOB) using a keyed-homomorphic encryption (KHE) scheme, aiming to achieve control performance while…
Faithful and Privacy-Preserving Implementation of Average Consensus
Kaoru Teranishi, Kiminao Kogiso, Takashi Tanaka
We propose a protocol based on mechanism design theory and encrypted control to solve average consensus problems among rational and strategic agents while preserving their privacy.…
