Analysis of Dynamic-Key LWE-Based Encrypted Control Systems for Asymptotic Stability and Numerical Safety
Jungjin Park, Kiminao Kogiso
This study analyzes dynamic-key Learning-with-Errors (LWE)-based encrypted state-feedback control systems with time-varying encoders and decoders. Using a Lyapunov-based approach,…
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…
