Date: Friday, July 11, 2025

Time: 1:30 p.m. – 5:00 p.m.

Venue: Room 309, East Bldg. 9, The University of Electro-Communications (UEC)

We are pleased to announce the following research seminar featuring invited and student presentations on cutting-edge topics in cyber-resilient and encrypted control:

・Prof. Jun Ueda (Georgia Institute of Technology / UEC) "Cyber-Resilient Motion Control: Moving Beyond Classical Robustness"

　TBA

・Katsumasa Koshya, Ph.D. student (Kawashima–Miyazaki Lab, University of Tokyo, ) "Encrypted Bilateral Control for Secure Teleoperation"

This talk introduces an approach to enhance cyber-resilience in bilateral control systems used for remote robot manipulation by incorporating encrypted control techniques. The first part discusses a method for detecting and neutralizing false data injection (FDI) attacks exploiting vulnerabilities in homomorphic encryption. The second part reports experimental results using encrypted control based on the HE1N scheme proposed by Dyer.

・Naoki Aizawa, M2 (Kogiso Lab, UEC) "Dynamic Extension of Keyed Homomorphic Encryption and Its Application to Encrypted Control"

　This talk introduces a dynamicalized keyed-homomorphic encryption scheme aimed at enhancing cybersecurity, along with its application to encrypted control systems. In the first part, we explain a keyed-homomorphic encryption method enhanced with algorithms for dynamically updating encryption keys and ciphertexts, and demonstrate how it is used to construct an encrypted control system. In the second part, we present experimental results verifying the effectiveness of the proposed approach through cyberattack detection tests conducted on actual hardware.

No registration or fee is required to attend. All interested participants are welcome to join us at the venue.

If you would like to join the informal gathering after the seminar, please contact Prof. Kogiso (kogiso@uec.ac.jp).
