Taking Advantage of Rational Canonical Form for Faster Ring-LWE based Encrypted Controller with Recursive Multiplication
Donghyeon Song, Yeongjun Jang, Joowon Lee +1
This paper aims to provide an efficient implementation of encrypted linear dynamic controllers that perform recursive multiplications on a Ring-Learning With Errors (Ring-LWE) base…
Sensor Attack Detection Method for Encrypted State Observers
Yeongjun Jang, Sangwon Lee, Junsoo Kim
This paper proposes an encrypted state observer that is capable of detecting sensor attacks without decryption. We first design a state observer that operates over a finite field o…
A polynomial-based QCQP solver for encrypted optimization
Sebastian Schlor, Andrea Iannelli, Junsoo Kim +2
In this paper, we present a novel method for solving a class of quadratically constrained quadratic optimization problems using only additions and multiplications. This approach en…
Stabilization by Controllers Having Integer Coefficients
Joowon Lee, Donggil Lee, Junsoo Kim
The system property of ``having integer coefficients,'' that is, a transfer function has an integer monic polynomial as its denominator, is significant in the field of encrypted co…
Documentation on Encrypted Dynamic Control Simulation Code using Ring-LWE based Cryptosystems
Yeongjun Jang, Joowon Lee, Junsoo Kim
Encrypted controllers offer secure computation by employing modern cryptosystems to execute control operations directly over encrypted data without decryption. However, incorporati…
Anomaly Detection with LWE Encrypted Control
Rijad Alisic, Junsoo Kim, Henrik Sandberg
Detecting attacks using encrypted signals is challenging since encryption hides its information content. We present a novel mechanism for anomaly detection over Learning with Error…
