Encrypted collision avoidance maneuver via variational optimization
Yeongjun Jang, Jihoon Suh, Kenshiro Oguri +1
We propose an encrypted collision avoidance maneuver (CAM) design protocol using homomorphic encryption (HE) that enables operators to outsource CAM design to an untrusted server w…
Mean Field Analysis of Blockchain Systems
Yanni Georghiades, Takashi Tanaka, Sriram Vishwanath
We present a novel framework for analyzing blockchain consensus mechanisms by modeling blockchain growth as a Partially Observable Stochastic Game (POSG) which we reduce to a set o…
Privacy-Preserving Fully Distributed Gaussian Process Regression
Yeongjun Jang, Kaoru Teranishi, Jihoon Suh +1
Although distributed Gaussian process regression (GPR) enables multiple agents to jointly learn a model of the target function, its collaborative nature poses a risk of private dat…
A Learning With Errors based encryption scheme for dynamic controllers that discloses residue signal for anomaly detection
Yeongjun Jang, Joowon Lee, Junsoo Kim +2
Although encrypted control systems ensure confidentiality of private data, it is challenging to detect anomalies without the secret key as all signals remain encrypted. To address…
