Testing the Structure of a Gaussian Graphical Model with Reduced Transmissions in a Distributed Setting
Yicheng Chen, Rick S. Blum, Brian M. Sadler +1
Testing a covariance matrix following a Gaussian graphical model (GGM) is considered in this paper based on observations made at a set of distributed sensors grouped into clusters.…
Quickest Detection of Time-Varying False Data Injection Attacks in Dynamic Linear Regression Models
Jiangfan Zhang, Xiaodong Wang
Motivated by the sequential detection of false data injection attacks (FDIAs) in a dynamic smart grid, we consider a more general problem of sequentially detecting time-varying FDI…
Consensus-based Distributed Quickest Detection of Attacks with Unknown Parameters
Jiangfan Zhang, Xiaodong Wang
Sequential attack detection in a distributed estimation system is considered, where each sensor successively produces one-bit quantized samples of a desired deterministic scalar pa…
Asymptotically Optimal Stochastic Encryption for Quantized Sequential Detection in the Presence of Eavesdroppers
Jiangfan Zhang, Xiaodong Wang
We consider sequential detection based on quantized data in the presence of eavesdropper. Stochastic encryption is employed as a counter measure that flips the quantization bits at…
A Fundamental Limitation on Maximum Parameter Dimension for Accurate Estimation with Quantized Data
Jiangfan Zhang, Rick S. Blum, Lance Kaplan +1
It is revealed that there is a link between the quantization approach employed and the dimension of the vector parameter which can be accurately estimated by a quantized estimation…
