Distributed Detection over Blockchain-aided Internet of Things in the Presence of Attacks
Yiming Jiang, Jiangfan Zhang
Distributed detection over a blockchain-aided Internet of Things (BIoT) network in the presence of attacks is considered, where the integrated blockchain is employed to secure data…
Vulnerability of Finitely-long Blockchains in Securing Data
Yiming Jiang, Jiangfan Zhang
Recently, blockchain has been applied in various fields to secure data exchanges and storage in decentralized systems. In a blockchain application where the task of the application…
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…
Attack Detection in Sensor Network Target Localization Systems with Quantized Data
Jiangfan Zhang, Xiaodong Wang, Rick S. Blum +1
We consider a sensor network focused on target localization, where sensors measure the signal strength emitted from the target. Each measurement is quantized to one bit and sent to…
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…
Functional Forms of Optimum Spoofing Attacks for Vector Parameter Estimation in Quantized Sensor Networks
Jiangfan Zhang, Rick S. Blum, Lance Kaplan +1
Estimation of an unknown deterministic vector from quantized sensor data is considered in the presence of spoofing attacks which alter the data presented to several sensors. Contra…
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…
