Fine-grained Poisoning Attack to Local Differential Privacy Protocols for Mean and Variance Estimation
Xiaoguang Li, Ninghui Li, Wenhai Sun +2
Although local differential privacy (LDP) protects individual users' data from inference by an untrusted data curator, recent studies show that an attacker can launch a data poison…
Speedster: A TEE-assisted State Channel System
Jinghui Liao, Fengwei Zhang, Wenhai Sun +1
State channel network is the most popular layer-2 solution to theissues of scalability, high transaction fees, and low transaction throughput of public Blockchain networks. However…
Monitoring-based Differential Privacy Mechanism Against Query-Flooding Parameter Duplication Attack
Haonan Yan, Xiaoguang Li, Hui Li +3
Public intelligent services enabled by machine learning algorithms are vulnerable to model extraction attacks that can steal confidential information of the learning models through…
Towards Overcoming the Undercutting Problem
Tiantian Gong, Mohsen Minaei, Wenhai Sun +1
Mining processes of Bitcoin and similar cryptocurrencies are currently incentivized with voluntary transaction fees and fixed block rewards which will halve gradually to zero. In t…
Fingerprinting Encrypted Voice Traffic on Smart Speakers with Deep Learning
Chenggang Wang, Sean Kennedy, Haipeng Li +5
This paper investigates the privacy leakage of smart speakers under an encrypted traffic analysis attack, referred to as voice command fingerprinting. In this attack, an adversary…
