Modernizing the security of operational technology systems that control critical infrastructure has become a pressing challenge. Because edge devices have limited capabilities, mod…
DiProber: Using Dual Probing to Estimate Tor Relay Capacities in Underloaded Networks
Hussein Darir, Nikita Borisov, Geir Dullerud
Tor is the most popular anonymous communication network. It has millions of daily users seeking privacy while browsing the internet. It has thousands of relays to route and anonymi…
Assessing the Privacy Benefits of Domain Name Encryption
Nguyen Phong Hoang, Arian Akhavan Niaki, Nikita Borisov +2
As Internet users have become more savvy about the potential for their Internet communication to be observed, the use of network traffic encryption technologies (e.g., HTTPS/TLS) i…
Detecting AI Trojans Using Meta Neural Analysis
Xiaojun Xu, Qi Wang, Huichen Li +3
In machine learning Trojan attacks, an adversary trains a corrupted model that obtains good performance on normal data but behaves maliciously on data samples with certain trigger…
Differentially Private Data Generative Models
Qingrong Chen, Chong Xiang, Minhui Xue +4
Deep neural networks (DNNs) have recently been widely adopted in various applications, and such success is largely due to a combination of algorithmic breakthroughs, computation re…
Smartphone Fingerprinting Via Motion Sensors: Analyzing Feasibility at Large-Scale and Studying Real Usage Patterns
Anupam Das, Nikita Borisov, Edward Chou +1
Advertisers are increasingly turning to fingerprinting techniques to track users across the web. As web browsing activity shifts to mobile platforms, traditional browser fingerprin…
Exploring Ways To Mitigate Sensor-Based Smartphone Fingerprinting
Anupam Das, Nikita Borisov, Matthew Caesar
Modern smartphones contain motion sensors, such as accelerometers and gyroscopes. These sensors have many useful applications; however, they can also be used to uniquely identify a…
Defending Tor from Network Adversaries: A Case Study of Network Path Prediction
Joshua Juen, Aaron Johnson, Anupam Das +2
The Tor anonymity network has been shown vulnerable to traffic analysis attacks by autonomous systems and Internet exchanges, which can observe different overlay hops belonging to…
Fingerprinting Smart Devices Through Embedded Acoustic Components
Anupam Das, Nikita Borisov, Matthew Caesar
The widespread use of smart devices gives rise to both security and privacy concerns. Fingerprinting smart devices can assist in authenticating physical devices, but it can also je…
SWEET: Serving the Web by Exploiting Email Tunnels
Amir Houmansadr, Wenxuan Zhou, Matthew Caesar +1
Open communication over the Internet poses a serious threat to countries with repressive regimes, leading them to develop and deploy censorship mechanisms within their networks. Un…
Pisces: Anonymous Communication Using Social Networks
Prateek Mittal, Matthew Wright, Nikita Borisov
The architectures of deployed anonymity systems such as Tor suffer from two key problems that limit user's trust in these systems. First, paths for anonymous communication are buil…
PIRATTE: Proxy-based Immediate Revocation of ATTribute-based Encryption
Sonia Jahid, Nikita Borisov
Access control to data in traditional enterprises is typically enforced through reference monitors. However, as more and more enterprise data is outsourced, trusting third party st…
IP over Voice-over-IP for censorship circumvention
Amir Houmansadr, Thomas Riedl, Nikita Borisov +1
Open communication over the Internet poses a serious threat to countries with repressive regimes, leading them to develop and deploy network-based censorship mechanisms within thei…
Octopus: A Secure and Anonymous DHT Lookup
Qiyan Wang, Nikita Borisov
Distributed Hash Table (DHT) lookup is a core technique in structured peer-to-peer (P2P) networks. Its decentralized nature introduces security and privacy vulnerabilities for appl…
Non-blind watermarking of network flows
Amir Houmansadr, Negar Kiyavash, Nikita Borisov
Linking network flows is an important problem in intrusion detection as well as anonymity. Passive traffic analysis can link flows but requires long periods of observation to reduc…
Multi-Flow Attacks Against Network Flow Watermarks: Analysis and Countermeasures
Negar Kiyavash, Amir Houmansadr, Nikita Borisov
In this paper, we analyze several recent schemes for watermarking network flows that are based on splitting the flow into timing intervals. We show that this approach creates time-…
BotMosaic: Collaborative Network Watermark for Botnet Detection
Amir Houmansadr, Nikita Borisov
Recent research has made great strides in the field of detecting botnets. However, botnets of all kinds continue to plague the Internet, as many ISPs and organizations do not deplo…
SybilControl: Practical Sybil Defense with Computational Puzzles
Frank Li, Prateek Mittal, Matthew Caesar +1
Many distributed systems are subject to the Sybil attack, where an adversary subverts system operation by emulating behavior of multiple distinct nodes. Most recent work to address…
DECENT: A Decentralized Architecture for Enforcing Privacy in Online Social Networks
Sonia Jahid, Shirin Nilizadeh, Prateek Mittal +2
A multitude of privacy breaches, both accidental and malicious, have prompted users to distrust centralized providers of online social networks (OSNs) and investigate decentralized…
