Caching-based Multicast Message Authentication in Time-critical Industrial Control Systems
Utku Tefek, Ertem Esiner, Daisuke Mashima +2
Attacks against industrial control systems (ICSs) often exploit the insufficiency of authentication mechanisms. Verifying whether the received messages are intact and issued by leg…
Secure and Ultra-Reliable Provenance Recovery in Sparse Networks: Strategies and Performance Bounds
Suraj Sajeev, Manish Bansal, Sriraam S +3
Provenance embedding algorithms are well known for tracking the footprints of information flow in wireless networks. Recently, low-latency provenance embedding algorithms have rece…
HASA-net: A non-intrusive hearing-aid speech assessment network
Hsin-Tien Chiang, Yi-Chiao Wu, Cheng Yu +4
Without the need of a clean reference, non-intrusive speech assessment methods have caught great attention for objective evaluations. Recently, deep neural network (DNN) models hav…
BlindSignedID: Mitigating Denial-of-Service Attacks on Digital Contact Tracing
Bo-Rong Chen, Yih-Chun Hu
Due to the recent outbreak of COVID-19, many governments suspended outdoor activities and imposed social distancing policies to prevent the transmission of SARS-CoV-2. These measur…
HyperService: Interoperability and Programmability Across Heterogeneous Blockchains
Zhuotao Liu, Yangxi Xiang, Jian Shi +5
Blockchain interoperability, which allows state transitions across different blockchain networks, is critical functionality to facilitate major blockchain adoption. Existing intero…
Convolution Attack on Frequency-Hopping by Full-Duplex Radios
J. Harshan, Yih-Chun Hu
We propose a new adversarial attack on frequency-hopping based wireless communication between two users, namely Alice and Bob. In this attack, the adversary, referred to as Eve, in…
Signal Jamming Attacks Against Communication-Based Train Control: Attack Impact and Countermeasure
Subhash Lakshminarayana, Jabir Shabbir Karachiwala, Sang-Yoon Chang +4
We study the impact of signal jamming attacks against the communication based train control (CBTC) systems and develop the countermeasures to limit the attacks' impact. CBTC suppor…
CLEF: Limiting the Damage Caused by Large Flows in the Internet Core (Technical Report)
Hao Wu, Hsu-Chun Hsiao, Daniele E. Asoni +3
The detection of network flows that send excessive amounts of traffic is of increasing importance to enforce QoS and to counter DDoS attacks. Large-flow detection has been previous…
Cognitive Radio from Hell: Flipping Attack on Direct-Sequence Spread Spectrum
J. Harshan, Yih-Chun Hu
In this paper, we introduce a strong adversarial attack, referred to as the flipping attack, on Direct-Sequence Spread Spectrum (DSSS) systems. In this attack, the attacker, which…
Enabling Work-conserving Bandwidth Guarantees for Multi-tenant Datacenters via Dynamic Tenant-Queue Binding
Zhuotao Liu, Kai Chen, Haitao Wu +4
Today's cloud networks are shared among many tenants. Bandwidth guarantees and work conservation are two key properties to ensure predictable performance for tenant applications an…
Fine-Grained Endpoint-Driven In-Network Traffic Control for Proactive DDoS Attack Mitigation
Zhuotao Liu, Hao Jin, Yih-Chun Hu +1
Volumetric attacks, which overwhelm the bandwidth of a destination, are among the most common DDoS attacks today. Despite considerable effort made by both research and industry, ou…
TorPolice: Towards Enforcing Service-Defined Access Policies in Anonymous Systems
Zhuotao Liu, Yushan Liu, Philipp Winter +2
Tor is the most widely used anonymity network, currently serving millions of users each day. However, there is no access control in place for all these users, leaving the network v…
Deadline-Aware Multipath Communication: An Optimization Problem
Laurent Chuat, Adrian Perrig, Yih-Chun Hu
Multipath communication not only allows improved throughput but can also be used to leverage different path characteristics to best fulfill each application's objective. In particu…
Insider-Attacks on Physical-Layer Group Secret-Key Generation in Wireless Networks
J. Harshan, Sang-Yoon Chang, Yih-Chun Hu
Physical-layer group secret-key (GSK) generation is an effective way of generating secret keys in wireless networks, wherein the nodes exploit inherent randomness in the wireless c…
A System-Theoretic Clean Slate Approach to Provably Secure Ad Hoc Wireless Networking
