Protecting DeFi Platforms against Non-Price Flash Loan Attacks
Abdulrahman Alhaidari, Balaji Palanisamy, Prashant Krishnamurthy
Smart contracts in Decentralized Finance (DeFi) platforms are attractive targets for attacks as their vulnerabilities can lead to massive amounts of financial losses. Flash loan at…
Cognitive Radio Networks: Realistic or Not?
Konstantinos Pelechrinis, Prashant Krishnamurthy, Martin Weiss +1
A large volume of research has been conducted in the cognitive radio (CR) area the last decade. However, the deployment of a commercial CR network is yet to emerge. A large portion…
Sequential vs. Simultaneous Entanglement Swapping under Optimal Link-Layer Control
Priyam Srivastava, Akshat R. Sabavat, Siddharth Jain +6
Connection-less, packet-switched quantum network architectures distribute entanglement across multi-hop paths through sequential entanglement swapping, in which each node acts on p…
HI-QDC: An Isometric Modular Scalable Architecture for Quantum Data Centers
Mohadeseh Azari, Anoosha Fayyaz, Amy Babay +3
Server-centric quantum data-center architectures offer scalability by distributing communication tasks across QPUs rather than concentrating complexity in a centralized switching c…
Fidelity-Guaranteed Entanglement Routing with Distributed Purification Planning
Anthony Gatti, Anoosha Fayyaz, Prashant Krishnamurthy +2
Many quantum-network applications require end-to-end Bell pairs whose fidelity exceeds a request-specific threshold, but existing entanglement routing algorithms either optimize on…
TBAM: Towards An Agent-Based Model to Enrich Twitter Data
Usman Anjum, Vladimir Zadorozhny, Prashant Krishnamurthy
Twitter (one example of microblogging) is widely being used by researchers to understand human behavior, specifically how people behave when a significant event occurs and how it c…
Comparing GHZ-Based Strategies for Multipartite Entanglement Distribution in 2D Repeater Networks
Mohadeseh Azari, Amy Babay, Prashant Krishnamurthy +1
We conduct a comparative study to determine the initial quality necessary to extend the distance range of an -qubit GHZ state (the parent state) using two-dimensional repeaters.…
On Selecting Paths for End-to-End Entanglement Creation in Quantum Networks
Anoosha Fayyaz, Prashant Krishnamurthy, Kaushik P. Seshadreesan +2
Optimal routing is a fundamental challenge in quantum networking, with several approaches proposed to identify the most efficient path for end-to-end (e2e) entanglement generation…
On-Chain Decentralized Learning and Cost-Effective Inference for DeFi Attack Mitigation
Abdulrahman Alhaidari, Balaji Palanisamy, Prashant Krishnamurthy
Billions of dollars are lost every year in DeFi platforms by transactions exploiting business logic or accounting vulnerabilities. Existing defenses focus on static code analysis,…
Spotting Anomalous Trades in NFT Markets: The Case of NBA Topshot
Konstantinos Pelechrinis, Xin Liu, Prashant Krishnamurthy +1
Non-Fungible Token (NFT) markets are one of the fastest growing digital markets today, with the sales during the third quarter of 2021 exceeding $10 billions! Nevertheless, these e…
Toward Hop-Independent Fidelity in Quantum Data Centers: Resource Requirements for Entanglement Purification
Mohadeseh Azari, Anoosha Fayyaz, Amy Babay +3
Quantum data-center networks must distribute entanglement between QPUs over paths whose length grows with system scale, but each entanglement-swapping step reduces the quality of t…
To Purify or Not to Purify: Entanglement Purification under Input Fidelity Asymmetry in Quantum Networks
Anoosha Fayyaz, Prashant Krishnamurthy, Kaushik Seshadreesan +2
Entanglement purification with two entangled resource pairs is widely employed in the literature on quantum repeater networks to counteract fidelity degradation introduced by noisy…
Gaming the Game: Honeypot Venues Against Cheaters in Location-based Social Networks
Konstantinos Pelechrinis, Prashant Krishnamurthy, Ke Zhang
The proliferation of location-based social networks (LBSNs) has provided the community with an abundant source of information that can be exploited and used in many different ways.…
