Capstone: A Capability-based Foundation for Trustless Secure Memory Access (Extended Version)
Jason Zhijingcheng Yu, Conrad Watt, Aditya Badole +2
Capability-based memory isolation is a promising new architectural primitive. Software can access low-level memory only via capability handles rather than raw pointers, which provi…
Epione: Lightweight Contact Tracing with Strong Privacy
Ni Trieu, Kareem Shehata, Prateek Saxena +2
Contact tracing is an essential tool in containing infectious diseases such as COVID-19. Many countries and research groups have launched or announced mobile apps to facilitate con…
Quantitative Verification of Neural Networks And its Security Applications
Teodora Baluta, Shiqi Shen, Shweta Shinde +2
Neural networks are increasingly employed in safety-critical domains. This has prompted interest in verifying or certifying logically encoded properties of neural networks. Prior w…
Practical Verifiable In-network Filtering for DDoS defense
Deli Gong, Muoi Tran, Shweta Shinde +4
In light of ever-increasing scale and sophistication of modern DDoS attacks, it is time to revisit in-network filtering or the idea of empowering DDoS victims to install in-network…
Exploiting The Laws of Order in Smart Contracts
Aashish Kolluri, Ivica Nikolic, Ilya Sergey +2
We investigate a family of bugs in blockchain-based smart contracts, which we call event-ordering (or EO) bugs. These bugs are intimately related to the dynamic ordering of contrac…
BesFS: A POSIX Filesystem for Enclaves with a Mechanized Safety Proof
Shweta Shinde, Shengyi Wang, Pinghai Yuan +3
New trusted computing primitives such as Intel SGX have shown the feasibility of running user-level applications in enclaves on a commodity trusted processor without trusting a lar…
Finding The Greedy, Prodigal, and Suicidal Contracts at Scale
Ivica Nikolic, Aashish Kolluri, Ilya Sergey +2
Smart contracts---stateful executable objects hosted on blockchains like Ethereum---carry billions of dollars worth of coins and cannot be updated once deployed. We present a new s…
Preventing Your Faults From Telling Your Secrets: Defenses Against Pigeonhole Attacks
Shweta Shinde, Zheng Leong Chua, Viswesh Narayanan +1
New hardware primitives such as Intel SGX secure a user-level process in presence of an untrusted or compromised OS. Such "enclaved execution" systems are vulnerable to several sid…
