Usenix security symposium 2021. Aug 11, 2021 · Join us in Vancouver, B.

Usenix security symposium 2021 Our prototype, PACStack, uses the ARMv8. To proactively address the problem, we propose a systematic evaluation of Android SmartTVs security. Depending on the application, our attacks cause system crashes, data corruption and leakage, degradation of security, and can introduce remote code execution and arbitrary errors. USENIX Security brings together researchers, practitioners, system administrators, system programmers, and others to share and explore the latest advances in the security and privacy of computer systems and networks. Via a rigorous security analysis, we show that PACStack achieves security comparable to hardware-assisted shadow stacks without requiring dedicated hardware. e. , funds are locked for a time proportional to the payment path length) and dependency on specific scripting language functionality (e. We demonstrate our attack on GPT-2, a language model trained on scrapes of the public Internet, and Concept drift poses a critical challenge to deploy machine learning models to solve practical security problems. Hence, the security of RDMA architectures is crucial, yet potential security implications of using RDMA communication remain largely unstudied. We show protocol deployment is more diffuse than previously believed and that protocols run on many additional ports beyond their primary IANA-assigned port.

A recent cryptographic solution Delphi (Usenix Security 2020) strives for low latency by using GPU on linear layers and replacing some non-linear units in the model at a price of accuracy. Meanwhile, a number of vulnerabilities and high-profile attacks against top EOSIO DApps and their smart contracts have also been discovered and observed in the wild, resulting in serious financial damages. Although SDN can improve network security oversight and policy enforcement, ensuring the security of SDN from sophisticated attacks is an ongoing challenge for practitioners. Finally, we use a state-of-the-art formal verification tool, Tamarin prover, to prove that 5G-AKA′ achieves the desired security goals of privacy, authentication and secrecy.

An email's authenticity is based on an authentication chain involving multiple protocols, roles and services, the inconsistency among which creates security threats. In this paper, we investigate cross-protocol attacks on TLS in general and conduct a systematic case study on web servers, redirecting HTTPS requests from a victim However, their pervasiveness also amplifies the impact of security vulnerabilities. While its reliability and cost effectiveness turned CAN into the most widely used in-vehicle communication interface, its topology, physical layer and arbitration mechanism make it impossible to prevent certain types of adversarial activities on the bus. These studies mainly focused on improving the utility of the LDP protocols. In the past several years, researchers from multiple communities—such as security, database, and theoretical computer science—have proposed many LDP protocols. , <2% in the Active learning is widely used in data labeling services to support real-world machine learning applications.
