Course Description

Overview

Explore a comprehensive analysis of new cache attacks on TLS implementations in this IEEE Symposium on Security & Privacy presentation. Delve into the evolution of Bleichenbacher's padding oracle attack against RSA implementations, examining how most systems remain vulnerable to novel microarchitectural side channel attacks despite two decades of mitigation efforts. Learn about Cache-like ATacks (CATs) and their potential for downgrade attacks against TLS connections. Discover a new method for parallelizing Bleichenbacher-like padding attacks, enabling faster and more efficient exploitation of RSA implementations. Gain insights into the implications of these findings for TLS security and the broader field of cryptography.
