Analyzing and Exploiting Branch Mispredictions in Microcode
Nicholas Mosier, Hamed Nemati, John C. Mitchell +1
We present uSpectre, a new class of transient execution attacks that exploit microcode branch mispredictions to transiently leak sensitive data. We find that many long-known and re…
Serberus: Protecting Cryptographic Code from Spectres at Compile-Time
Nicholas Mosier, Hamed Nemati, John C. Mitchell +1
We present Serberus, the first comprehensive mitigation for hardening constant-time (CT) code against Spectre attacks (involving the PHT, BTB, RSB, STL and/or PSF speculation primi…
nl2spec: Interactively Translating Unstructured Natural Language to Temporal Logics with Large Language Models
Matthias Cosler, Christopher Hahn, Daniel Mendoza +2
A rigorous formalization of desired system requirements is indispensable when performing any verification task. This often limits the application of verification techniques, as wri…
Relational Models of Microarchitectures for Formal Security Analyses
Nicholas Mosier, Hanna Lachnitt, Hamed Nemati +1
There is a growing need for hardware-software contracts which precisely define the implications of microarchitecture on software security-i.e., security contracts. It is our view t…
