Computer-aided cryptography is an active area of research that develops and applies
formal, machine-checkable approaches to the design, analysis, and implementation of …

Since the discovery of Spectre, a large number of hardware mechanisms for secure
speculation has been proposed. Intuitively, more defensive mechanisms are less efficient …

We introduce Blade, a new approach to automatically and efficiently eliminate speculative
leaks from cryptographic code. Blade is built on the insight that to stop leaks via speculative …

Compilers assure that any produced optimized code is semantically equivalent to the
original code. However, even" correct" compilers may introduce security bugs as security …

Formal methods encompass a wide choice of techniques and tools for the specification,
development, analysis, and verification of software and hardware systems. Formal methods …

The current gold standard of cryptographic software is to write efficient libraries with
systematic protections against timing attacks. In order to meet this goal, cryptographic …

Verifying Hardware Security Modules with Information-Preserving Refinement Page 1 This paper
is included in the Proceedings of the 16th USENIX Symposium on Operating Systems Design and …

This paper presents a novel formal semantics, mechanized in Coq, for a large, sequential
subset of the LLVM IR. In contrast to previous approaches, which use relationally-specified …

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 …

High-assurance cryptography leverages methods from program verification and
cryptography engineering to deliver efficient cryptographic software with machine-checked …
