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 advent of Spectre, a number of counter-measures have been proposed and
deployed. Rigorously reasoning about their effectiveness, however, requires a well-defined …

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

This paper presents Serval, a framework for develo** automated verifiers for systems
software. Serval provides an extensible infrastructure for creating verifiers by lifting …

Abstract Development of formal proofs of correctness of programs can increase actual and
perceived reliability and facilitate better understanding of program specifications and their …

We present the most complete and thoroughly tested formal semantics of x86-64 to date. Our
semantics faithfully formalizes all the non-deprecated, sequential user-level instructions of …

This technical report describes CHERI ISAv7, the seventh version of the Capability
Hardware Enhanced RISC Instructions (CHERI) Instruction-Set Architecture (ISA) being …

Leakage contracts have recently been proposed as a new security abstraction at the
Instruction Set Architecture (ISA) level. Leakage contracts aim to capture the information that …

Speculative vulnerabilities such as Spectre and Meltdown expose speculative execution
state that can be exploited to leak information across security domains via side-channels …

The Internet of Things (IoT) is an ongoing technological revolution. Embedded processors
are the processing engines of smart IoT devices. For decades, these processors were …
