The advantages of virtualization technology have resulted in its wide spread adoption in
cloud computing infrastructures. However it has also introduced a new set of security threats …

Given the central role that C continues to play in systems software, and the difficulty of
writing safe and correct C code, it remains a grand challenge to develop effective formal …

We present Low*, a language for low-level programming and verification, and its application
to high-assurance optimized cryptographic libraries. Low* is a shallow embedding of a …

The C programming language was created by Thompson and Ritchie around 1970 as the
implementation language of the Unix operating system [Rit93]. The development of Unix …

We present a framework to generate verified LLVM programs from Isabelle/HOL. It is based
on a code generator that generates LLVM text from a simplified fragment of LLVM, shallowly …

This paper presents a framework aimed at significantly reducing the cost of proving
functional correctness for low-level operating systems components. The framework is …

Characteristic Formulae (CF) offer a productive, principled approach to generating
verification conditions for higher-order imperative programs, but so far the soundness of CF …

The ISO C standard does not specify the semantics of many valid programs that use non-
portable idioms such as integer-pointer casts. Recent efforts at formal definitions and verified …

We present a framework aimed at significantly reducing the cost of verifying certain classes
of systems software, such as file systems. Our framework allows for equational reasoning …

Experienced developers of safety-critical and security-critical systems have long
emphasized the importance of applying the highest degree of scrutiny to a system's I/O …
