Tech talk: Internet of Things: From Small- to Large-Scale Orchestration

abstract: The domain of Internet of Things (IoT) is rapidly expanding beyond research and becoming a major industrial market with such stakeholders as major manufacturers of chips and connected objects, and fast-growing operators of low-power wide-area networks. Importantly, this emerging domain is driven by applications that leverage the infrastructure to provide users with innovative, high-value […]

CyberChaff at Reed College

Formaltech, a Galois subsidiary, and Reed are excited to celebrate CyberChaff’s first month of service at Reed. Formaltech’s CyberChaff allows you to deploy low-cost, secure decoy hosts on a network. The hosts alert administrators when an attacker is detected while also slowing down key steps in the attacker’s workflow. In March, Galois and Formaltech engineers […]

Tech talk: Interrupts in OS code: let’s reason about them. Yes, this means concurrency.

abstract: Existing modeled and verified operating systems (OS’s) typically run on uniprocessor platforms and run with interrupts mostly disabled. This makes formal reasoning more tractable: execution is mostly sequential. The eChronos OS is a real-time OS used in tightly constrained devices, running on (uniprocessor) embedded micro-controllers. It is used in the DARPA-funded HACMS program, where […]

Galois Announces ISC: The Imperfect Stitch Compiler

This was an April Fool’s post published on April 1, 2016. The Imperfect Stitch Compiler is a fictional product. Galois is known for building perfect software. But is our software too perfect? The imperfect stitch, or Persian flaw, is a deliberate error in an otherwise perfect work of art. The term derives from the proverb, […]

Tech talk: Adversarial Machine Learning, Privacy, and Cybersecurity in the Age of Data Science

abstract: Due to the exponential growth of our ability to collect, centralize, and share data in recent years we have been able tackle problems previously assumed to be insurmountable. Ubiquitous sensors, fast and efficient machine learning, and affordable commercial-off-the-shelf technologies have not only deepened our understanding of our world, but also democratized these capabilities. As […]

Tech talk: Toward Extracting Monadic Programs from Proofs

abstract: The Curry-Howard Isomorphism motivates the well known proofs-as-programs interpretation. Under that interpretation, sufficiently different proofs yield different programs. This work is a step toward extracting monadic programs from proofs. In working with the list monad as a motivating example, we discovered that the standard type bind (M a -> (a -> M b) -> […]

Galois: 2015 highlights

2015 was an active and productive year at Galois. From numerous awards, to new projects and spin-offs, to a vast array of publications and talks, Galwegians contributed to a wide range of fields this year. In this post, we highlight some of the contributions we made in 2015.
