2019 marked another eventful year for Galois, publishing 15 papers, sharing 26 talks, and announcing several large project awards. It seems cliche, but it’s true: our partners and collaborators play a central role in all of our work. We’re very grateful to be part of such a great community.
Below, we highlight some of the contributions we made in 2019.
2019 was another eventful year for the technical area of secure computation. We announced a $15 million partnership with IARPA to make secure computation, the process of working with data without ever exposing it, accessible to data scientists and other programmers who are not experts in cryptography. We continued to demonstrate and discuss the practical uses of secure computation through numerous talks and publications. We also spoke about using differential privacy to analyze data without revealing information about individuals.
This year, we kicked off a public hardware red-teaming effort at DEF CON to evaluate the security of DARPA SSITH processors, which aim to protect systems against classes of hardware vulnerabilities exploited through software. The red-teaming effort seeks to allow hackers to perform their own security evaluations on mock demonstration systems of the hardware prototypes. Secure processors would address a critical area of concern for DoD and industrial users alike: hardware vulnerability attacks.
In the area of software correctness, we continue to collaborate with Amazon Web Services (AWS) to verify the correctness of security-critical cloud infrastructure. We spoke about model-driven testing approaches used to find and remediate high-priority bugs in key software used to communicate with hardware security modules (HSMs). We also shared a significant number of talks and publications on formal verification, programming language design, type theory, and other programming language concepts.
Additionally, we launched Muse Dev, a spin-off company focused on developing tools that help you find critical bugs early in the development process. Muse Dev is serving a number of early, private beta customers. We have shared a number of talks that illustrate the problems the Muse Dev team is tackling.
Relating to cybersecurity, we announced a $8.6 Million contract awarded as part of DARPA’s CHESS program to build a cyber reasoning tool for vulnerabilities. We have partnered with Harvard University and Trail of Bits and aim to build scalable and more cost-effective tools that identify hard-to-find vulnerabilities.
The team behind our elections security spin-off, Free & Fair, partnered with Microsoft’s Defending Democracy program to develop and release the ElectionGuard SDK. ElectionGuard is a software development kit that enables end-to-end verifiable elections technology. It is open source and available for anyone to use and deploy.
As we tackled that exciting work, the health of the Galois community was a major focus for us in 2019. We strive to improve how we work together. Among other things, this year we reevaluated parental leave, making it 16 weeks for all new parents, and pursued an increased focus on ensuring an inclusive workspace and company activities. On Life at Galois, we share details about how we organize ourselves, which we consider to be a staple of our well-being at Galois. We added some fun ‘color’ relating to our role of Project Lead at Galois and what it entails.
Below you’ll find links to the papers, talks, and other public contributions we made in 2019, as well as other miscellaneous news. We hope you find something interesting.
From all of us at Galois, we wish you a happy 2020.

Language Oriented Programming, WG 2.16
Dr. Iavor Diatchki gave a talk on monads at the Working Group on Programming Language Design (WG 2.16). From the abstract: “A common programming idiom in Haskell is that of a “monad”–a concept often considered to be quite difficult to understand for programmers familiar with other languages. In this talk I will introduce “monads” using terminology that is likely to be familiar to language designers, and argue that they provide an interesting way of structuring programs in any language. Furthermore, the experience of using monads in Haskell has identified a number of useful abstractions, which may form the basis for a new programming language design.”
Dr. David Thrane Christiansen, Dr. Iavor S. Diatchki, Dr. Robert Dockins, Dr. Joe Hendrix, and Dr. Tristan Ravitch presented Galois’s experiences using advanced Haskell type system features in the development of Crucible, a general framework for writing symbolic simulators, at the 24th ACM SIGPLAN International Conference on Functional Programming.

Robust, Assured Diversity for Software Systems, RRTO Moving Target Defense Solutions
Dr. Benjamin Davis presented our automated software diversity research and variant generation technology, and how it can protect software systems by detecting and recovering from common classes of cyber attacks at Rapid Reaction Technology Office (RRTO) Moving Target Defense Solutions event. Our range of practical binary-rewriting- and compiler-based capabilities take an application to defend and automatically generate multiple variants that each behave detectably differently when under attack. Our research revealed cases where randomization-based approaches do not compose and naive layering of techniques end up negating the protections they were intended to add. Instead of randomizing blindly, we use formal reasoning to guide the layout of code and data in our variants to produce sets that maximize the chance that an attack causes observable discrepancies in variant behavior. To learn more about our approach, see this tech report on the topic.
