This post focuses on Galois’s silicon projects and related research efforts around asynchronous circuit design as we approach the 27th IEEE International Symposium on Asynchronous Circuits and Systems (ASYNC 2021), to be hosted by Galois as a virtual conference September 7–10, 2021. In a recent blog post, we shared Galois’s interest in asynchronous circuit design. […]
Distributed protocols enable components such as blockchain validator nodes, cloud servers, or IoT devices to coordinate and cooperate toward a common goal. However, in such a diverse environment, a lot of things can go wrong: hardware can fail, software can be buggy, network links can be unreliable, attackers may compromise components, and so on. Due […]
Proofs are our bread and butter at Galois – we apply proofs to many different assurance problems, from compiler correctness to hardware design. Proofs and the theorem proving technologies that apply them are very powerful, but that power comes with a cost. In our experience, proofs can be difficult to maintain over time as systems […]
The title of our blog post may sound like a directive from a Dungeon Master, but it’s firmly rooted in Galois’s forward-thinking computer science. C/C++ code is the foundation of our most critical systems – even “new” systems nearly always incorporate legacy code. But this type of component reuse carries its own dangers because we […]
At Galois, we’re always looking for better ways to build reliable systems. A big part of that is doing our own research. At 130 people, we’re one of the world’s largest formal methods research teams! But another part of our work is understanding new tools and techniques from the research community. We’re interested in solving […]
The basilisk is a creature from legend that could permanently stop its adversaries with only a glance. Its venom was also described by Pliny the Elder as being able to run up the spear of an adversary and permanently end that threat, as well. Inspired by the legendary creature’s prowess at securing “the last mile” […]
In his 1900 book The Wonderful Wizard of Oz, L. Frank Baum tells a story that will resonate with any software engineer. A woodman by the name of Nick Chopper suffers a series of workplace accidents. In turn, his arms, legs, body, and even his head are replaced by metal prosthetics. Eventually, what remains is […]
This blog is the second in a series of posts about a joint project between Galois, Supranational, The Ethereum Foundation, and Protocol labs verifying the blst signature library. You can find the first post here. It’s a combination of my bad jokes and an overview of what we’re trying to achieve. It’s happening already. The […]
I’m happy to share something new the Galois cryptography verification team is working on in collaboration with the Ethereum Foundation, Protocol Labs, and Supranational. However, I’m sorry to inform you that Galois has sold out to dramatic live-blogging. We’ve sold out so much that I, unrequested by anyone, took the liberty of making us a […]
On Monday, the KRACK vulnerability to WPA2 was revealed in a paper by Mathy Vanhoef and Frank Piessens. KRACK enables a range of attacks against the protocol, resulting in a total loss of the privacy that the protocol attempts to guarantee. For more technical details on the attack, the website and the Key Reinstallation Attacks […]
