TII logo

The seL4 Foundation thanks TII for becoming a Gold sponsor of the seL4 Summit 2023.

The Technology Innovation Institute’s (TII) Secure Systems Research Centre (SSRC) aims to drive end-to-end security and resilience in cyber-physical and autonomous systems that will ensure safety. The research center adopts an applied research approach, emphasizing practical applications. By employing seL4 as both a microkernel and a hypervisor, SSRC seamlessly aligns its dedication to security with the foundational technology crucial to achieving its objectives. This critical technology forms the cornerstone of secure software stacks for diverse edge devices, including secure communicators and drones. TII's research not only contributes to but propels the evolution of cutting-edge high-end edge device environments. TII's SSRC focus centers on resilience, isolation, trust, and security, all with the intention of fostering a more secure digital landscape.

Kry10 logo

The seL4 Foundation thanks Kry10 for becoming a Gold sponsor of the seL4 Summit 2023.

Kry10 offers a full-featured operating system on top of the seL4 kernel, along with tooling, services, key management and more. The Kry10 Platform is a fast and easy way to build highly secure, next-generation cyber-physical devices. It leverages the verification of seL4 to provide a secure, self-healing, truly dynamic system with minimal downtime, even during upgrades.

Kry10 is an Endorsed Service Provider of the seL4 Foundation, offering support to enable seL4-based secure projects to be affordable, maintainable, and remotely manageable.

Collins Aerospace logo

The seL4 Foundation thanks Collins Aerospace for becoming a Silver sponsor of the seL4 Summit 2023.

Collins Aerospace, part of seL4 Foundation member Raytheon Technologies, has been a long-time core participant in the seL4 ecosystem. It was a prime contractor in the DARPA HACMS program, which demonstrated the seL4-based incremental cyber retrofit of autonomous military vehicles. This was a major milestone in the growth of seL4, demonstrating that it protects against cyber attacks on real systems in operation. The same team also led the follow-on DARPA CASE program, aiming at designed-in cyber-resiliency, including the seL4-based framework for verified initialisation and configuration of systems architectures.

The seL4 Summit 2023 will take place in Minneapolis, home town of this Collins Aerospace team involved in seL4.

NIO logo

The seL4 Foundation thanks NIO for becoming our first Gold sponsor of the seL4 Summit 2023.

NIO is a global EV company funded in 2015 and that went public in the U.S. in 2018. NIO emphasizes user experience and technology innovation. NIO is a strong supporter of seL4 and a premium member of the seL4 Foundation. It has been investing heavily on building a full-fledge software platform for modern vehicles based on seL4.

seL4 summit

Have a look at the program of the seL4 summit 2023! We have a great line-up of interesting seL4 work, with a combination of technical research and development, experience reports of seL4 in the field, technical discussions and birds-of-a-feather sessions, as well as a training session on getting started with seL4.

seL4 summit 2023 program

We are pleased to announce that the two keynotes for the seL4 summit 2023 will be Gage from NCSC and Sam Leffler from Google! Gage will talk about Scoping assurance activities with seL4 and Sam about CantripOS: An OS for Ambient ML Applications.

NCSC logo

Gage is an Assurance Lead in NCSC with expertise in cryptography, software assurance and verification. He is part of a larger team that seeks to provide assurance and articulate risk for a wide range of products and customers. Whilst he is not a product developer himself, he has been responsible for presenting assurance cases for products that rely on seL4 to uphold security requirements.

Google logo

Sam Leffler has worked at Google for nearly 15 years. He was part of the original team that developed ChromeOS and the ChromeBook, was responsible for the networking components of Project Loon, and worked on various infrastructure projects before joining Project Sparrow to help build the CantripOS embedded operating system. Prior to joining Google he was an independent contractor focused on wireless networking and operating systems. Before contracting he worked for VMware, Silicon Graphics, Pixar, Lucasfilm, and the Computer System Research Group (CSR) at UC Berkeley where he was responsible for the 4.2BSD release of the UNIX operating system. At CSRG he co-designed and implemented many of the facilities found in contemporary UNIX systems including sockets, networking support (IP/TCP), reliable signals, and more.

Galois logo

We are pleased to have Galois now part of the seL4 Foundation, following its acquisition of Adventium labs, which has been a member since 2020 and user of seL4 technologies for years before that. Galois develops technology to guarantee the trustworthiness of systems where failure is unacceptable. They apply cutting edge computer science and mathematics to advance the state of the art in software and hardware trustworthiness. The seL4 Foundation looks forward to our continuing collaboration.

ACM Award Winners

The 2022 ACM Software System Award recognises seL4 as the first industrial-strength, high-performance operating system to have been the subject of a complete, mechanically-checked proof of full functional correctness, proofs of enforcement of the core security properties of integrity and confidentiality, a proof to the binary code of the kernel, and the first sound and complete worst-case execution-time analysis of a protected mode OS.

The award, recognising the development of a software system that has had a lasting influence, goes to Gernot Heiser, University of New South Wales; Gerwin Klein, Proofcraft; Harvey Tuch, Google; Kevin Elphinstone, University of New South Wales; June Andronick, Proofcraft; David Cock, ETH Zurich; Philip Derrin, Qualcomm; Dhammika Elkaduwe, University of Peradeniya; Kai Engelhardt; Toby Murray, University of Melbourne; Rafal Kolanski, Proofcraft; Michael Norrish, Australian National University; Thomas Sewell, University of Cambridge; and Simon Winwood, Galois.

We are committed to make sure that seL4's recognised "lasting influence" live on for the decades ahead!
