Confidential Computing devroom @ FOSDEM 2026
Call for Participation

Sunday, February 1, 2026, 9am-1pm
Brussels, Belgium

Submission deadline: December 1, 2025

FOSDEM dates: January 31 & February 1, 2026

About FOSDEM

FOSDEM is a free event for software developers to meet, share ideas and collaborate. Every year, thousands of developers of free and open source software from all over the world gather at the event in Brussels. FOSDEM is free to attend. There is no registration.

Following the success of last years’ editions, we are for the 7th time organizing a devroom devoted to the emerging open-source ecosystem around hardware-based Trusted Execution Environments (TEEs), which nowadays is also known under the term confidential computing. The devroom will be co-located with FOSDEM 2026, the largest European event centered on free and open-source software development.

Devroom overview and objectives

Confidential computing leverages hardware-based TEEs in order to protect and secure data in-use. This devroom is devoted to this emerging free and open-source ecosystem around TEEs that allow to directly isolate and attest trusted “enclave” software components running on top of a potentially compromised operating system. Over the last years, all major processor vendors have developed some form of TEE support, e.g.,

  • ARM TrustZone, Morello & Confidential Computing Architecture (CCA)
  • AMD Secure Encrypted Virtualization (SEV) & SEV-ES/SEV-SNP extensions
  • IBM Secure Execution for Linux on Z (SEL).
  • Intel Software Guard Extensions (SGX) and Trust Domain Extensions (TDX)
  • NVIDIA GPUs

Hence, with today’s mainstream consumer hardware being increasingly shipped with these advanced trusted computing technologies, this devroom wants to foster discussion on the much-needed free and open-source TEE ecosystem amongst industry players, academics, enthusiasts, hobbyists, and project maintainers.

Desirable topics

The devroom’s topics of interest include, but are not limited to:

  • Open-source confidential computing.
  • An introduction to the existing solutions and the use cases they cover, etc.
  • Programming frameworks for TEEs: how to develop free and open-source software that can run inside enclaves (e.g., library OSs, SDKs, Linux kernel support, etc.).
  • Confidential computing deployment: Challenges and benefits.
  • Use cases and applications on top of TEEs such as applying confidential computing to the Cloud Native space.
  • Compiler and language support for emerging trusted hardware extensions.
  • Open-source enclave processor designs (e.g., RISC-V TEEs).
  • Attestation, focusing on Confidential Computing (see note below)
  • Existing technologies:
    • What do they have in common, how do they differ?
    • Which confidential computing use cases can they cover?
  • Upcoming technologies:
    • TEEs on accelerators (GPUs, NPUs, DPUs, etc)
    • Interaction between existing and upcoming technologies
    • Opportunities
  • Vision: future TEEs (what is missed, proposals, wishes, discussions).
  • TEE-specific attacks and defenses: reverse engineering, side-channels, vulnerabilities, exploits.

The devroom will be physical-only. Please note that we can give none to very limited support for speakers requiring a visa to enter Belgium, as us devroom organizers do not represent the broader FOSDEM conference and can not provide official visa invitation letters.

This year’s changes

This year, there is no dedicated developer room on attestation. Thus, any attestation topic can again fit into our confidential computing devroom if it benefits the wider trusted computing community.

Key dates (Brussels time)

  • Submission deadline: December 1, 2025 (The Fosdem Pretalx may state an earlier date but this is for the main track only. We will consider submissions up to and including December 1).
  • Announcement of selected talks: December 15, 2025
  • FOSDEM dates January 31 & February 1, 2026
  • Confidential computing devroom date: February 1, 2026, 9am-1pm

Submit a talk proposal

Submissions are required to proceed through the FOSDEM pretalx system.

Your submission must include the following information:

  • Proposal title of your talk: please be descriptive, as the audience will have to choose to attend your talk out of a listing with ~500 talks from other projects at FOSDEM.
  • Select “Confidential computing devroom” as the track.
  • A longer description if you wish to do so.
  • A short abstract of one paragraph.
  • Submission notes to let us know of specifics to your talk.
  • Additional speakers if you want to add them.
  • FOSDEM requires you to fill in which open-source license you use and to provide links to your source code. All talks at FOSDEM must be about free and open-source software, so please make it clear to the organizers by providing a public URL to the source code of the relevant project(s).In case the URL is not yet public, please indicate so and explicitly clarify your commitment to have the code available the latest at the time of the devroom.
  • Information about yourself.
  • Please note that we do not allow remote speakers. All speakers need to be at FOSDEM in-person.

We target a block of 20-40 minutes per talk (including Q&A).

If you wish to only give a shorter talk, you can let us know in the submission notes. We leave the option open to have several 10 minute talks for rapid-fire ideas and discussion points. Let us know in the submission notes if you plan your submission to be more interactive so that we can plan in more time for discussion after your talk.
