We are just finishing the second year of the Confidential Computing Consortium, and it is time once again to look back on what the members have accomplished together. 

Membership & Project Growth

All of our meetings start with the reminder that all members are welcome and all projects are welcome. It have been this way since we launched. 

Remember that companies create non-profits like the Consortium in the broad open source space because our businesses benefit from that membership, and from working together towards common goals. We launched the Consortium with 15 premier and general members, growing to 27 corporate members and 2 non-profits by the end of the first year. While we lost a few members this year as company priorities shift, we have continued to grow to 36 corporate members and 4 non-profits over this past year. 

This year we welcomed the following companies to the Consortium: 

Ampere, Applied Blockchain, Baidu USA, Canary Bit, Cisco, Crust, Edgeless, En|viel, Ethernity Cloud, HUB Security, Madana, Opague Systems Inc, Phalla Network, Technology Innovation Institute, Western Digital, Xilinx. 

Our newest general member last week is Profian. The addition of general members through the year brought us over the twenty mark and we added a new general member representative to the governing board (Eric Voit, Cisco). 

A primary part of our shared mission is to support open source and standards projects relating to confidential computing to accelerate the acceptance and adoption of confidential computing in the market. This year the Consortium welcomed four new projects:

  • Keystone: Keystone is an open-source project for building trusted execution environments (TEE) with secure hardware enclaves, based on the RISC-V architecture. Our goal is to build a secure and trustworthy open-source secure hardware enclave, accessible to everyone in industry and academia.
  • Veracruz: Veracruz is a research project exploring the design of privacy-preserving distributed systems.  Veracruz uses strong isolation technology and remote attestation protocols to establish a “neutral ground” within which a collaborative, multi-party computation between a group of mistrusting principals takes place.
  • Gramine: Gramine is a rebranded Graphene project. A particular use case for Gramine is Intel Software Guard Extensions (SGX), where applications do not work out-of-the-box. Gramine solves this problem, with the added security benefits. Gramine can serve as a compatibility layer on other platforms.
  • Occlum: Occlum makes running applications inside enclaves easy. It allows one to run unmodified programs inside enclaves with just a few simple commands.

The Technical Advisory Council (TAC)

The Technical Advisory Council continues to meet every other week. It is an opinionated public debate and everyone is welcome to attend. Members in the TAC saw the need to begin to add some structure and this year created the idea of Special Interest Groups (SIG) as they put in place the Attestation SIG. It was recognized by members that attestation will become the next challenge in confidential computing and have begun the discussion of how best to enable TEE attestation across the industry. 

The TAC membership also published a more detailed Technical Analysis of Confidential Computing white paper.

The Outreach Committee

Outreach Committee members were also busy this year in their collaboration. The Consortium Webinar Series has been building with monthly entries covering our projects and topics that span our domain. This is a good quick way to get an introduction to projects as each project has contributed to the collection. 

A global pandemic makes it tough to gather together, but this year the members organized and ran the first Confidential Computing Developer Summit, C2DS in June. It was run as a virtual unconference with a full day of content. There was good attendance with 400 registered developers participating through the day. All the feedback was good and the team looks forward to building an event again this coming year. 

The Outreach Committee commissioned an analyst group to produce a market study this year. Working with members, the analysts have built a view of the confidential computing industry in its growth. The study will be published this month. 

Lastly, Outreach Committee members have been working towards launching an End User Advisory Council to attract broader input into how users of confidential computing technology see the challenges ahead. We had hoped to launch the advisory council at the Linux Foundation Open Source Summit in September, but pulled back as people continue to be cautious with pandemic travel. Look for a launch in the near future. 

Outreach is working with the Linux Foundation creative staff to improve the Consortium website and we will be rolling changes out soon.

General Administrivia

I have long joked that governing boards should be boring places voting on meeting minutes, money, and membership. 

  • In keeping with that intent, we continue to run a healthy budget surplus as working committees spend money cautiously in a pandemic. 
  • We reviewed and tuned our charter last year in the Fall. As members continued to evolve our transparent, collaborative endeavor together, they had suggestions for tweaks to the charter that were voted last Fall. We will open the charter again shortly to see what new changes will be proposed. In making this an annual practice, it becomes an easy muscle to exercise, and debates don’t become worrisome and contentious. 

We continue to get great support from the Linux Foundation services teams. Stephano Cetola has recently moved to become a technical director at the RISC-V organization. While we are sad to see him go, Brian Warner is stepping into the role of Linux Foundation program manager. This year Ashley Weltz joined the program management team to help put the developer summit and end user advisory council in place. 

I look forward to continue working with all of our members in the coming year. A number of new projects have approached the Consortium. New members continue to express interest. It should be an exciting year ahead. 

Updated January 2022 to reflect new members joining in Q4 of 2021.
