By Blog, Newsletter

Welcome to the February 2023 edition of the Confidential Computing Consortium newsletter! We look forward to sharing every month news about projects underway, new members, industry events and other useful information to keep you updated with what’s happening at the consortium.

Recent Events

FOSDEM

The Confidential Computing Consortium participated at the Confidential Computing devroom at FOSDEM on the 4th and 5th of February. The event was organized by Jo Van Bulck and Fritz Alder, from the University of Leuven, Belgium, and Fabiano Fidencio, from Intel. This was the fourth edition of this devroom at FOSDEM. The event was very successful. The devroom, with a capacity for 80 attendees, was mostly full throughout the day. Half of the people in the devroom have heard of Confidential Computing and many of the speakers were members of the CCC. Jo and Fritz highlighted the importance of bringing developers and academia together around Confidential Computing. There was also a social event organized by Richard Searle, Chair of the EUAC.

State of Open Con


The Confidential Computing Consortium participated at the State of Open Con in London on the 7th and 8th of February. This was the first conference of its kind being organized by OpenUK and it was located at the Queen Elizabeth II Centre, in the heart of London. Amanda Brock, the Executive Director of OpenUK, kicked off the event with a keynote. Other keynote speakers included Jimmy Wales, Founder of Wikipedia, Camille Gloster, Deputy National Cyber Director from the White House, and Eric Brewer, VP Infrastructure & Google Fellow. The CCC had a booth where Nick Vidal, the CCC Outreach Chair, was joined by Liz Moy (Evervault). There was good engagement at the booth, with the presentation of demo use cases that resonated with attendees. Stephen Walli, the CCC Chair, was also present and gave a talk entitled “What do we mean by Open Governance?” Mike Bursell, co-founder of the Enarx project, gave an entertaining talk on ConfidentialComputing.

CCC Webinar: Confidential Computing in Financial Services

Upcoming Events

OC3

The Confidential Computing Consortium is a sponsor of the Open Confidential Computing Conference (OC3). The online conference will take place on the 15th of March. Registration is free. Stephen Walli, Chair of the CCC, will give one of the keynotes. The main keynote “Industry Perspectives: the impact and future of confidential computing” features Ian Buck, VP of Hyperscale and HPC at NVIDIA, Mark Papermaster, CTO & EVP at AMD, Mark Russinovich, CTO at Microsoft Azure, and Greg Lavender, CTO of Intel.

Confidential Computing Summit

The Confidential Computing Consortium is a co-organizer of the Confidential Computing Summit. The event will take place in San Francisco on the 29th of June. The Confidential Computing Summit brings together experts, innovators, cloud providers, software and hardware providers, and user organizations from all industries to accelerate key initiatives in confidential computing. Call for Speakers are open.

White Papers & Reports

The National Cybersecurity Center of Excellence (NCCoE) has released a draft report, NIST Interagency Report (NISTIR) 8320D, Hardware Enabled Security: Hardware-Based Confidential Computing, for public comment. The public comment period for this draft is open through April 10, 2023. Abstract from the report: In today’s cloud data centers and edge computing, attack surfaces have shifted and, in some cases, significantly increased. At the same time, hacking has become industrialized, and most security control implementations are not coherent or consistent. The foundation of any data center or edge computing security strategy should be securing the platform on which data and workloads will be executed and accessed. The physical platform represents the first layer for any layered security approach and provides the initial protections to help ensure that higher-layer security controls can be trusted. This report explains hardware-enabled security techniques and technologies that can improve platform security and data protection for cloud data centers and edge computing.

Technical Advisory Committee

As part of 2023 goals, the TAC is looking to increase the impact of the CCC in the ecosystem:

  • Cross-project Integration event for discussion.
  • Portfolio growth and maturity, hosting projects that are adopted by the community. Look into new projects from member companies and academic research.
  • Cross-org and Cross-SIG coordination.
  • Outbound education and DCI revisit.

– Dan Middleton, TAC Chair (2023)

Outreach Committee

The CCC Outreach Committee has brought in Jake Orlowitz (WikiBlueprint) as the Wikipedia consultant with the goal of facilitating the creation of a top-quality Wikipedia article on Confidential Computing on English Wikipedia using an efficient participatory approach. As a result of this collaborative participation, Mike Ferron-Jones (Intel) has shared a Wikipedia article draft.

The CCC Outreach Committee has also brought Noah Lehman (Linux Foundation) as a social media consultant with the goal of facilitating the creation of top-quality posts on Twitter and LinkedIn. In collaboration with CCC members, he’ll create up to 8 on-demand social posts per month (this includes social posts promoting ad-hoc announcements, events, news and initiatives) and up to 4 on-demand social posts per month shared on Linux Foundation social media. Noah has shared the Social Media plan with the CCC.

Kate George (Intel) has volunteered to help with the CCC Event Strategy. She highlighted 5 event objectives: 1. Raise awareness of Confidential Computing & Open-source projects under the foundation, and participating companies; 2. Accelerate the adoption of Confidential Computing; 3. Present panels, talks, and demo cases to targeted audiences – security, health care, financial services, and government. (Consider compliance piece too); 4. Recruit new members or projects; and 5. Foster collaboration and open-source. Kate and Nick Vidal have shared the Event Strategy slides and List of Events.

Projects

Enarx

The Enarx project is looking for a custodian, as Profian had to close its doors. Both Profian and Red Hat have invested heavily on the development of Enarx, which has reached a good stable release with a number of key components to establish the foundations for a comprehensive Confidential Computing solution. The Linux Foundation is providing full support to the project.

Gramine

Gramine version 1.4 has been released, with important new features, including support for EDMM (Enclave Dynamic Memory Management), and performance improvements. Key milestones for 2023 include support communication with hardware accelerators (GPUs), support dynamic thread creation/destruction, support additional runtimes and workloads, integration with confidential container deployments (Kata containers, enclave-CC), interoperate with RA-TLS (standardization), support additional TEE backends (Intel TDX), and explore coarse-grained partitioning for certain I/O bound applications (DPDK).

Keystone

Keystone aims to enable TEE on (almost) all RISC-V processors. It’s very popular in academia, gaining 133 yearly citations (+28% YoY), however in the past year four students from UCB working on Keystone have graduated and left the project. Key milestones for 2023 include better application support (dynamic library), parity with industry standards, increase dev board accessibility, and work closely with the RISC-V AP-TEE working group.

White Papers & Reports

The Confidential Computing Consortium has published the Common Terminology for Confidential Computing. As more companies and open source projects begin to use similar terms to describe similar paradigms that build upon hardware-based, attested Trusted Execution Environments (TEEs), it will be increasingly important that vendors use consistent terminology that describes the ways in which these new capabilities are applied within different functional domains.

Technical Advisory Committee

It was a busy year for the Technical Advisory Council (TAC). We had a number of goals for the year across the spectrum of maturing our projects to collaborating with other open organizations to acting on our diversity & inclusion plans. Attestation was a pronounced theme for the year. We revised the definition of Confidential Computing to include attestation as an essential element. The TAC approved the Veraison project which focuses on building blocks for attestation verification. We created the Attestation SIG last year and throughout 2022, it found its legs and created a good deal of content. You can browse our meeting recordings and presentations for a series of talks on Secure Channels and Attestation Formats. An outcome of this sharing led to two additional initiatives. CCC projects Gramine, Occlum, and Open Enclave SDK all rely on separate implementations of “Remote Attestation TLS.” The independent implementations were not interoperable. The Attestation SIG helped uncover and resolve variations arriving at a proposal to harmonize the implementations of those projects. Contributors to the SIG are also creating an Attested TLS proof of concept based on a similar design. We look forward to attestation of TEEs becoming a fundamental part of communications as Confidential Computing becomes pervasive.

Harmonization was not unique to the Attestation SIG. The TAC also engaged with a variety of organizations looking for opportunities for collaboration and coordination. We hosted speakers from RISC-V, MPC Alliance, IETF, TCG, CDCC, TrustedComputing.org, HomomorphicEncryption.org, PCI SIG WG, and the OCP Security SIG. In fact, most of our TAC meetings host a Tech Talk and our meetings have become a place for learning a variety of security related technical topics. As an open collaborative community, everyone is welcome to join our meetings or view the recordings. We hope to see you in one in 2023.

The TAC also had direct collateral outputs. In addition to revising our primary whitepaper, we also generated a new whitepaper which is going through final layout. That paper focuses on terminology to give greater clarity to the different ways Confidential Computing artifacts can be packaged and what that should imply to a consumer. We were also able to collectively form a response to the OSTP’s request for comments on Privacy Enhancing Technologies (PETs).

This government interaction suggested a broader need for similar discourse. The TAC subsequently approved the creation of a Governance, Risk, and Compliance SIG. This newly chartered SIG already has representation from representatives from Meta, Microsoft, Intel, NVidia, Arm, CSA, JPMorgan Chase, Anjuna and others.

Of course, as an open source organization, our main focus is on open source projects. This year the TAC provided projects with additional resources. Our focus on diversity and inclusion took a few forms. Each of the projects were introduced to D&I training specifically for open source provided by the Linux Foundation. We made Outreachy internships available and Veracruz and Enarx piloted this membership program for the rest of the CCC. As the year progressed we created other resources for projects – increasing funding for CI, creating conference travel funding for projects, and making additional security tooling available.

All in all it has been a very productive year for the Technical Advisory Council, our SIGs, and our projects. We have a number of ambitious goals coming together for 2023 and will communicate those in a future blog.

Outreach Committee

2022 was a year of two halves. While the effects of COVID restrictions were still being felt in the first half of the year, things really turned around in the summer, and by the end of the year life was back to pre-COVID levels in most regions of the world. The outreach committee had to be nimble and adapt to the changing circumstances. In some ways, some of the impetus was to lay the foundation to hit the ground running again in 2023.

The committee implemented multiple important initiatives during this time including:

  • For the second year in a row, CCC sponsored the OC3 Summit, a virtual Open Confidential Computing Conference held in early 2022.
  • Building brand awareness and visibility in industry events like RSA. We were able to negotiate a co-marketing arrangement at no cost, whereby RSA promoted the CCC on their website, and in promotions, and CCC did the same for RSA. We’ll have a similar arrangement with RSA in 2023 as well.
  • Expanding our presence to Latin America, participating at Roadsec 2022 in Sao Paulo, the biggest hacker festival in Latin America. 
  • After a hiatus due to COVID, CCC had a presence at Black Hat USA, in Las Vegas. This included a meeting room where we received visitors wanting to learn and/or get engaged with CCC. In addition we also got exposure in some of the member booths at the show, by way of presentations, CCC handouts etc.
  • We were also able to get brand visibility at the Crypto & Privacy Village at DEF CON 2022.
  • Rekindled industry analyst interactions including recent briefing with ABI Research, and communications with Gartner, Forrester, IDC, 451 Research, OMDIA, Nemertes and other Tier 2/3 analyst firms
  • Secured a speaking spot for the consortium in the Keynote segment of the upcoming OC3 event in March 2023
  • Signed up a consultant to greatly increase our social media activities starting Jan 2023
  • Shortlisted a consultant to help guide the committee to get Confidential Computing on Wikipedia
  • Made good progress on content refresh of our website, with the updates scheduled to be rolled out in March 2023

The committee is very excited about the foundation that has been laid, and we are looking forward to a highly successful 2023!
