The Confidential Computing DevRoom at FOSDEM brought together experts and enthusiasts to discuss and demystify the rapidly evolving field of Confidential Computing. The event was a melting pot of ideas, showcasing the latest advancements, practical applications, and the future direction of this technology.
Kickoff: Unveiling the Essence of Confidential Computing
The DevRoom opened with Fritz Alder, Jo Van Bulk, and Fabiano Fidencio welcoming attendees and setting the stage for the day’s discussions. They emphasized the importance of adhering to the Confidential Computing Consortium (CCC) definition, highlighting key properties such as data confidentiality, integrity, and code integrity. The conversation also touched on contextual properties like code confidentiality, authenticated launch, and attestability, underscoring the diversity in application needs and security requirements.
Intel TDX: A Leap Towards VM Isolation
Dr. Benny Fuhry took the stage to deep dive into Intel Trusted Domain Extensions (TDX), presenting it as a groundbreaking approach to VM isolation. Intel TDX stands out by ensuring that each trust domain is encrypted with a unique key, a move aimed at mitigating Virtual Machine Monitor (VMM) attacks. With general availability announced alongside the 5th Gen Intel Xeon Scalable processors, Intel TDX is set to revolutionize memory confidentiality, integrity, and key management.
SGX-STEP: Enhancing Side Channel Attack Resolution
The SGX-STEP presentation from Luca Wilke spotlighted innovative techniques to counteract side-channel attacks, still a concern in the realm of Confidential Computing. Through detailed explanations of single stepping, interrupt counting, and amplification, the speakers shed light on improving temporal resolution for side-channel attacks, presenting a clear path toward more secure environments that could be used in Confidential Computing and beyond.
Database Security: Bridging Confidential Computing and Data Storage
Ilaria Battiston and Lotte Felius delved into the integration of confidential computing with database systems, presenting their research on secure databases. They discussed the performance overhead of utilizing SGX with SQLite and PostgreSQL, emphasizing the trade-offs between security and efficiency with preliminary results. Their work on minimizing performance impacts through vectorized processing inside secure enclaves provided valuable insights for developers aiming to secure database operations.
Evervault’s presentation from Cian Butler highlighted their innovative solutions for data security and compliance, focusing on encryption proxies and secure serverless functions. They discussed the challenges of monitoring and observability within AWS Nitro enclaves, showcasing their efforts to enhance reliability and performance in secure computing environments.
Tymoteusz Burak introduced the concept of fTPM implemented as a Trusted Application in ARM TrustZone, offering a compelling solution for enhancing the security of embedded systems. Despite challenges such as lack of secure storage and entropy sources, fTPM stands as a testament to the potential of leveraging Trusted Execution Environments (TEEs) for robust security measures.
The presentation by Tom Dohrmann on Mushroom offered an insightful look into securing Linux workloads using AMD’s SEV-SNP technology. With a clear goal to run Linux programs securely, Mushroom addresses the critical need for integrity in remote code compilation on untrusted hosts. The architecture of Mushroom, built with a focus on minimalism and security, comprises a kernel and a supervisor, both developed in Rust, emphasizing efficiency and reduced host interaction.
The talk by Malte Poll and Paul Meyer delved into a critical aspect of Confidential Computing: the validation of Trusted Computing Base (TCB) measurements through remote attestation and the importance of reproducible builds in this process. The presentation highlighted the challenges in the current landscape, where reference values for validating TCB measurements are often provided by third parties without transparent mechanisms for auditing their trustworthiness or origin. Advocating for an auditable CC ecosystem, the speakers emphasized the necessity for every component of the TCB to be open source and reproducible, allowing end-users to verify the deployed system comprehensively. Utilizing mkosi and Nix(OS), they showcased how to build fully reproducible OS images from source code to reference values for remote attestation, providing a foundation for projects like Constellation and the Confidential Containers project. This approach aims to enhance the trust and security in Confidential Computing by enabling the community to independently verify reference values, marking a significant step towards more transparent and secure computing environments.
Ionut Mihalcea and Thomas Fossati showed us the development and importance of remote attestation covered milestones from the formation of TCPA to the latest advancements in RATS EAT. This narrative underscored the critical role of remote attestation in establishing trust and preserving privacy within confidential computing frameworks.
FOSDEM concluded with a roundup of various DevRooms, highlighting the interconnectedness of confidential computing with other domains such as energy, community development, and monitoring. Special attention was given to the EU’s new open-source cloud initiative, IPCEI-CIS, showcasing the commitment to leveraging open-source solutions for enhancing security and privacy.
A Special Thank You
As we reflect on all the experiences and exchanges at FOSDEM, we want to share a special note of gratitude to all participants of the Decrypted Gathering – one that we received directly from the catering team who worked with us that night:
“
I catered your event and I have to thank you for having been the most respectful and polite clients I’ve ever seen… And I of course thank you for working for such a noble cause that is data protection and open OS.
Thank you for existing and you can congratulate all the persons present. It was unseen and so heartwarming for me/us.
All the best,
Lauréline
”
Confidential computing is unique. It’s the kind of work that anyone can understand the value of, as soon as you explain the kind of data we try to keep private. Personalized medicine, space technology, and energy grids are all parts of Confidential Computing’s emerging sectors.
I’m incredibly grateful to have a growing community of engineers, academics and technology giants all coming together around this work. Thank you to everyone who is helping us to bring Confidential Computing to the center stage of this year.

All of our technical committee meetings are open to the public, and recorded for all to view. We welcome anyone who wants to join in on the conversations around Confidential Computing.
If there’s a concept or clarification from these talks you believe is important to share with the CCC community, get in touch with me at skimmich@contractor.linuxfoundation.org and we’ll help you do write it up as a blog post or webinar, and get the information out to everyone.
The Linux Foundation’s Confidential Computing Consortium (CCC) is proud to announce Sal Kimmich joining as the Technical Community Architect. Sal’s career started by sharing Python scripts with other computational neuroscientists in the wild world of supercomputing. A decade later, they are still paying attention to the algorithmic side of open source tech.
Before joining CCC, Sal worked as a scalable SecDevOps Machine Learning engineer and brought those contributions to the Cloud Native Computing Foundation (CNCF) and the Open Source Security Foundation (OpenSSF). They have focused on practical automation around security best practices that make the maintainer’s lives easier, like Security Slams.
At CCC, we are building the landscape for Trusted Execution Environments (TEEs) at the Linux Foundation as it becomes as Confidential Computing becomes foundational to cross-industry security practicesConfidentiality of data in use is also a cornerstone of digital progress: having hardware level trust in compute is critical to the wave of critical technologies in both edge and cloud.
Sal’s vision for CCC is clear – to make maintainers’ work enjoyable and rewarding, to create tech demos that dazzle, and to showcase the world-class Open Source Projects enabling secure computation. 2024 marks the start of an incredible year of compute, collaboration and community expansion ahead, as runtime security takes the spotlight in emerging tech.
We’re excited to announce some recent attestation news. One of the hallmarks of confidential computing is the ability to build trusted communication with an application running in a hardware-based trusted execution environment. To make attestation easily accessible it can be incorporated into common protocols. That way developers don’t need to figure out all the details to build a secure protocol themselves. One of these protocols is called Remote Attestation TLS (RA-TLS), which builds on the ubiquitously used Transport Layer Security protocol underlying most secure internet communication. It turns out several projects independently implemented RA-TLS with tiny but incompatible differences. In the CCC Attestation SIG, we’ve agreed on and, in some cases, already implemented changes to make them all be able to interoperate.
The CCC Attestation SIG is chartered to develop attestation-related software aimed at improving interoperability, and to achieve harmonization and de-fragmentation between multiple projects. One approach is to identify and review projects in SIG meetings, propose improvements for interoperability and standardization, and work with these projects for implementation and tests. Interoperable RA-TLS is a great example showcasing how the SIG delivers on its charter.
RA-TLS (Remote Attestation TLS) architecture is defined in the white paper Integrating Remote Attestation with Transport Layer Security, to enable Intel® Software Guard Extensions (Intel® SGX) remote attestation during the establishment of a standard Transport Layer Security (TLS) connection. In a TLS server / client scenario, the TLS server runs inside an SGX enclave. It generates a public-private keypair, creates an SGX report with a hash of the public key in its user-data field, and gets an SGX quote for this report. It then creates an X.509 certificate with a custom extension containing this SGX quote. This customized certificate is sent to a TLS client in the TLS handshake protocol. The client gets the SGX quote from the certificate and performs remote attestation to verify that the connected server runs inside an authentic Intel® SGX enclave.
There are a few aspects of RA-TLS architecture that were not covered in this white paper. Some of the gaps include the specific X.509 extension OID value for the SGX quote, the supported types of SGX quote, and how the public key is hashed. Additionally, since the white paper was published, new TEEs like Intel® Trust Domain Extensions (Intel® TDX) and new quote formats have become available. The level of specificity in the RA-TLS paper left room for incompatibility between different implementations and prevented their interoperability.
RA-TLS has been supported in multiple open-source projects, including Gramine, RATS-TLS, Open Enclave Attested TLS, and SGX SDK Attested TLS. The CCC Attestation SIG invited these projects to its meetings for review, and recommended further investigation to look into harmonization between them for interoperability. Following up on this recommendation, we conducted an in-depth investigation and identified areas of incompatibility. We documented our findings, created a draft proposal for an interoperable RA-TLS architecture, and presented our work back to the SIG.
Based on the interoperable RA-TLS draft proposal, we refined the design, and aligned it with the upcoming DICE Attestation Architecture v1.1 draft standard on X.509 extension OID value and evidence format definition (as a tagged CBOR byte string). We created an CCC Attestation SIG github project interoperable-ra-tls to host the design documents and interoperability tests. This project also facilitates discussion among members of the RA-TLS projects and the CCC Attestation SIG community in general. In addition, we registered the needed CBOR tags with the IANA registration service. In the process, we provided feedback to the DICE Attestation Architecture workgroup for refinement of their draft standard specification.
Great progress has been made to implement this proposed interoperable RA-TLS scheme in the RA-TLS projects. We’ve worked with all the projects to create issues and pull requests for their implementations. Especially, as discussed in some of the interoperable-ra-tls project issues, Gramine and RATS-TLS have completed their implementation, and have been active in interoperability tests.
In summary, the interoperable RA-TLS work demonstrated the value of the CCC Attestation SIG in providing a constructive forum to collaborate on attestation technology. We invite you to try out the new unified implementations in Gramine and RATS-TLS. If you are interested in getting more involved, please join us at the CCC Attestation SIG or any other facet of our Confidential Computing Consortium open source community. All are welcome here.

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.

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 the 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.
– Dan Middleton, TAC Chair (2023)
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!
– Ravi Sharma, Outreach Chair (2022)
ProjectsPlease find updates from the CCC projects below:
The Confidential Computing Consortium (CCC) was present at the 25th edition of Black Hat USA and the 30th edition of DEF CON.
At Intel’s booth for Black Hat, there was a big effort towards bringing awareness to Confidential Computing, including the distribution of outreach material from the Confidential Computing Consortium, as well as sessions from Anjuna (“Confidential Computing 101”) and Fortanix (“Confidential Computing AI & Intel SGX: accelerating the use of AI/ML”).
One of the highlights of Black Hat was the responsible disclosure of the ÆPIC Leak by researchers Pietro Borrello (Sapienza University of Rome) and Andreas Kogler (Graz University of Technology) and their collaboration with Intel to mitigate the vulnerability. After their session at Black Hat, the researchers and their colleagues met with the Confidential Computing Consortium representatives and shared how they worked closely together with Intel to follow responsible vulnerability disclosure practices. Intel has provided a microcode update for processors with Intel SGX to enable support to clear buffers and mitigate potential exposure of sensitive stale data when exiting Intel SGX enclaves.
At DEF CON, the Confidential Computing Consortium was mostly present at the Crypto and Privacy Village, which provides a forum for the hacker community to share knowledge and discuss cryptography and privacy.
Community members of the Enarx project gave two talks at the Crypto and Privacy Village: “Owned or pwned? No peekin’ or tweakin’!” and “Cryptle: a secure multi-party Wordle clone with Enarx”. The talks were presented by Richard Zak, Tom Dohrman, and Nick Vidal, with assistance from Ben Fischer from Red Hat.
We would like to thank attendees and organizers of Black Hat, DEF CON, the Crypto and Privacy Village, as well as staff and members of the Confidential Computing Consortium, including representatives from Anjuna, Fortanix, Intel, Profian, and Red Hat/IBM.
Please consider the following submission to the Request for Information on Advancing Privacy-Enhancing Technologies from the Confidential Computing Consortium. The Confidential Computing Consortium (https://confidentialcomputing.io) is a Linux Foundation project “to accelerate the adoption of Trusted Execution Environment (TEE) technologies and standards” and has a diverse membership of hardware and software vendors and cloud service providers (https://confidentialcomputing.io/members/). This response was prepared by the group’s Technical Advisory Council with participation from across the membership, and ratified by its Governing Board. The Linux Foundation is a non-profit organization registered in the United States as a 501(c)(6).
The Confidential Computing Consortium has a mandate to engage with governments, standards agencies and regulatory agencies to encourage adoption of Confidential Computing, as well as work with the larger ecosystem and engage with existing and potential end-users of the technologies.

Confidential Computing Consortium, Governing Board Chair
The Confidential Computing Consortium (CCC) was one of the 10 communities selected to be part of Roadsec, LATAM’s largest hacker conference. Over 5000 participants were present at this in-person conference held in Sao Paulo.
Roadsec started as meetups about cyber-security that were organized across different cities (thus the name Roadsec, as speakers were always on the road). Every year the community gathers in Sao Paulo for the main conference.
Sao Paulo is considered an alpha global city and serves as Latin America’s financial and technological hub. Major banks and cloud service providers have their headquarters and data centers in this city.
Nick Vidal, CCC’s Outreach Committee Co-Chair, was at the conference promoting the CCC and also inviting participants to the Cryptle Hack Challenge, a secure multi-player Wordle clone that demonstrates how Confidential Computing works.
Roadsec organizers were kind enough to provide the CCC a booth to present this emerging technology called Confidential Computing, which protects data in use by performing computation in a hardware-based Trusted Execution Environment. These secure and isolated environments prevent unauthorized access or modification of applications and data while in use, thereby increasing the security assurances for organizations that manage sensitive and regulated data.
Recently, there have been many serious cyber attacks in Brazil, including the leakage of sensitive patient data from DATASUS and sensitive client data from Banco Pan. Confidential Computing could have helped prevent these data leakages.
The Confidential Computing Consortium is thrilled to welcome the Veraison project. Project Veraison builds software components that can be used to build an Attestation Verification Service. Learn more at https://github.com/veraison.
