CCC Newsletter – January 2023

By Newsletter No Comments

Welcome to the January 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. This newsletter is also available on our website.

Introduction

The start of the new year is the perfect opportunity to reflect about the year that has passed and what we have accomplished collectively in 2022. It has been a pivotal year for the CCC in many regards. Please check the updates from the Technical Advisory Committee, the Outreach Committee, the CCC projects, and the Special Interest Groups.

New Members

Cape Privacy and Canonical joined the Confidential Computing Consortium.

Cape Privacy is a confidential computing platform to easily run serverless functions on encrypted data. Cape empowers developers to build secure applications which protect the underlying data and code from the cloud.

Canonical is committed to enabling Ubuntu users to leverage the strong run-time confidentiality and integrity guarantees that confidential computing provides. The mission of the Confidential Computing Consortium of driving cross-industry open source software, standards and tools greatly resonates with us and we are really excited to have joined its members.

Upcoming Events

FOSDEM

The Confidential Computing Consortium will be participating at the Confidential Computing devroom at FOSDEM. A social event is being sponsored by the CCC on the 4th of February.

State of Open Con

The Confidential Computing Consortium will have a table at the State of Open Con, a conference being organized by OpenUK in London on the 7-8th of February.

CCC Webinar: Confidential Computing in Financial Services

The next CCC webinar will happen on February 16 at 8:00 am PT. Featured speakers include Bessie Chu (Cape Privacy), Gavin Uhma (Cape Privacy), Mark F. Novak (JP Morgan Chase), and Richard Searle (Fortanix).

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.

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!

CCC at Black Hat and DEF CON 2022

By Blog, CCC Events No Comments

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.

Roadsec: LATAM’s largest hacker conference

By Blog No Comments

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.

CCC Project Updates

Gramine

Gramine project (formerly known as Graphene) will release a new stable version v1.2 in upcoming weeks.

Gramine is a library OS that enables protecting sensitive workloads with Intel® Software Guard Extensions (Intel® SGX). Gramine runs unmodified Linux applications on Intel® SGX out of the box and provides all functionality required for end-to-end protection of workloads: remote SGX attestation, transparent encryption of security-critical files, secure multi-processing. Gramine follows a “lift-and-shift” paradigm for running unmodified applications: to “graminize” the application, it is enough to write a so-called *manifest* file that reflects a runtime configuration of the protected application. Gramine also supports Docker integration via a tool called Gramine Shielded Containers (GSC) and provides a growing set of curated applications, runtimes and frameworks.

In comparison to the previous release, Gramine v1.2 introduces a major overhaul of the FS subsystem. In particular, the Protected Files (PF) feature was significantly reworked. A new manifest syntax allows to mark whole FS mounts for encryption. The PF feature is now available not only in the SGX mode of Gramine, but also in the direct mode, for ease of debugging. We also added support for renaming PFs, memory mapping them with read-write permissions and encrypting them with different user-supplied encryption keys. As a side effect of this rework, multiple bugs in the FS and PF subsystems were fixed.

Additionally, Gramine v1.2 introduces a final reworked CPU/NUMA topology feature (previously marked as experimental). Now, CPU/NUMA topology is securely forwarded inside a Gramine SGX enclave and enabled by default. Among other improvements in Gramine, we highlight better support for CentOS/Fedora/RHEL Linux distributions and the update of the EPID SGX attestation tools to use IAS API v4. We also added a Rust example (a simple web server that uses hyper and tokio crates), as well as a new Python example for SGX quote retrieval.

Along with this technical work, Gramine was presented in different forums and featured in articles and blog posts:

– Gramine talk at the FOSDEM’22 conference: https://fosdem.org/2022/schedule/event/tee_gramine/

– Enarx 0.4.0 (Fort of Dhat al-Hajj) released in April with SGX2 support, improved TLS support, and much more (https://blog.enarx.dev/enarx-0-4-0-fort-dhat-al-hajj/).

– Enarx 0.5.0 (Elmina Castle) released in May with many new/improved features: New enarx deploy subcommand. SGX with EDMM / SGX2 support (https://blog.enarx.dev/elmina-castle/).

In addition to Linux, Enarx is now available on MacOs, Windows, and Raspberry Pi:

– Enarx can now be compiled on additional platforms in a light development version. From MacOS to Raspberry Pi — Extending the Enarx Development Platforms.  (https://blog.enarx.dev/backend-nil/)

The Enarx project announced the Cryptle Hack Challenge:

– Cryptle is a secure multi-player clone of Wordle. The goal of the Cryptle Hack Challenge is to uncover vulnerabilities in the Enarx project. (https://blog.enarx.dev/cryptle-hack-challenge/).

The Enarx community has achieved a huge milestone: we have collectively published 100 tutorials and articles over at Wasm Builders!

– As part of the Confidential Computing Fellowship program, the Enarx project has received several mentees from Outreachy and LFX Mentorship. Wasm Builders has served as a welcoming environment where Enarx community members can share their learning experiences with others (https://blog.enarx.dev/enarx-community-reachs-100-tutorials/).

The Enarx project has participated in the following events:

– Nathaniel McCallum presented “WASI Networking” at Wasm Day at KubeCon + CloudNativeCon Europe 2022 (https://blog.profian.com/wasm-day-at-kubecon-cloudnativecon-europe-2022/).

– Outreachy intern Shraddha Inamdar presented “Enarx: The Platform Abstraction for Trusted Execution Environments” at FOSSASIA (https://enarx.dev/resources/2022-04-09-fossasia).

– CCC Fireside Chat: Stephen Walli received Mike Bursell to discuss his book “Trust in Computer Systems and the Cloud,” with a particular focus on the impact of Confidential Computing on security, trust and risk (https://blog.profian.com/trust-in-computer-systems-and-the-cloud/).

Veracruz

  • We recently announced our 22.05 release which included first-time contributions from several people including Aryan Godara, Mohamed Abdelfatah, and Sagar Arya.  Many of these contributions focussed on adding new examples to the Veracruz repository.  Mohamed will be joining us as our Outreachy-sponsored intern shortly, working on providing better documentation of the expected behavior of Wasi system calls (https://github.com/veracruz-project/veracruz/releases/tag/veracruz-2205).
  • We’ve worked to simplify Veracruz attestation further, across all of our supported platforms, making the process more uniform and removing platform-specific quirks.
  • We’ve started work, and are progressing quickly, on supporting seL4 as an in-enclave operating system for ultra-low TCB enclaves.
  • We’ve worked to improve Veracruz documentation.
  • Many other smaller bug fixes, performance improvements, and upgrades of dependencies to fix security concerns.

The CCC welcomes 5 new General Members and Gramine project during final quarter of 2021

By Announcement No Comments

The Confidential Computing Consortium is thrilled to welcome five new General Members and the Gramine project. The community continues to grow with a total of 36 corporate members, 4 nonprofits, and 6 projects.

New General Members include:

Baidu USA

Canary Bit

HUB Security

Opaque Systems Inc

Technology Innovation Institute

The Gramine project will be hosting a webinar on February 3, 2022 at 9am PST. You can register here.

More on Gramine project:

Following the first production-ready release “v1.0”, The Gramine Project is releasing “v1.1” in upcoming weeks. One highlight of this release is stability improvements for Golang and Rust workloads. Another prominent feature of the release is support for the musl C standard library – now Gramine allows users to choose between glibc and musl, depending on users’ requirements on the binary size (TCB), as musl is more light-weight than glibc. Also, AddressSanitizer was integrated in Gramine, and it runs in the CI on each change, for detecting any security issues ahead of code merge. This version adds several other features as well as multiple bug fixes (thanks to our ever-increasing user base for reporting issues!).

While there are several use cases under development, we would like to highlight the production release of the OpenVino Security Add-on (OVSA) for Model IP protection (consider using it for your protected ML workloads). Please reach out to the Gramine team if you are experimenting with Gramine and would like to be added to the list of “Users of Gramine

Enarx

In Enarx’s first release “version .0.1.0” (codenamed Alamo) we provided WebAssembly as a runtime. For our upcoming release “version 0.2.0” this coming quarter we are looking forward to providing support for attestation, including Intel’s SGX and AMD’s SEV.

Other areas where we are working on are support for filesystem and networking, which depend on upstream collaboration with the WebAssembly community.

Enarx is under high development and is not production ready yet, but our hope is that these initial releases will allow developers to experiment with Enarx and see its progress.
