Open More and Trust Less in Binary Verification Service -- Towards a Trusted App Store for Confidential Computing

Hongbo Chen

Hongbo Chen

Research Assistant

Indiana University

In the contemporary landscape of AI and big data analytics, ensuring the secure and private exchange of data is crucial. Yet, safeguarding data-in-use presents a substantial challenge, underscoring the need for innovative solutions. The National Science Foundation's Center for Distributed Confidential Computing (CDCC) is at the forefront of addressing this issue, pioneering research to lay down the technical groundwork for scalable data protection across cloud and edge computing environments. This talk aims to introduce CDCC—a multifaceted initiative supported by the National Science Foundation—highlighting its multidisciplinary approach and multi-institutional collaboration. We will delve into the center's principal research avenues, such as the verification of Trusted Execution Environment (TEE) code, the integrity of computing nodes, the coherence of workflows, and the alignment with stakeholder expectations. These efforts converge to forge a resilient ecosystem for confidential computing, characterized by open certification for TEE code, adaptable policy models for data use, extensible data control at runtime, and rigorous adherence to data-use policies across workflows. Moreover, this presentation will showcase the practical impacts of these endeavors, particularly through the lens of enabling secure applications like confidential disease prognosis.  A focal point of our discussion will be the development of a Trusted Application Store (TAPStore), beginning with the foundational step of creating a verifier tailored for TEE binaries. This initiative has led to the design of an innovative verification service that balances openness with trustworthiness. At the heart of this approach lies a strategic insight: certain tasks can be delegated to untrusted entities, while the corresponding validators are securely housed within the trusted computing base (TCB). The service can validate untrusted proof generated for versatile policies. Through a novel blockchain-based bounty task manager, it also utilizes crowdsourcing to remove trust in theorem provers. These synergistic techniques successfully ameliorate the TCB size burden associated with two procedures: binary analysis and theorem proving. Therefore, it allows untrusted parties to participate in these complex processes. Moreover, based on running the optimized TCB within trusted execution environments and recording the verification process on a blockchain, the public can audit the correctness of verification results. We also implement verification workflows for software-based fault isolation policy and side-channel mitigation to demonstrate its efficacy.  Through this exploration, attendees will gain insight into the cutting-edge research and developments emerging from the CDCC.

EscrowAI - A Confidential Computing Based ML Lifecycle Collaboration Platform

Alan Czeszynski

Alan Czeszynski

Vice President, Product

BeeKeeperAI, Inc.

EscrowAI is a patent-protected, privacy-enhancing ML/AI lifecycle collaboration platform enabling secure collaborations between algorithm developers and stewards of protected data. EscrowAI automates the use of Trusted Execution Environments (TEE) using confidential computing, along with other privacy-enhancing technologies, to ensure data sovereignty, security, and individual privacy, and to protect the algorithm's intellectual property throughout the ML lifecycle. The entire computing workflow in the TEE is fully automated, democratizing confidential computing for everyday data science tasks (training, test, validation, federation) across all industries that rely on protected data and IP security. EscrowAI enables data to remain within the data steward's secure environment where it is made available for computation in a hardware-based TEE instance. Encrypted algorithms are brought into the TEE, and the algorithms and data are decrypted in the TEE instance's protected memory with user-created private keys stored in an HSM key vault. The computation is executed, and only a predetermined output is allowed out of the TEE instance after verification by EscrowAI. After the computation is complete, the TEE instance is decommissioned. A variety of confidential computing resources are available, including application enclaves, confidential containers, and confidential virtual machines. A confidential ledger is used to create immutable records of AI/ML artifacts from computing cycles to create trustworthy AI. As an example. BeeKeeperAI is working with the US Novartis Foundation's Beacon of Hope initiative, along with the leading Historically Black Colleges and Universities (HBCU) medical schools, to use EscrowAI to investigate racial bias in clinical algorithms. These data stewards have rich data sets, including social determinants of health, that cannot be de-identified or otherwise obscured. EscrowAI enables HBCU medical schools to participate in AI/ML innovation using these data sets from typically under-represented populations. This critical research hopes to help resolve the lack of access to diverse data when training and validating algorithms for use within the clinical environment, which was identified as a critical shortcoming by the US Department of Health and Human Services' Office of Minority Health. EscrowAI is available in the Azure Marketplace.

Principal MTS, Security Architecture

Rivos Inc.

Multi-tenant computing platforms are typically composed of several software and hardware components including programmable logic, platform firmware, operating systems, virtualization monitors, and tenant workloads (typically operating in a virtual machine, container, or application context). In this complex TCB environment, Confidential Computing is gaining traction in large scale commercial deployments, with the majority of hyper-scalers adopting this computing model. As computing becomes increasingly heterogeneous with a mix of general purpose, fixed function and accelerator engines - new platform components, operators and software frameworks have to be reasoned about to manage the impact on the Trusted Computing Base (TCB) for workloads. Confidential computing with its strong requirements around HW-backed attestation presents a good stepping-stone towards providing a quantifiable TCB for such a complex computing model. The RISC-V architecture especially presents a strong foundation for meeting the requirements of both Heterogenous Computing and Confidential Computing in a clean slate manner with an open ISA. This session describes the reference architecture and discusses RISC-V ISA, non-ISA (SW/HW) and system-on-chip (SoC) infrastructure capabilities that are currently in definition as part of the Confidential Virtual-machine Extension for RISC-V (referred to as CoVE). The session also covers common standards that RISC-V CoVE enables and supports to provide interoperability across RISC-V and non-RISC-V implementations. The goals of this session are to share status and ideas with the confidential computing community, to get feedback on the ISA and non-ISA specifications in development, and identify common building blocks projects that can enhance the open source development and deliverables of the RISC-V task groups working on confidential computing.

Confidential AI and Intel Trust Authority

Raghuram Yeluri

Raghuram Yeluri

Senior Principal Engineer, Lead Security Architect

Intel Corporation

Attestation is the ground truth of Confidential AI. As a model owner and data owner, you want very precise clarity on the integrity and confidential of the infrastructure, the workloads, and the environment in which the models and data are accessed and operated on. Attestation provides that clarity and definitive proof. This proof of attestation has to be acquired in a very simple, and straightforward way, with near zero changes to your applications/workloads and workflows. This is where Intel Trust Authority comes in (ITA). ITA has a singular goal: Make attestation boring and a non-event, so data scientists, data owners can focus on what is important for them, with the assurance that their models and data are protected. In this session we will share how ITA simplifies getting attestation of the CPU TEEs and/or the attached GPU TEEs, with 1 (that is right!) call to the ITA Client CLI. The ITA Client will manage the details of communicating with TEE hardware (both CPUs and GPUs) for evidence, transmitting the evidence to the ITA Service, and respond with a signed composite attestation token. The application can use this token to make decisions from here. ex: provide the token as proof to a Relying Party to get some secrets, decide to accelerate training using a trusted GPU, etc. You will learn the details about ITA, the ITA Client (SDK), and how to use with Intel TDX and NVidia H100 TEEs. There will also be a discussion of the Intel Trust Authority roadmap, to provide the audience a view of what to expect the rest of 2024.

Gramine-TDX: A Lightweight OS Kernel for Confidential Virtual Machines

Dmitrii Kuvaiskii

Dmitrii Kuvaiskii

Research Scientist

Intel Labs

Confidential Virtual Machines (CVMs) have emerged to protect data in use by performing computations in hardware-based Trusted Execution Environments (TEEs). Typically, a legacy feature-rich VM is re-packed into an encrypted CVM, such that the entire VM is protected from privileged insider attackers, running cloud-native workloads in a secure and isolated fashion. However, this primary usage of CVMs is not suitable for small, specialized, security-critical workloads: legacy VMs with their conventional OS distributions and a plethora of applications, tools, and files result in unnecessarily bloated CVMs that expose a large set of attack vectors. Moreover, CVMs are commonly based on the Linux kernel that was never intended for Confidential Computing (CC) and thus does not protect against certain attack vectors. We propose the Gramine-TDX OS kernel to execute slim, single-purpose, security-first unmodified Linux workloads with a minimal attack surface, using Intel TDX. We base our work on Gramine-SGX, a battle-tested TEE runtime tailored for CC usages. This allows us to build on the existing protections of Gramine-SGX and focus only on the CVM-specific attack surface.

Founders

Enkrypt AI

Tanay Baswa, Pradipta Banerjee, Sahil Agarwal, Prashanth Harshangi Machine Learning (ML) providers are increasingly concerned with protecting their intellectual property (IP) and the confidentiality of their model weights. This concern naturally gravitates towards a cloud-based ML as a Service (MLaaS) solution. Concurrently, there is a significant demand from enterprises to leverage these ML services without compromising their confidential data to external infrastructures or untrusted parties. A growing number of customers are insisting on deploying ML services on-premises to maintain control over data flow. This scenario presents an opportunity to employ confidential computing solutions, utilizing the Confidential Containers (CoCo) project to securely deliver ML models and services directly to customers' premises. Such an approach ensures the protection of the ML provider's IP and model integrity while enabling customers to run ML services within their infrastructure securely. By encrypting data sent to the ML service using asymmetric cryptography, customers are assured that their sensitive information is only decrypted in a secure environment, invisible even to themselves while it is in use. Key Insights and Technologies: Confidential Containers: At the forefront of this solution, the CoCo project serves as the pivotal technology for securely delivering ML models. Using CoCo methods allows us create a trusted execution environment on the customer's premises to run encrypted ML containers, effectively safeguarding the model's IP alongside the customer's data. Workload Container Encryption: We allow ML providers to encrypt their containers using the CoCo key-provider. This encrypted workload can only be decrypted inside a TEE by a corresponding CoCo Key Broker Service. This simplifies the storage and delivery process for ML providers by guaranteeing that their workload will only be decrypted and executed within an attested and confidential environment, thereby guaranteeing the protection of their IP. Simplified Deployment Process: The deployment of confidential containers is made accessible through streamlined scripts. This ease of deployment ensures that both ML providers and customers can effortlessly set up the confidential computing environment, facilitating the secure execution of ML workloads without requiring extensive technical expertise. Seamless Deployment with End-to-End Privacy: Our solution offers a streamlined deployment process that handles all aspects of remote attestation and verification automatically. Additionally, by hosting a verifier container that also facilitates the encryption of data entering and leaving the TEE, we can ensure end-to-end privacy. Key Takeaways: Protecting IP and Data: The use of confidential containers and encryption technologies ensures that ML models are securely delivered and executed, protecting both the provider's IP and the customer's data. Secure Deployment on Customer Premises: This solution enables the secure deployment of ML services on customers' premises, addressing concerns about data privacy and control over data flow. Ease of Use: The streamlined process for encryption and deployment, facilitated by scripts and comprehensive guidelines, makes it easier for both providers and customers to implement confidential computing solutions. Enhanced Security with Encryption and Isolation: The combination of encrypted memory execution and isolated runtime environments significantly boosts the security of executing ML workloads, minimizing the risks associated with data leaks or unauthorized access. Conclusion For ML providers wanting to distribute their models without compromising on IP safety and data privacy, our approach offers a seamless and efficient solution. For customers, it provides a way to utilize advanced ML services while maintaining control over their confidential data, ensuring that both insights and integrity are preserved. The deployment of confidential encrypted containers represents a forward-thinking solution to the challenges of data privacy and IP protection in the cloud-based MLaaS landscape.

Klave also provides unparalleled auditability, enabling you to ensure the integrity of your data and code and maintain unassailable records for audits and adherence to regulations. This is achieved by combining Confidential Computing and Distributed Ledger Technology (DLT). Confidential Computing ensures that data remains protected even while in use, protecting data and code at their most vulnerable. This helps organisations to control the exposure of their data to third parties and to demonstrate transparency regarding data management, usage, and protection. The DLT ensures data integrity and auditability, streamlining the process of evidence generation and gathering to comply with regulations, detect threats or mitigate legal challenges. Klave utilises hardware-based secure enclaves to create trusted execution environments where sensitive data remains encrypted and isolated from both Klave and the underlying system. This protects against unauthorised access and mitigates the risk of insider threats and malicious attacks. Inside these enclaves, a Zero-Trust runtime uses certificate cryptography mechanisms to continuously verify the identity of every platform component, application, user and device, reducing the risk of unauthorised access and insider threats. Memory sandboxing techniques are in place to create isolated WebAssembly execution contexts, ensuring that access to data is strictly controlled during execution. Additionally, by anchoring every applicative transaction deterministically onto a distributed ledger, Klave ensures integrity and immutability of both data and process, thus enhancing trust and accountability in a code-is-law fashion while defending against destructive attacks such as ransomware. Klave empowers organisations to unlock their data's full potential in several ways, including securely deriving insights, facilitating sensitive data collaboration and collective intelligence, helping with evidence gathering for compliance and conformity, and bolstering internal and external threat protection measures.

GuaranTEE: Towards Attestable and private ML with CCA

Sandra Siby

Sandra Siby

Research Associate

Imperial College London

Machine-learning (ML) models are increasingly being deployed on edge devices to provide a variety of services. However, their deployment is accompanied by challenges in model privacy and auditability. Model providers want to ensure that (i) their proprietary models are not exposed to third parties; and (ii) be able to get attestations that their genuine models are operating on edge devices in accordance with the service agreement with the user. Existing measures to address these challenges have been hindered by issues such as high overheads and limited capability (processing/secure memory) on edge devices. In this work, we propose GuaranTEE, a framework to provide attestable private machine learning on the edge. GuaranTEE uses Confidential Computing Architecture (CCA), Arm's latest architectural extension that allows for the creation and deployment of dynamic Trusted Execution Environments (TEEs) within which models can be executed. We evaluate CCA's feasibility to deploy ML models by developing, evaluating, and openly releasing a prototype. We also suggest improvements to CCA to facilitate its use in protecting the entire ML deployment pipeline on edge devices.

Marc Meunier

Director of Ecosystem Development

Arm

Confidential computing protecting data in use is a hot topic within the
semiconductor industry at large. Hardware-based enclaves such as AMD SEV, Intel SGX/TDX, and Arm CCA are now considered the most pragmatic approach to this. So far, the focus has been given to implementing confidential computing into CPUs. Without extending confidential computing to other classes of devices, how could an AI business outsource the training of its models to a remote cloud platform complex systems combining AI accelerators, storage devices, network interfaces, etc., and have the strong guarantee that its data is protected from both the platform and other customers sharing the same resources? This limitation is detrimental to the wider adoption of confidential computing, particularly in the datacenter.

We present a case study of confidential computing extended to Data
Processing Units (DPUs), a device optimized for high-throughput I/O and
used by hyperscalers to offload tasks such as TCP/TLS, over-the-network
storage operations and asymmetric cryptography. We will go through what
makes the intersection of confidential computing and DPUs so interesting,
and will present our ongoing work exploring new use cases such as vicarious attestation and confidential TLS offload. Technologies discussed during the talk: Confidential VMs, DPUs, TLS, Virtual Private Cloud, remote

Enterprises preferably deploy a 3-2-1 backup strategy when they deploy enterprise data protection platforms (e.g., Cohesity) for backup and off-site copy. Security-sensitive customers mitigate data privacy issues by deploying data protection appliances (e.g., Cohesity) in an isolated and customer-controlled environment. For off-site copy, they trust data protection service providers for data privacy. Customers are increasingly challenging these trust assumptions and demanding private off-site storage solutions. To meet these emerging demands, we propose using confidential computing (e.g. Intel SGX) to guarantee off-site storage privacy. In this session, we present how confidential computing primitives help achieve data privacy guarantees even if an attacker compromises the off-site storage solution providers.

The identity & credentials economy has been relatively stable for a very long period. .For hundreds of years, it has been a quasi institutional monopoly centered around governments and universities, and with relatively little change and innovation. But recently, this industry has begun to be disrupted by the globalization of higher education and labor markets, requiring credentials to work over a much larger scale. The increasing need for access to digital services, which require multiple forms of digital identity, for digital wallets, online banking, social media accounts, etc. carries significant risk, if not thoughtfully designed and carefully implemented. A new form of identity is needed, one that weaves together technologies and standards to deliver key identity attributes, such as self-ownership and censorship resistance, that are difficult to achieve with existing systems. Cryptographically secure, decentralized identity systems could provide greater privacy protection for users, while also allowing for portability and verifiability. This session describes an architecture reference for Decentralized Identities (DIDs) that fits in the self-sovereign identity (SSI) framework of issuer - holder - verifier process. The solution architecture demonstrates how to make this "trust triangle" trustworthy and confidential. Confidential Identity Hubs, hosted on confidential computing infrastructure in multiple "hubs" around the world create the necessary distributed network for storing and securing identity elements at scale. Security of sensitive data is ensured by the redundancy of the distributed network, and governance remains decentralized by removing sole ownership of the provided infrastructure.
