The rapid adoption of AI and data-driven technologies has revolutionized industries, but it has also exposed a critical tension: the need to balance robust security with explainability. Traditionally, these two priorities have been at odds. High-security systems often operate in opaque “black box” environments, while efforts to make AI systems transparent can expose vulnerabilities. 

Verified Computing bridges this gap that reconciles these conflicting needs. It enables organizations to achieve unparalleled data security while maintaining the transparency and accountability required for compliance and trust.

The Core Technologies That Make It Possible

1. Trusted Execution Environments (TEEs)

TEEs are hardware-based secure enclaves that isolate sensitive computations from the rest of the system. They protect data and processes even if the operating system or hypervisor is compromised. Examples include Intel® SGX, Intel® TDX and AMD SEV.

• How They Work: TEEs operate as secure zones within a processor, where data and code are encrypted and inaccessible to external actors. For example, during a financial transaction, a TEE ensures that sensitive computations like risk assessments are performed without exposure to the broader system.
• Why They Matter: They protect data “in use,” closing a crucial gap in the data lifecycle that encryption alone cannot address.

2. Remote Attestation

Remote attestation provides cryptographic proof that a TEE is genuine and operating as expected. This ensures trust in the environment, particularly in cloud or collaborative settings.

• How It Works: A TEE generates an attestation report, including a cryptographic signature tied to the hardware. This report confirms the integrity of the software and hardware running within the enclave (source).
• Why It Matters: Remote attestation reassures stakeholders that computations occur in a secure and uncompromised environment, a critical requirement in multi-tenant cloud infrastructures.

3. Confidential Virtual Machines (VMs)

Confidential VMs extend TEE principles to virtualized environments, making secure computing scalable for complex workloads. Technologies like Intel® TDX allow organizations to isolate entire virtual machines.

• How They Work: Confidential VMs use memory encryption to ensure that data remains secure during processing. Encryption keys are hardware-managed, inaccessible to the hypervisor or OS (source).
• Why They Matter: They enable secure data processing in public clouds, even in shared infrastructures.

4. Verified Compute Frameworks

Verified Compute frameworks build on TEEs by introducing mechanisms for generating immutable logs and cryptographic proofs of computations. An example is EQTY Lab’s Verifiable Compute.

• How They Work: These frameworks capture the details of computations (inputs, outputs, and environment integrity) in tamper-proof logs. These logs are cryptographically verifiable, ensuring transparency without compromising confidentiality.
• Why They Matter: They allow organizations to meet regulatory requirements and provide explainable AI outputs while safeguarding proprietary algorithms and sensitive data.

5. Homomorphic Encryption and Secure Multi-Party Computation (SMPC)

In cases where external collaboration or ultra-sensitive data handling is needed, additional cryptographic techniques enhance confidentiality.

• Homomorphic Encryption: Enables computations on encrypted data without decryption.
• SMPC: Distributes computations across multiple parties, ensuring that no single party has access to the complete dataset.
• Why They Matter: These techniques complement TEEs by enabling secure collaboration across untrusted parties.

How Verified Computing Bridges Security and Explainability

Achieving Transparency Without Sacrificing Security

Traditionally, efforts to make AI systems explainable required exposing internal processes or sharing sensitive data—practices that risked data breaches or model theft. Verified confidential computing changes the game by:

• Allowing computations to occur in TEEs or confidential VMs, ensuring data is secure at all times.
• Using verified compute frameworks to provide cryptographic evidence of computation integrity, allowing external parties to trust results without accessing sensitive details.

For example, a healthcare provider running an AI diagnostic tool can securely process patient data in a TEE. The AI’s decisions can be explained to regulators or patients using cryptographic proofs, without exposing proprietary algorithms or patient information.

Supporting Regulatory Compliance

Regulations like the General Data Protection Regulation (GDPR) and the Health Insurance Portability and Accountability Act (HIPAA) demand both robust security and transparent handling of sensitive data. Verified confidential computing offers a solution by generating immutable logs and proofs that demonstrate compliance. This reduces audit complexity and ensures adherence to privacy laws.

Building Trust in AI Systems

As AI plays a growing role in critical sectors, trust is paramount. Verified computing ensures that stakeholders can verify:

1. The Security of the Data: Through TEEs and confidential VMs.
2. The Integrity of Computations: Via cryptographic attestation and verifiable compute frameworks.
3. The Explainability of Results: Through transparent logging and auditable records.

For instance, financial institutions can use verified computing to process loan applications, providing regulators with evidence of fairness and transparency without compromising customer data security.

Verified Compute

Verified Computing is more than a technological advancement—it is a paradigm shift. By integrating technologies like TEEs, remote attestation, confidential VMs, and verifiable compute frameworks, it resolves the long-standing tension between security and explainability. Organizations can now protect sensitive data, ensure compliance, and provide transparent, trustworthy AI systems.

As industries adopt this approach, verified computing will become the gold standard for secure and accountable digital transformation. Bridging these historically conflicting priorities paves the way for a future where trust in AI is not just an aspiration, but a guarantee.

Mike Bursell (Executive Director, Confidential Computing Consortium):

Open Source as the Foundation of Trust:

Mike emphasizes that “Magic pixie dust to all of these is open source because you need to know that the software which is guaranteed seeing all of this stuff has been correctly written and there are no people trying to exfiltrate your data or do evil stuff with these keys as you go along…….. without that you just don’t get the scale taking off, that’s really important.“

Simplifying Complex Technologies:

Mike also highlights the importance of abstracting complex technologies like TEEs to make them accessible to users without deep technical expertise. “That’s exactly what companies like Super Protocol are doing and the sort of thing that we are encouraging in the Confidential Computing Consortium as well. So, reducing the friction, bringing it to users who don’t need to know the really low-level detail- it does get very, very techy very, very quickly…“

Nukri Basharuli (Founder and CEO, Super Protocol):

Effective Collaboration Among Companies:

Nukri Basharuli points out “the last McKinsey report says 90% of large and medium companies want to collaborate based on their data. But at the same time, there are two opposite vectors: on one side, you need to collaborate on data with your partners, even with your direct competitors – to observe the market, to find insights, and to grow. But at the same time, you need to prevent these leakages and risks of cannibalization of each other. That’s why verifiable and confidential computing gives us opportunities to make this collaboration effective and provable.”

Accessibility of TEEs:

Nuri discusses Super Protocol’s development of a “ready-made AI & Data Marketplace within a confidential cloud based on TEE. “In just a few clicks, you will be able to launch your model, upload your model from our Marketplace or from Hugging Face, in a fully private decentralized environment. Just a few clicks – deploy a smart contract and… this is why we are building Super: to make this road as easy as possible for millions of projects developing billions of personal AI agents based on personal data for businesses, private needs, and so on…….And you can make this connection verifiable for all participants – that’s why this is a big difference and next is that everything behind smart contracts in Super is governed only by smart contracts – all services, all computation services, 100% of services are governed only by smart contracts. This is another difference from a centralized cloud which is governed by an administrator or owner of the service.”

David Attermann (Head of Web3 Investments, M31 Capital):

Growth of the Confidential Computing Market:

David Attermann predicts: “The confidential computing market is expected to grow 50% annually for the next 10 years. The demand for it is real, and it’s becoming a major industry now. Within Web3, TEEs have gained momentum as the most practical way to verify compute. For the next five years, TEEs will likely serve as the foundation for all verifiable compute in Web3.

Unique Capabilities of Super Protocol: 

David also notes that “even without an interest in cryptocurrencies, one can appreciate the unique functionalities offered by Super Protocol.“

What if you could collaborate on AI projects, run complex models, fine-tune them, and even monetize both your models and data – all while retaining full control and ensuring confidentiality? It might sound impossible, especially when involving multiple participants you don’t need to trust – or even know.

In his article, “Web3 plus Confidential Computing,” Mike Bursell, Executive Director of the Confidential Computing Consortium,  delves into this challenge: “It turns out that allowing the creation of trust relationships between mutually un-trusting parties is extremely complex, but one way that this can be done is what we will now address.“

Mike explores the synergy of Confidential Computing, blockchain, and smart contracts, showcasing Super Protocol as a real-world implementation of this vision. He explains: “Central to Super Protocol’s approach are two aspects: that it is open source, and that remote attestation is required to allow the client to have sufficient assurance of the system’s security. Smart contracts – themselves open source – enable resources from various actors to be combined into an offer placed on the blockchain, ready for execution by anyone with access and sufficient resources. What makes this approach Web3 is that none of these actors needs to be connected contractually.”

This approach enables “the network effect… building huge numbers of interconnected Web3 agents and applications, operating with the benefits of integrity and confidentiality offered by Confidential Computing, and backed up by remote attestation.“ Unlike Web2 ecosystems, often criticized for “their fragility and lack of flexibility (not to mention the problems of securing them in the first place),” here is an opportunity to create “complex, flexible, and robust ecosystems where decentralized agents and applications can collaborate, with privacy controls designed in and clearly defined security assurances and policies.“

As Mike aptly puts it: “Technologies, when combined, sometimes yield fascinating – and commercially exciting – results.“

Introduction:

As enterprises increasingly adopt multi-cloud architectures, managing data governance across distributed systems has become more complex. With data privacy regulations like GDPR and CCPA requiring organizations to maintain strict control over sensitive information, ensuring compliance while leveraging the flexibility of multi-cloud systems presents a significant challenge.

Enter Confidential Computing: by using trusted execution environments (TEEs) and remote attestation across cloud platforms, organizations can ensure that sensitive data is processed in a secure and compliant manner. This blog will explore how decentralized data governance can be achieved in multi-cloud environments using confidential computing technologies.

Why Is Confidential Computing Essential for Multi-Cloud Data Security?

In a multi-cloud setup, organizations often distribute workloads across multiple cloud providers to meet their operational needs. However, this also increases the potential attack surface, as data flows through various infrastructures. Ensuring that data remains secure and compliant with regulations across these disparate environments is critical.

Confidential computing provides a solution by ensuring that sensitive data is processed in secure enclaves within TEEs, which isolate the data from unauthorized access. Using remote attestation, these TEEs can be verified, ensuring that the code executing within the enclave is trustworthy.

This ability to isolate and verify processing environments makes confidential computing essential for ensuring data security and governance across multi-cloud deployments.

What Is Decentralized Data Governance and Why Does It Matter in the Cloud?

Decentralized data governance refers to the practice of managing data policies, access controls, and compliance requirements across multiple locations or platforms without relying on a single centralized authority. In a multi-cloud environment, this is particularly challenging, as each cloud provider may have different security standards, policies, and regulatory requirements.

By decentralizing data governance, organizations can ensure that each cloud provider adheres to specific security and compliance rules. Confidential computing enables this by allowing organizations to enforce strict access controls and data policies at the TEE level, ensuring that data governance is maintained consistently, regardless of where the data is processed.

This approach to governance is crucial for businesses that need to operate in multiple jurisdictions or across cloud infrastructures, ensuring that they meet all relevant regulatory requirements.

How Open Enclave SDK Powers Secure Data Governance in Multi-Cloud Environments

One of the key tools that enables secure data governance in a multi-cloud environment is the Open Enclave SDK. Developed under the Confidential Computing Consortium, the Open Enclave SDK provides a consistent abstraction for creating TEEs across different platforms, including Azure, AWS, and Google Cloud.

By using the Open Enclave SDK, developers can build applications that securely process data in TEEs across multiple cloud environments without having to rewrite code for each cloud provider. This ensures that data remains secure and compliant with governance policies, regardless of the cloud infrastructure being used.

Additionally, the Open Enclave SDK supports remote attestation, allowing organizations to verify that data is being processed in trusted environments across all cloud platforms.

How Remote Attestation Ensures Compliance Across Multi-Cloud Systems

As organizations move workloads across different cloud providers, ensuring that each platform complies with relevant data privacy laws is a key concern. Remote attestation provides a mechanism to verify the security and integrity of TEEs, ensuring that sensitive data is processed only within approved environments.

In the context of GDPR, for example, remote attestation can help ensure that personal data is processed only within TEEs that meet the necessary security and privacy requirements. This ability to verify compliance on the fly allows businesses to confidently use multi-cloud infrastructures while maintaining adherence to data protection regulations.

Remote attestation helps organizations remain agile in the cloud while still upholding strict data sovereignty requirements, ensuring compliance with the CCPA, GDPR, and other global regulations.

Case Study: Confidential Computing in Real-World Data Sovereignty Challenges

A real-world example of decentralized data governance using confidential computing is the case of Italy’s Sovereign Private Cloud initiative. Italy’s government aimed to ensure that critical public sector workloads were processed within secure and private environments, adhering to the country’s strict data sovereignty laws.

By adopting confidential computing and remote attestation, Italy’s sovereign cloud enabled secure processing of sensitive public data across distributed environments. This approach ensured that even when data was processed outside of government infrastructure, it was handled securely in trusted execution environments, and compliance with Italian data protection laws was maintained.

To dive deeper into this solution, you can watch the session titled Sovereign Private Cloud: A Confidential Computing Solution for the Italian Public Administration from the Confidential Computing Summit 2024, where the implementation of the Sovereign Cloud is discussed in detail. The recording is available here.

This use case highlights how confidential computing can help address data sovereignty concerns, enabling organizations to operate securely across multiple cloud infrastructures without compromising compliance.

Achieving Decentralized Data Governance with Confidential Computing

As organizations continue to embrace multi-cloud strategies, managing data governance across distributed environments becomes more complex. Confidential computing offers a powerful solution by securing data in trusted execution environments and enabling remote attestation to verify compliance.

By leveraging tools like the Open Enclave SDK, businesses can maintain control over their data policies and ensure that sensitive information is processed in secure, compliant environments across all cloud platforms. As data sovereignty concerns grow, particularly in industries like healthcare and finance, confidential computing will play an increasingly important role in ensuring data governance and regulatory compliance across the multi-cloud landscape.

Introduction

Imagine you’re working for a large healthcare provider. You have patient data that needs to be processed in the cloud, but you also want to make sure that this data isn’t accessed or tampered with by anyone, including the cloud provider itself. How can you trust that the cloud server is secure before sending sensitive information to it? That’s where remote attestation comes in. It’s like a virtual “security checkpoint” that ensures the environment where your data will be processed is trustworthy.

Now imagine you’re managing thousands of IoT devices in a smart city, such as street lights or traffic sensors, which are constantly sending data back to central systems. You need to know that these devices haven’t been compromised by hackers. Remote attestation (specifically, RATestation)  helps verify that these devices are secure and haven’t been tampered with, ensuring reliable and secure communication.

Remote attestation is a core component of Confidential Computing that helps verify the integrity of a processing environment in both cloud and IoT setups, building trust across these systems. 

As organizations increasingly adopt cloud and distributed systems, securing sensitive data has become more critical than ever. Remote attestation, a core component of Confidential Computing, verifies the integrity of a data processing environment before sensitive workloads are accessed. This technology builds trust across multi-cloud environments by ensuring workloads run securely within Trusted Execution Environments (TEEs). However, this need for security also extends to the rapidly growing Internet of Things (IoT), where secure real-time operations are crucial.

Remote Attestation in Cloud and IoT: The Key to Secure Data Processing

Remote attestation operates differently in cloud and IoT environments, but its core function remains the same: verifying that a piece of code or application is running inside a secure, trusted environment (TEE).

In cloud computing, remote attestation assures that sensitive workloads, such as financial transactions or healthcare data, are processed securely within TEEs. In IoT, where devices operate in often uncontrolled environments, remote attestation ensures that each device remains trustworthy and untampered with, allowing it to communicate securely with cloud services or other devices.

Confidential Computing for Cloud: In cloud computing, multi-cloud architectures require trust across several infrastructures. Remote attestation ensures that sensitive workloads run in verified TEEs, providing a secure way to meet strict compliance requirements such as GDPR and HIPAA.

Confidential Computing for IoT: Real-Time Security: In IoT environments, remote attestation ensures the continuous integrity of distributed devices. For example, connected medical devices or autonomous vehicles must maintain their trustworthiness during real-time operations. Remote attestation allows organizations to verify these devices dynamically, preventing compromised systems from accessing sensitive networks.

Several CCC projects actively contribute to remote attestation in cloud and IoT:

• Gramine: Primarily focused on Intel® SGX, Gramine supports secure workload execution across multi-cloud infrastructures, providing compatibility for legacy applications that require trusted execution environments.

• Veraison: This flexible framework verifies attestation evidence from TEEs across multiple architectures, validating the integrity of both cloud and IoT devices.

• Keylime: Particularly useful in IoT environments, Keylime offers remote boot attestation and real-time integrity monitoring, ensuring that IoT devices maintain a secure status during operations.

• SPDM Tools: Developed to secure TEE-I/O in both cloud and IoT, SPDM Tools verify that communications between devices remain secure within trusted execution environments.

• Open Enclave SDK: This project abstracts hardware differences and provides a unified API for building secure enclave applications, supporting both cloud-based and IoT use cases.

For more information on all of these projects, see the links below and visit our CCC Project Portfolio. 

How Remote Attestation Ensures Compliance with Global Data Privacy Laws

In industries governed by stringent data privacy laws such as GDPR (General Data Protection Regulation) in Europe and HIPAA (Health Insurance Portability and Accountability Act) in the US, compliance is a top priority. Remote attestation plays a pivotal role in ensuring that sensitive data is processed securely, in compliance with global privacy regulations.

1. GDPR Compliance: Remote attestation ensures that personal data is processed in verified, secure TEEs, preventing unauthorized access or tampering. This is particularly critical for organizations in Europe, where GDPR mandates stringent data protection and privacy standards. The ability to verify the integrity of the cloud infrastructure before processing data allows organizations to prove compliance during audits.
2. HIPAA Compliance: In the healthcare sector, remote attestation is essential for ensuring that sensitive patient data is processed securely in environments that comply with HIPAA. By confirming the integrity of the TEE, healthcare providers can securely manage electronic health records (EHRs), ensuring that patient data remains protected during transmission and processing.

Remote attestation provides organizations with the assurance that sensitive data is handled within secure environments that comply with privacy laws. As multi-cloud and IoT networks grow, ensuring compliance with these laws through verified environments will become even more critical.

Real-Time Trust in IoT: The Importance of Continuous Attestation

The challenge in IoT environments lies in ensuring that every device continuously adheres to security standards. For example, Keylime enables real-time integrity monitoring, ensuring that compromised IoT devices can be detected and isolated immediately. This is especially crucial in industries like healthcare, where real-time decision-making is directly influenced by the security status of devices.

The Future of Remote Attestation: From Cloud to Edge

Remote attestation is evolving to meet the demands of both cloud and IoT environments. As organizations adopt more complex multi-cloud infrastructures and IoT networks, the role of remote attestation will expand. Post-quantum cryptography and enhanced security measures such as multi-party attestation will improve the scalability of remote attestation in the future, making it more robust against emerging threats.

Conclusion: Building Trust with Remote Attestation

Remote attestation is a crucial tool for building trust in both cloud and IoT environments. Whether securing sensitive workloads in multi-cloud infrastructures or maintaining the integrity of millions of IoT devices, remote attestation ensures that data is processed in trusted, verified environments. CCC open-source projects such as Veraison, Gramine, Keylime, and SPDM Tools are leading the way in making remote attestation scalable and secure. As Confidential Computing continues to evolve, remote attestation will remain a cornerstone for ensuring security and trust across distributed systems.

Origin and Motivations Behind ATtestation

The RATtestation documentation emerged from the need to standardize remote attestation protocols across diverse Confidential Computing environments. The document addresses the challenge of securely verifying the integrity of systems in distributed and multi-cloud architectures. ATtestation defines best practices for trust establishment, data protection, and secure communication, ensuring the integrity of Trusted Execution Environments (TEEs). It emphasizes the role of remote attestation in enabling secure collaboration while maintaining compliance with privacy regulations such as GDPR and HIPAA.
