What Is Confidential Computing? And What Role Does It Take In Data Partnerships?​

In today’s digital age, data is a valuable asset. However, much of this data is sensitive and protected, whether it’s proprietary business information or personal data. From safeguarding personal data to ensuring the security of proprietary information, organizations across the globe face a significant challenge: how to extract valuable insights from sensitive data while keeping it secure and maintaining its privacy.

Confidential computing is a new technology that can help solving this challenge. It enables data processing while providing a hard proof of isolation. This can be leveraged to keep data confidential while in use, allowing computations to occur in a safe environment that cannot be tampered even by the owner of the bare metal.

What is Confidential Computing?

Confidential computing introduces a secure environment known as a trusted execution environment (TEE). This environment can be a physically separate part of a computer or a protected area within the computer’s main processor. The TEE is designed to run computations in an isolated and verifiable manner, ensuring that the data remains private. Encrypting data at rest and in transit is standard practice, but confidential computing takes it a step further by keeping data encrypted while in use. This ensures that data remains private throughout its entire lifecycle.

Key Security Measures: Isolation and Verification

Two key security principles underpin confidential computing: isolation and verification.

Isolation: The TEE keeps computations completely separate from other operations on the computer. The separation is so significant, such that even the operating system, system administrators, and individuals with physical access to the computer cannot access the information inside the TEE. This robust isolation dramatically increases trust between collaborating parties, especially in remote or cloud-based environments. Indeed, each of the hyperscalers has confidential-computing-enabled virtual machines available for use. Moreover, cloud service providers consider confidential computing as an important technology that would drive more enterprises to migrate to the cloud, as it lowers the required trust level between CSPs and their customers.

Verification: A TEE can provide a proof about its secure state by running a verification process dubbed attestation. In essence, the attestation process is comprised of gathering verifiable information by the hardware about the system state. The attestation process also involves the hardware manufacturer (like Intel or AMD) in the loop, which makes it extremely robust and difficult to compromise.

Real-World Applications

Confidential computing is not just a futuristic concept; it is already part of our daily lives. For example, mobile devices use TEEs to securely process your biometric data. Today, some of the most promising applications of confidential computing are designed to make the best use of sensitive data while protecting it. For example, Apple Intelligence uses confidential computing in its ‘Private Cloud Compute’ to build user-specific LLMs using the user’s sensitive data.

At Multyx, we harness the power of confidential computing to unlock the potential of data and AI applications previously deemed too risky due to confidentiality concerns. Consider a scenario where multiple organizations wish to collaborate on sensitive data. Using Multyx, they can securely analyze data collectively, ensuring that only approved results are shared while the data itself remains inaccessible to non-owners. By ensuring both confidentiality and utility, confidential computing paves the way for analytics that were once hindered by mistrust and regulatory challenges.

Final Thoughts

Confidential computing is a paradigm shift in how we approach data security and collaboration. Leveraging the appropriate software stack, enterprises can securely and efficiently extend their trust perimeter beyond traditional firewall constraints, enabling novel forms of computation across distributed and potentially untrusted environments. Businesses that embrace this paradigm shift will lead the way in unlocking the full value of their data. At Multyx, we’re proud to be at the forefront of this transformation, helping organizations turn challenges into opportunities through the power of confidential computing.
