Frequently asked questions about “Is encryption enough to protect our data?”
What is "Is encryption enough to protect our data?" about?
In "Is encryption enough to protect our data?" (Technology Now, May 2026), confidential computing secures data even while it's in use, closing the critical vulnerability where information is exposed in system memory. By leveraging specialized hardware enclaves, organizations can prevent malicious insiders and compromised administrators from exfiltrating sensitive data.
What does "Trusted Execution Environment (TEE)" mean in "Is encryption enough to protect our data?"?
In "Is encryption enough to protect our data?", A TEE acts as a digital vault inside the CPU. It ensures that even if the host operating system or a system administrator is compromised, they cannot peer into the memory or manipulate the data currently being processed. As the episode puts it: "The foundation of confidential computing is something called a trusted execution environment."
What does "Data in Use" mean in "Is encryption enough to protect our data?"?
In "Is encryption enough to protect our data?", This is the 'missing link' in modern security. While we have mature methods to secure data on disks and over the network, data in use has traditionally been vulnerable because it must be decrypted to be processed, leaving it exposed to anyone with system-level access.
What does "SPDM (Security Protocol and Data Model)" mean in "Is encryption enough to protect our data?"?
In "Is encryption enough to protect our data?", This protocol is the glue that enables confidential computing across distributed components. It allows for encrypted, authenticated channels between chips, ensuring that data moving through a server chassis cannot be intercepted.
What does "Is encryption enough to protect our data?" say about data remains vulnerable in memory even when encrypted?
In "Is encryption enough to protect our data?", Data remains vulnerable in memory even when encrypted at rest or in transit; confidential computing secures this specific 'in-use' gap. It eliminates the assumption that system administrators should have total, clear-text access to all data they manage.
What does "Is encryption enough to protect our data?" say about the technology relies on 'trusted execution environments'?
In "Is encryption enough to protect our data?", The technology relies on 'trusted execution environments' (TEEs) that measure and sign the running code to ensure it hasn't been tampered with. This provides cryptographic proof that the workload is legitimate before it is granted access to the decryption keys.

Confidential Computing: Protecting Data While It Processes
Confidential computing secures data even while it's in use, closing the critical vulnerability where information is exposed in system memory. By leveraging specialized hardware enclaves, organizations can prevent malicious insiders and compromised administrators from exfiltrating sensitive data.
Bottom line
Confidential computing creates 'trusted execution environments' that ensure data remains encrypted even while being processed, neutralizing the risk of system administrator misuse.
Current security models fail when a trusted insider is compromised, making this technology the next essential layer in enterprise data compliance and protection.
Best moment
Nigel Edwards clearly explains exactly how the virtual machine abstraction keeps data encrypted from malicious system administrators.

Preparing early for the shift toward confidential computing as a regulatory standard avoids reactive infrastructure overhauls in the future.
“Confidential computing uses AES encryption in silicon to protect data in memory, adding only 1-5% performance overhead once hardware acceleration is fully deployed.”
Comprehensive Overview
A 1-minute read.
Confidential computing is emerging as the necessary evolution of zero-trust architecture, specifically addressing the gap in protecting data 'in use'. The fundamental breakthrough is that data remains encrypted throughout the entire processing lifecycle, only being decrypted inside secure processor enclaves. This shift effectively removes the human element of system administration from the threat model, as even someone with root access cannot view the data residing in a confidential virtual machine's memory.
Historically, protecting data in memory was difficult due to the performance penalties involved. However, modern x86 processors now feature hardware-level support for encryption, allowing for minimal performance overhead—typically within the 1-5% range. This makes confidential computing viable for enterprise-scale workloads that were previously limited by latency. The technology relies on a rigorous process called attestation, where the hardware measures the code being executed and signs it with a private key, providing verifiable assurance that the software has not been manipulated.
Looking toward the future, the industry is moving toward standardizing these protocols through bodies like the Confidential Computing Consortium. Experts anticipate that confidential computing will become a regulatory necessity for sensitive data handling within the next five years. This adoption curve will mirror the history of credit card security standards, eventually becoming a default feature of cloud deployment that developers and IT users won't even need to configure manually.
While current implementation requires specific firmware and specialized tooling, the alignment of major hardware vendors around common virtual machine abstractions is accelerating progress. By integrating Post-Quantum Cryptography (PQC) standards such as MLDSA into these firmware protocols, the industry is ensuring these protected enclaves remain secure even in the face of future quantum computing threats.
