2. Now generally available: Confidential VM with Intel TDX on the C3 machine series
We’re proud to announce that Confidential VMs are now generally available on the general-purpose C3 machine series with Intel® Trust Domain Extensions (Intel® TDX) technology. Confidential VMs with Intel TDX technology use hardware-based memory encryption to help ensure your data and applications can’t be read or modified while in use.
Enabling confidential computing on a C3 VM requires no code changes. These hardened VMs offer remote attestation so you can verify your VM is running in a TEE with Intel Trust Authority or your own attestation service. The C3 machine series is powered by the 4th generation Intel Xeon Scalable processors (code-named Sapphire Rapids), DDR5 memory, and Google Titanium.
Built-in CPU acceleration with Intel AMXAll C3 VMs, including Confidential VM ones, have Intel® Advanced Matrix Extensions (Intel® AMX) on by default. Intel AMX is a new instruction set architecture (ISA) extension designed to accelerate artificial intelligence (AI) and machine learning (ML) workloads. AMX introduces new instructions that can be used to perform matrix multiplication and convolution operations, which are two of the most common operations in AI and ML. By combining Confidential VMs with Intel AMX, you can run AI/ML applications with an additional layer of security.

4. Signed UEFI binaries for Confidential VMs with AMD SEV-SNP and Intel TDX
We’re excited to announce a significant security enhancement to our Confidential VMs powered by AMD SEV-SNP and Intel TDX technologies: signed launch measurements (UEFI binary and initial state). UEFI is the firmware that controls the startup process of a computer, and by signing these binaries, we’ve added an extra layer of protection against unauthorized modifications or tampering.
Signing the UEFI and allowing you to verify the signatures can help you gain more trust and transparency that the firmware running on your Confidential VMs is genuine and hasn’t been compromised. By verifying the firmware’s authenticity and integrity, you can be more confident that your attested devices are running in a secure and trusted environment.
This is just one of many steps Google plans on taking to build a more verifiably trustworthy and secure system. To try it out yourself, see Verify Firmware.
5. Google Cloud attestation now supports Confidential VM with AMD SEV
If your trust model allows it, instead of writing and running an attestation verifier yourself, you can use the Google Cloud attestation service. To do so, use Go-TPM tools to retrieve an attestation quote from an AMD SEV Confidential VM instance’s vTPM, and send it to the Google Cloud Attestation service for verification with the command ./go-tpm token.
If the attestation quote passes verification, the Google Cloud Attestation returns a token containing VM information that you can then compare against your own policy to confirm whether or not the VM should be trusted. Currently,Google’s attestation service supports AMD SEV only.
