en.Wedoany.com Reported - Apple has announced the first expansion of its Private Cloud Compute security architecture to third-party data centers. Apple Intelligence features will not only run on Apple's own hardware but will also be deployed on Google Cloud systems equipped with NVIDIA GPUs.

This architecture, named Private Cloud Compute (PCC), was initially launched in 2024 to protect artificial intelligence requests sent to the cloud due to their complexity exceeding the local processing capabilities of devices. Its core principle is that data sent to the cloud to handle more complex Apple Intelligence functions is processed only for specific requests and is not stored permanently.

For this expansion plan, Apple is collaborating with Google and NVIDIA. Google provides infrastructure and model technologies related to the Gemini series, while NVIDIA offers GPUs with confidential computing capabilities. Additionally, Apple is using Intel Xeon processors with Trust Domain Extensions and Google's Titan chips. The goal is to execute more complex AI tasks (such as complex reasoning or agent-like tool usage) outside Apple's own data centers without compromising the security commitments of the existing PCC. Previously, Private Cloud Compute ran entirely on Apple Silicon servers within Apple's own infrastructure.

Apple emphasizes that the core requirements of PCC remain unchanged, including stateless processing, no privileged runtime access, prevention of targeted correlation for individual user requests, and verifiable transparency. Even in the Google Cloud environment, Apple devices only trust PCC software authorized by Apple's encryption. According to Apple, it retains full control over the software.

On the technical side, Apple describes this new implementation as a multi-layered security model. A publicly verifiable, append-only registry will record which Google Cloud hardware belongs to the PCC cluster; this registry can only have information added and cannot be modified retroactively without detection. For critical components, Apple also plans to base authentication on at least two mutually independent trust characteristics. The processing of individual requests also uses isolation mechanisms: initial network data will be processed in a separate process with its own namespace, shared inference software runs only briefly, and keys are stored in isolated confidential virtual machines.

Apple announced that, like PCC running on Apple Silicon, this expansion will also make all files available for public review. Additionally, Apple will provide research tools through its security bounty program, as well as access to live PCC nodes in research mode. More technical details will be released later this year, and starting in July, PCC on Google Cloud will gradually reach full protection scope.
