Apple’s privacy-focused cloud AI approach will be among the most secure available
Apple will reportedly rely on its own proprietary Secure Enclave in its M2 Ultra and M4 chips to process cloud AI requests without compromising users’ privacy.
Apple’s Secure Enclave is a dedicated secure subsystem in the latest versions of iPhone, iPad, Mac, Apple TV, Apple Watch, and HomePod. The Secure Enclave Processor runs an Apple-customized version of the L4 microkernel. It’s designed to operate efficiently at a lower clock speed that helps to protect it against clock and power attacks. The Secure Enclave Processor, starting with the A11 and S4, includes a memory-protected engine and encrypted memory with anti-replay capabilities, secure boot, a dedicated random number generator, and its own AES engine.
No other tech firm can offer Apple’s Secure Enclave.
Typically, cloud services encrypt data when stored, but in order to process data, it must be decrypted. iCloud already uses a mix of in transit, on server and end-to-end encryption across its services depending on the level of protection users choose.
Apple’s solution for upcoming AI services, says The Information, is to upscale its Secure Enclave technology which isolates sensitive data in order to enable private processing in the cloud.
The approach looks to be linked to the Apple Chips in Data Centers project – a project that will see Apple develop its own chips to run AI services in data centers.
Recent reports indicate that the company has been rolling out M2 Ultra chips across its cloud infrastructure, with plans to upgrade to M4 chips on the horizon.

MacDailyNews Take: Expect Apple to say “privacy” or “security” at least as many times as they say “AI” in their WDC24 Keynote Address video.
