The Unofficial Guide to Apple’s Private Cloud Compute - Jmo, CONFSEC

In October 2024, Apple released a new private AI technology onto millions of devices called “Private Cloud Compute”. It brings the same level of privacy and security a local device offers but on an “untrusted" remote server. This talk discusses how Private Cloud Compute represents a paradigm shift in confidential computing and explores the core advancements that made it possible to become mainstream. We’ll explore its novel architecture that allows developers to run sensitive, multi-tenant workloads with cryptographically-provably privacy guarantees at scale and at reasonable cost. Attendees will leave with an understanding of how to leverage this technology for data and AI applications where privacy and security is paramount.
