Secure and private AI processing in the cloud poses a formidable new challenge. To support advanced features of Apple Intelligence with larger foundation models, we created Private Cloud Compute (PCC), a groundbreaking cloud intelligence system designed specifically for private AI processing. Built with custom Apple…
We are introducing PQ3, a groundbreaking cryptographic protocol for iMessage that advances the state of the art of end-to-end secure messaging. With compromise-resilient encryption and extensive defenses against even highly sophisticated quantum attacks, PQ3 provides protocol protections that surpass those in all…
Introducing Apple Reference Image, a new solution for verifiable photography on iPhone. This new, opt-in camera mode lets a photographer create a securely timestamped reference image that accurately depicts what was captured by the iPhone's camera sensor. Apple Reference Image offers a trustworthy, scalable guarantee…
Memory Integrity Enforcement (MIE) is the culmination of an unprecedented design and engineering effort spanning half a decade that combines the unique strengths of Apple silicon hardware with our advanced operating system security to provide industry-first, always-on memory safety protection across our devices …
Private Cloud Compute (PCC) fulfills computationally intensive requests for Apple Intelligence while providing groundbreaking privacy and security protections — by bringing our industry-leading device security model into the cloud. To build public trust in our system, we’re making it possible for researchers to…
Apple’s Security Bounty program has paid nearly $20 million in rewards to security researchers in just two and a half years. Our new site makes it easier than ever for researchers to submit reports on the web, get real-time updates from Apple engineering, and earn recognition for helping to improve security for the…
Improving software memory safety is a key security objective for engineering teams across the industry. Here we begin a journey into the XNU kernel at the core of iOS and explore the intricate work our engineering teams have done to harden the memory allocator and make our software much more difficult to exploit.
With the latest release of corecrypto, we’re publishing our implementations of quantum-secure ML-KEM and ML-DSA algorithms, along with the mathematical proofs we built to assure they are faithful to the FIPS 203 and FIPS 204 specifications. To advance the state of the art for assuring critical software, we're also…
