About
Apple Inc. is an American multinational technology company founded in 1976 and headquartered in Cupertino, California. In February 2024, it introduced PQ3, a post-quantum cryptographic protocol for iMessage, which became the first at-scale messaging system to combine post-quantum and classical key exchange. PQ3 registers a Kyber-1024 (ML-KEM) public key alongside a classical P-256 elliptic-curve key on every device, and mixes a new post-quantum key into the ratchet every 50 epochs. It rolled out across iOS 17.4, iPadOS 17.4, macOS 14.4, and watchOS 10.4. Apple positions PQ3 as Level 3 messaging security, defending against both immediate eavesdropping and harvest-now-decrypt-later attacks. In 2026, Apple extended quantum-secure cryptography system-wide, enabling quantum-secure TLS by default across iOS 26, iPadOS 26, and macOS 26.
