Definition
The term, in context
AI-assisted draft · approved dataset
PQ3 is the messaging protocol Apple uses in iMessage, combining elliptic-curve key agreement with a post-quantum key encapsulation mechanism so that conversations captured today are designed to resist later decryption by a quantum computer. The post-quantum component is applied both when a conversation is established and during periodic rekeying, bounding how much of a conversation any single compromised key exposes.
