How Apple turned to math to defend against next-gen attacks on encryption
Apple is transitioning to post-quantum cryptography to enhance its encryption systems against future quantum computer attacks. The company has developed a custom formal verification system to ensure the reliability of its cryptographic implementations. This effort is crucial as conventional testing methods have proven insufficient for the security needs of over 2.5 billion active devices.
- ▪Apple is implementing post-quantum cryptography to protect against potential future attacks from quantum computers.
- ▪The company has created a formal verification system to ensure its cryptographic code meets official NIST specifications.
- ▪Recent research revealed flaws in traditional testing methods, prompting Apple to adopt mathematical proofs for verification.

Apple says testing missed flaws in new encryption designed to protect against future attacks from quantum computers, so it turned to mathematical proofs to make sure the code works correctly before wider rollout. New research and source code published May 22 detail how Apple verified parts of its post-quantum cryptography stack. The research argues conventional software testing is good, but no longer provides sufficient guarantees for encryption systems used across more than 2.5 billion active devices.
