Apple Fortifies iMessage Privacy With Post-Quantum Encryption
-
Apple is adding post-quantum encryption called PQ3 to iMessage to defend against future quantum computing attacks. It's the first large-scale messaging protocol with this level of security.
-
PQ3 uses a hybrid model combining elliptic curve cryptography (ECC) and post-quantum cryptography for robust security against current and future threats.
-
It integrates the Kyber algorithm, which is recognized by experts as a solid post-quantum cryptography choice.
-
A key innovation is periodic regeneration of quantum-resistant keys to recover from any compromises and regain secure status.
-
Adding PQ3 encryption sets a new industry standard for security in large-scale messaging platforms that others may follow.
