Apple Rolls Out iMessage Upgrade To Withstand Decryption By Quantum Computers

Apple is rolling out an upgrade to its iMessage texting platform to defend against future encryption-breaking technologies. From a report: The new protocol, known as PQ3, is another sign that U.S. tech firms are bracing for a potential future breakthrough in quantum computing that could make current methods of protecting users' communications obsolete. "More than simply replacing an existing algorithm with a new one, we rebuilt the iMessage cryptographic protocol from the ground up," an Apple blog post published on Wednesday reads. "It will fully replace the existing protocol within all supported conversations this year." The Cupertino, California-based iPhone maker says its encryption algorithms are state-of-the-art and that it has found no evidence so far of a successful attack on them. Still, government officials and scientists are concerned that the advent of quantum computers, advanced machines that tap in to the properties of subatomic particles, could suddenly and dramatically weaken those protections. Late last year, a Reuters investigation explored how the United States and China are racing to prepare for that moment, dubbed "Q-Day," both by pouring money into quantum research and by investing in new encryption standards known as post-quantum cryptography. Washington and Beijing have traded allegations of intercepting massive amounts of encrypted data in preparation for Q-Day, an approach sometimes dubbed "catch now, crack later."
