Apple Says It Has Rebuilt The iMessage Cryptographic Protocol From ‘Ground Up’ To Thwart Quantum Computing Threat

In a bid to fortify its messaging platform against potential quantum computing decryption, Apple Inc. (NASDAQ:AAPL) has introduced a new security upgrade for iMessage .

What Happened: The new security protocol, dubbed PQ3, is a significant overhaul of the iMessage cryptographic protocol. This move is indicative of U.S. tech companies preparing for the potential impact of quantum computing on current encryption methods, reported Reuters.

The Cupertino, California-based tech giant asserts that its encryption algorithms are cutting-edge and have not been successfully breached. However, the emergence of quantum computers, which leverage the properties of subatomic particles, have become a subject of concern for government officials and scientists.

“More than simply replacing an existing algorithm with a new one, we rebuilt the iMessage cryptographic protocol from the ground up,” Apple stated in a blog post on Wednesday. “It will fully replace the existing protocol within all supported conversations this year.”

Why It Matters: The development of quantum-resistant encryption is a crucial step for tech companies, as quantum computers could potentially render current encryption methods obsolete. This upgrade by Apple is a proactive measure to address the potential threat posed by quantum computing, the report noted.
