Apple has recently unveiled a significant enhancement to iMessage’s cryptographic security — the rollout of PQ3, a post-quantum cryptographic protocol.

This pioneering development raises iMessage to what Apple terms ‘Level 3 security,’ a benchmark unparalleled by any other widely used messaging application currently available.

So, will it protect our undressed pictures from being leaked if shared on iMessage…wait a minute. Do not share such pictures to your partner or anyone on iMessage or any other platform. Yes, I’m talking to you.

Anyway, let’s explore further insights into this PQ3 encryption.

The Quantum Computing Threat Versus PQ3

Traditionally, messaging platforms have depended on classical public key cryptography such as RSA and Elliptic Curve cryptography, both of which face a threat due to the emergence of quantum computing. A quantum computer with adequate power could theoretically solve these classical mathematical problems quickly, posing a risk to end-to-end encrypted communications.

To prepare for the quantum computing era, PQ3 is crafted as a post-quantum cryptography…
