I recently came across this blog post from Zoom that announced that it is now adopting Post-Quantum End-to-End Encryption for its Video Conferencing services.

It all started with Signal adapting the Post Quantum XDH (PQXDH) Key Agreement Protocol in 2023, becoming the first large-scale message app to do so.

This was soon followed by Apple adopting PQ3, a post-quantum cryptographic protocol for securing iMessage, in February 2024.

Finally, Zoom is now the first UCaaS (Unified Communications as a Service) company to adopt this security feature!

This means that from now on, users can ensure that their Zoom meetings are kept completely private and encrypted using advanced algorithms.

These algorithms make sure that apart from the participants of the meeting, no external parties, hackers or even Zoom itself, can gain access to the meeting content.

What’s special about these e…
