Zoom introduces quantum-safe encryption

Post-quantum end-to-end encryption is now available for Zoom Meetings and will soon come to Zoom Phone and Zoom Rooms.

The video conferencing firm said the post-quantum end-to-end encryption will protect users from “harvest now, decrypt later” attacks.

Such attacks include threat actors capturing encrypted network traffic now in hopes of decoding it later once powerful quantum computers capable of doing so become available.

Zoom introduced end-to-end encryption for Zoom Meetings in 2020 and Zoom Phone in 2022. It said customers were increasingly using this safety feature.

By launching post-quantum encryption, the firm is “doubling down on security and providing leading-edge features for users to help protect their data,” said Michael Adams, chief information officer at Zoom.

According to Zoom, both post-quantum and standard encryption that it offers are based on the system designed to provide only the participants with access to the encryption keys that are used to encrypt the meeting.

Because Zoom’s servers do not have the necessary decryption key, encrypted data relayed through its servers is “indecipherable,” the company said.

Zoom’s post-quantum encryption uses Kyber 768, one of several quantum-proof algorithms being standardized by the National Institute of Standards and Technology (NIST).

Other companies have also moved to future-proof their systems. Signal, a messenger app, introduced quantum-proof encryption last year, and so did search giant Google.

Meanwhile, the city-state of Singapore picked two local companies that will collaborate with electronics company Toshiba to build Southeast Asia’s first quantum-safe network.
