The Guardian launches Secure Messaging, a world-first from a media organisation, in collaboration with the University of Cambridge

www.theguardian.com

Secure Messaging is a new innovation for confidential story-sharing and source protection, underpinning the Guardian’s commitment to investigative journalism. The Guardian has published the open source code for this important tech to enable adoption by other media organisations.

Context: https://bsky.app/profile/martin.kleppmann.com/post/3lr6ex2glkc2h

This system is baked into the Guardian’s news app that millions of people have installed. Every regular user of the app generates cover traffic, and an attacker monitoring the network cannot distinguish someone using the secure messaging feature from a regular user.
