A Beefed-Up Quantum-Proof Signal Messenger App for Journalists & Individuals Requiring Privacy

Now, Signal Messenger is considered the gold standard for private, secure, and encrypted messaging.

In today's world, journalists are at risk of being killed for exposing the truth and challenging certain governments. Therefore, it is crucial for them to use the best encryption messaging systems to share their findings with the public. In 2023, approximately 45 journalists were killed for these reasons. Reporters Without Borders (RSF), an international non-profit organization, recommends that all journalists use Signal Messenger, regardless of whether they work in a modern liberal democracy or an authoritarian regime.

With the advancement of quantum computing and artificial intelligence, many governments seek quicker access to decrypt encrypted messages and documents to uncover national secrets or information that journalists may possess through intermediaries.

Signal is trying to stay ahead of the game by upgrading its encryption to be quantum-proof...

Encrypted messaging app Signal has announced an update to the Signal Protocol to add support for quantum resistance by upgrading the Extended Triple Diffie-Hellman (X3DH) specification to Post-Quantum Extended Diffie-Hellman (PQXDH).

"With this upgrade, we are adding a layer of protection against the threat of a quantum computer being built in the future that is powerful enough to break current encryption standards," Signal's Ehren Kret said.

The development comes weeks after Google added support for quantum-resistant encryption algorithms in its Chrome web browser and announced a quantum-resilient FIDO2 security key implementation as part of its OpenSK security keys initiative last month.
