...users of #Signal and other messengers relying on the #SignalProtocol need not concern themselves with any of these new designs. To paraphrase a certain device maker, it just works.

Signal adds new Cryptographic Defense against Quantum Attacks.
Signal announced the introduction of Sparse Post-Quantum Ratchet [SPQR], a new cryptographic component designed to withstand quantum computing threats. SPQR will serve as an advanced mechanism that continuously updates the encryption keys used in conversations and discarding the old ones.

Seriously, @signalapp? You named your "triple ratchet" crypto #SPQR? Was "we love imperialism and anti-democratic militarism, thank you Open Technology Fund for funding us to help out the NSA" already taken as an acronym?!

We are excited to announce a significant advancement in the security of the Signal Protocol: the introduction of the Sparse Post Quantum Ratchet (SPQR). This new ratchet enhances the Signal Protocol’s resilience against future quantum computing threats while maintaining our existing security guar...
We're excited to see the release of Signal's new post-quantum ratcheting protocol, SPQR!
We are proud to have collaborated with the Signal team on the formal analysis of the design and implementation of this new feature.

Maailman käytetyin pikaviestinten salausprotokolla Signal Protocol vahvistui
Protokollaa uudistettiin ns. salauksen maailmanloppua ajatellen, eli kvanttilaskennan tuomia haasteita varten.
Signal Protocol on käytössä mm. Signalissa, WhatsAppissa sekä Androidin RCS-viesteissä.

Signal Protocol on salausprotokolla, jota käytetään mm. Signalissa, WhatsAppissa sekä Googlen RCS-tekstiviesteissä. Nyt protokollaa on uudistettu aiempaakin paremmin kestämään kvanttilaskennalla tehdyt hyökkäykset.
#Signal Braces For #Quantum Age With #SPQR #Encryption Upgrade - Slashdot
Signal has introduced the #SparsePostQuantumRatchet (SPQR), a new upgrade to its #encryption protocol that mixes quantum safe #cryptography into its existing #DoubleRatchet. The result, which Signal calls the #TripleRatchet , makes it much harder for even future quantum computers to break private chats.
