#signal To add post‑quantum security, Signal introduced the Sparse Post‑Quantum Ratchet #SPQR , which runs alongside the existing #DoubleRatchet
The protocol now effectively combines three components: the symmetric ratchet, the classical DH ratchet, and the new post‑quantum ratchet (SPQR).

SPQR — наше опенсорс-решение для горизонтального масштабирования Postgres
В современных реалиях объёмы данных постоянно растут и появляются всё более жёсткие требования к производительности. Тут традиционный PostgreSQL сталкивается с фундаментальной проблемой: отсутствие нативной поддержки горизонтального масштабирования. Сегодня мы, команда платформы данных в Yandex Cloud, хотим рассказать о SPQR — нашем опенсорс‑инструменте, который который создавался как ответ на боль шардирования и эксплуатации крупных OLTP‑систем. Под катом — история о том, что стало отправной точкой для его создания, какие задачи он помогает решать, на чём основано наше решение и что помогает ему быть довольно простым в эксплуатации.

Anyone else worried about #SPQR encryption, simply because of the chosen acronym?
Someone is laughing their ass off about the fact that we don't seems concerned with encryption called #SPQR...
...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: 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.
#signal #sparse #postquantum #ratchet #spqr #it #security #privacy #engineer #media #tech #news
![⁉️The new component guarantees forward secrecy and post-compromise security, ensuring that even in the case of key compromise or theft, future messages exchanged between parties will be safe.⁉️
In terms of cryptography, SPQR utilizes post-quantum Key-Encapsulation Mechanisms [ML-KEM] instead of elliptic-curve Diffie-Hellman, and features efficient chunking and erasure coding to handle large key sizes without bloating bandwidth. Signal has been using CRYSTALS-Kyber [a post-quantum KEM] alongside an implementation of the Elliptic Curve Diffie-Hellman since 2023 to protect against quantum computing attacks that threaten to break current encryption.
👾However, SPQR comes on top of the existing double ratchet system, forming what Signal calls a Triple Ratchet, formulates a hyper-secure “mixed key.”👾
The new system was designed in collaboration with PQShield, AIST [Japan] and New York University, with its technical foundation based in part on USENIX 2025 and Eurocrypt 2025 papers. The design was also formally verified using ProVerif, and the Rust implementation robustness was tested using the hax tool. Continuous verification will now be applied to all future builds, ensuring proofs are reproduced with every code change.
⚠️Signal says the rollout of SPQR on the messaging platform will be gradual, and users don’t need to take any action for the upgrade to apply apart from keeping their clients updated to the latest version.⚠️](https://files.mastodon.social/cache/media_attachments/files/115/446/434/840/414/740/original/97454797570eeb94.jpeg)

Signal bringt Post-Quanten-Schutz, bleibt aber beim Gerätewechsel unpraktisch
Signal bietet jetzt fortschrittlichen Schutz gegen zukünftige Quantencomputing-Gefahren. Trotzdem ist der Wechsel auf ein anderes Smartphone mit Signal weiterhin wenig

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'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 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.
#privacy #security
I love the name #SPQR too. Security for the senate, as well as the people 😂
