Signal geht mit der Einf\u00fchrung des Sparse Post Quantum Ratchet (SPQR) einen weiteren Schritt, um das Signal-Protokoll widerstandsf\u00e4hig gegen Quantenangriffe zu machen. Dieses Upgrade sch\u00fctzt deine Nachrichten vor der Bedrohung durch zuk\u00fcnftige Quantencomputer.<\/strong><\/p>\n\n\n\n

Wie du wei\u00dft, ist, bei Signal alles standardm\u00e4\u00dfig Ende-zu-Ende-verschl\u00fcsselt<\/a>. Das bedeutet, dass Nachrichten von niemand anderem gelesen werden k\u00f6nnen. M\u00f6glich wird das durch das Signal-Protokoll, das f\u00fcr seine starke Verschl\u00fcsselung bekannt ist, die von herk\u00f6mmlichen Computern nicht geknackt werden kann. In den letzten Jahren hat sich jedoch die Entwicklung von Quantencomputern deutlich beschleunigt. W\u00e4hrend die aktuelle Generation keine Gefahr f\u00fcr Signal darstellt, erwarten Expert*innen, dass zuk\u00fcnftige Quantencomputer irgendwann leistungsf\u00e4hig genug sein k\u00f6nnten, um selbst die heutige Verschl\u00fcsselung zu brechen.<\/p>\n\n\n\n

Deshalb arbeitet Signal seit Jahren daran, das Signal-Protokoll widerstandsf\u00e4hig gegen Quantenangriffe zu machen. Im Jahr 2023 f\u00fchrte Signal das PQXDH-Upgrade<\/a> als erstes Post-Quantum-Update ein, um Chats besser vor zuk\u00fcnftigen Quantencomputern zu sch\u00fctzen. Jetzt k\u00fcndigt Signal das n\u00e4chste gro\u00dfe Update an: den Sparse Post Quantum Ratchet (SPQR)<\/a>.<\/p>\n\n\n\n

Sparse Post Quantum Ratchet (SPQR) ein<\/h2>\n\n\n\n

Das neue Update erg\u00e4nzt den bestehenden Double Ratchet<\/a> Algorithmus um den Sparse Post Quantum Ratchet. Gemeinsam bilden sie den neuen Triple Ratchet, der sicherstellt, dass Nachrichten auch in Zukunft quantensicher verschl\u00fcsselt bleiben.<\/p>\n\n\n\n

F\u00fcr Nutzer*innen \u00e4ndert sich nichts: Gespr\u00e4che werden automatisch auf das neue, quantenresistente Signal-Protokoll umgestellt, sobald es verf\u00fcgbar ist \u2013 so bleiben Nachrichten sowohl jetzt als auch in Zukunft sicher.<\/p>\n\n\n\n

Mit diesem Update bleibt Signal f\u00fcr das Zeitalter der Quantencomputer ger\u00fcstet und gew\u00e4hrleistet gleichzeitig weiterhin die Privatsph\u00e4re und Sicherheit der Nutzer*innen.<\/p>\n\n\n\n

In einem ausf\u00fchrlichen Blogpost gehen Graeme Connell und Rolfe Schmidt von Signal n\u00e4her auf die technischen Details des Sparse Post Quantum Ratchet (SPQR) ein<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"
