Signal Braces For Quantum Age With SPQR Encryption Upgrade

BrianFagioli shares a report from NERDS.xyz: Signal has introduced the Sparse Post Quantum Ratchet (SPQR), a new upgrade to its encryption protocol that mixes quantum safe cryptography into its existing Double Ratchet. The result, which Signal calls the Triple Ratchet, makes it much harder for even future quantum computers to break private chats. The change happens silently in the background, meaning users do not need to do anything, but once fu…
