Post-Quantum Cryptography Coalition Launches
On 26 Sep 2023: The data we're encrypting online today—from financial and personal identification information to military operations and intelligence data—could be quickly decrypted in the future by an adversary with access to a cryptographically relevant quantum computer. To drive progress toward broader understanding and public adoption of post-quantum cryptography (PQC) and the National Institute of Standards and Technology's (NIST) PQC algorithms, a community of technologists, researchers, and expert practitioners launched the PQC Coalition. Founding coalition members include IBM Quantum, Microsoft, MITRE, PQShield, SandboxAQ, and University of Waterloo. - mitre.org
Signal adds quantum-resistant encryption to its E2EE messaging protocol
On 25 Sep 2023: Signal has announced that it upgraded its end-to-end communication protocol to use quantum-resistant encryption keys to protect users from future attacks.
Signal explains that its "X3DH" (Extended Triple Diffie-Hellman) key agreement protocol has been upgraded to "PQXDH" (Post-Quantum Extended Diffie-Hellman), which incorporates quantum-resistant secret key generation mechanisms for Signal's end-to-end encryption (E2EE) specification. - bleepingcomputer.com
