"Signal Upgrades Encryption to Ward off Quantum Attacks"

Signal, the telecommunications app, has announced an upgrade to its cryptographic specifications aimed at withstanding a potential future cyberattack involving quantum computers. On September 19, Signal announced an upgrade to the X3DH specification called PQXDH, which is the first step in advancing quantum resistance for its dedicated protocol. With this upgrade, Signal is adding a layer of protection against the threat posed by a future quantum computer powerful enough to break current encryption standards. Quantum computing is expected to revolutionize certain sciences and technologies in the transport, energy, and medical sectors, but it will render the RSA Cryptosystem obsolete. This article continues to discuss Signal upgrading its cryptographic specifications to withstand a potential future cyberattack by a threat actor using quantum computers.
