Let’s Encrypt plans to pursue a post-quantum-safe Web PKI through Merkle Tree Certificates (MTCs), a new approach that adds post-quantum authentication to the web without sacrificing the speed and reliability that have made TLS universal. The project i…
In this Help Net Security video, Garfield Jones, SVP Global Strategy and Research, QuSecure, lays out what CISOs should do over the next 24 months. A recent Google paper moved the expected arrival of a cryptographically relevant quantum computer from 2…
Consider the history of any recent corporate scandal, and it is quite possible to guess what the story…
Apple has published its post-quantum cryptography implementations in corecrypto, together with mathematical proofs and verification tools for independent expert evaluation, allowing external researchers to review the work and reproduce the company’s an…
Discord has protected voice and video calls in DMs, group DMs, voice channels, and Go Live streams with end-to-end encryption (E2EE) by default. The company began experimenting with E2EE for voice and video in 2023, starting a long-term effort. End-to-…
