4+ day, 11+ hour ago   (1400+ words) Bitcoin’s post-quantum migration debate has moved toward wallet security and dormant-coin handling after Ledger CTO Charles Guillemet argued that choosing a new signature scheme may prove easier than moving Bitcoin users and existing funds safely. His review focuses on SHRINCS,…...

6+ day, 6+ hour ago   (336+ words) An international team of researchers, including Professor David Oswald from our Department of Computer Science, has discovered a security vulnerability that could put sensitive data stored in cloud computing systems at risk. The research, led by Belgian university KU Leuven,…...

1+ week, 2+ day ago   (723+ words) In recognition of World Quantum Readiness Day, an ASU expert discusses quantum computing, AI and the future of cybersecurity Most people trust that the passwords, bank accounts, medical records and private messages they use every day are protected by encryption....

1+ week, 2+ day ago   (820+ words) Post-quantum security is neither a product nor a date, but a set of new algorithms with larger keys and a handshake that carries two kilobytes more. It is also an inventory that has to stay current, and a small number…...

1+ week, 4+ day ago   (474+ words) You cannot protect what you cannot see. Transitioning to post-quantum resilience begins with uncovering hidden cryptographic debt. By transforming your network into a distributed sensor, you gain the clarity needed to identify every vulnerable protocol and secure your digital foundation....

1+ week, 6+ day ago   (350+ words) Quantum Readiness Day on 24 September is a useful reminder that the security work we do today is not only about preventing breaches tomorrow. It is about protecting data and digital trust for years to come. Quantum readiness is industry-wide because…...
