Recently, the team led by Prof. Zeng-Bing Chen and Prof. Hua-Lei Yin have successfully, for the first time, realized transmission of megabit images with information-theoretical non-repudiation for ...

A breakdown of what type of risks quantum computing poses to Bitcoin, and how worried users of the network should be. In the early 2020s, quantum computing hit the public spotlight as a potential ...

Scientists develop a chaos-based stream cipher that can withstand attacks from large-scale quantum computers. Fast algorithms on quantum computers could easily break many widely used cryptosystems, ...

Many discussions of “hybrid encryption” begin with some debate about just what this means. Hybrid encryption in general refers to the combined use of public-key (asymmetric) cryptography with ...

Alex Pruden said the asymmetry between acting on a post-quantum signature scheme today and waiting for certainty about quantum-computing hardware timelines means Bitcoin developers should move from ...

Quantum threat concerns are gaining attention after Coinbase released a new report warning that while digital assets remain secure today, the industry must begin preparing for future risks tied to ...

I won’t pretend to deeply understand quantum physics, or quantum computing specifically, I don’t, but I grasp enough to know that the theory underlying it is sound. For certain classes of ...

Public-key cryptography can become unreliable in certain post-Q-Day scenarios. The earliest onchain stress is likely to concentrate in digital signatures (authorization and ownership) because they ...
