Recently updated advice on quantum security technologies from the UK NCSC is bluntly sceptical about the promised benefits of quantum key distribution. This seems at odds with the scramble of governments around the world to promote the development of quantum networking technologies. Who is right? Future large scale quantum computers will one day bring many…
Future quantum computers will ultimately force blockchain solutions to adopt strengthened quantum safe crypto protocols. Rationally there remains plenty of time to act, but proponents need to get their transition stories in place to avoid being caught out as we near peak quantum hype. More positively, the nascent blockchain industry also stands to be among…
Academics argue that Bitcoin could be subject to attack from quantum computers by 2027. There are plenty of ways to meet this challenge, but given recent experience how easy will the Bitcoin community find it to organise its response? A new paper from Aggarwal, Brennen, Lee et al. starts by underlining the strength of Bitcoin’s main…
Commercial transactions on the Internet and routine cyber security depend on the effectiveness of public key cryptography. Quantum computers will make existing standards obsolete. The impact of this starts now. The central technical pillar of online security is the use of secure cryptographic algorithms to encrypt data, passwords and identities, and so keep them safe…
