Why quantum computing is a security threat and how to defend against it [Q&A]

Quantum computing offers incredible computing power and is set to transform many areas such as research. However, it also represents a threat to current security systems as cracking passwords and encryption keys becomes much easier. So quantum is a security threat, but is there a solution to making systems safer? We spoke to David Williams, CEO of symmetric encryption specialist Arqit, to find out. BN: Why are current encryption techniques no longer adequate? DW: First, public key cryptography was not designed for a hyper-connected world, it wasn't designed for an Internet of Things, it's unsuitable for the nature of the… [Continue Reading]
