[ Watch the Video: Keeping Secrets in a World of Spies and Mistrust ] Peter Suciu for redOrbit.com - Your Universe Online Is it really a secret if researchers share it? In the March 27 issue of Nature, the weekly international journal of science, researchers Artur Ekert and Renato Renner revealed what physics can tell us about keeping our secrets secret. This comes after high profile revelation that the National Security Agency (NSA) had been spying on emails, phone calls and other...

Cryptography Scheme Secured By Quantum Physics

Centre for Quantum Technologies The way we secure digital transactions could soon change. An international team has demonstrated a form of quantum cryptography that can protect people doing business with others they may not know or trust – a situation encountered often on the internet and in everyday life, for example at a bank's ATM. "Having quantum cryptography to hand is a realistic prospect, I think. I expect that quantum technologies will gradually become integrated with existing...

Quantum cryptography is the ultimate secret message service. Now new research, to be presented at the 2012 AAAS Annual Meeting, shows it can counter even the ultimate paranoid scenario: when the equipment or even the operator is in the control of a malicious power. Until now, quantum cryptography protocols have always assumed that an adversary would not have access to information about any choices that are made during the process of encryption. "We are challenging this assumption," says...
