Physicists at the University of Strathclyde and Heriot-Watt University have developed a new way of verifying electronic transactions using light.
Their approach uses photons to create digital signatures, the security of which are based on the laws of quantum physics. The team includes CNQO’s Dr John Jeffers. Their advance could help tackle the huge burden of e-crime, which is estimated to cost £205 million in the UK retail sector alone. Their work, recently published in the journal Nature Communications, was reported on the BBC news website. More information can be found on the following pages:
