Super-fast broadband services available across the globe could become more secure in the future, it has been reported.
New Scientist has revealed that a team of researchers at Toshiba Research Europe have developed a program which allows encrypted data to be sent through a high-speed network.
Based on quantum mechanics, the system sees a secret key sent from the sender to the recipient which will change if it subjected to an attack.
"Unfortunately, optical fibre can only transmit light over long distances when it is of a certain wavelength," the publication outlined.
"Individual photons of that wavelength are difficult to detect, but Toshiba has now developed a detector that can pick them up."
Technology expert Peter Cochrane recently claimed the UK is well behind other countries in terms of fibre-optic broadband services.
He called on the government to "grasp the nettle" and improve the speed of connections available to homes and businesses.
