Security boffins build broadband speed quantum crypto network

Abstract:
UK-based boffins have set a new record for quantum key distribution in a move that paves the way towards faster high security communication networks for banks and governments.

Toshiba Research Europe Cambridge hit a sustained secure bit rate exceeding 1 Mbps over 50 km of fibre for the first time, around 100-1000 times faster than anything previously demonstrated for this length of cable.

Quantum key exchange allows the everyday use of "one-time pad" encryption which, when properly implemented, offers absolute security. Assumptions about the security of the technique are not dependant on the computing power of an adversary because security of the system relies on quantum effects that mean it is not possible to eavesdrop of conversations without altering the data streams. Such alterations would be detected as errors, immediately alerting the recipient who can then take action to ‘lock down' the data stream.
