A quantum security leap?

What is quantum security, what are the real world implications for the enterprise and is it really unbreakable? Davey Winder has been investigating...

The answer is a simple one, it seems. "Quantum Key Distribution (QKD) does not work well in practice" Axelle Apvrille, senior researcher at Fortinet's Europe, Middle East and Africa (EMEA) Threat Response Team told IT PRO, adding "its limited as the network cannot be more than 200km long and its expensive as it requires optical fibre and dedicated hardware equipment and networks".

In fact, she is so convinced of the limitations of quantum cryptography that she says "I don't think QKD will ever make it to the enterprise. And if I turn out to be wrong, it shouldn't be in the next ten years".

Dave Waterson, chief executive at SentryBay, suggests that right now there is no real need for quantum security anyway, telling us "public/private key encryption is still sufficiently secure" and that until the advent of real-world quantum computers" RSA encryption is still secure and reliable.
