IXEurope and Swiss-based company trial quantum cryptography for increased security between IXDatacentres

IXEurope, one of Europe's fastest growing datacentre services companies, and Geneva, Switzerland based idQuantique SA, the quantum cryptography company, have agreed to set up a twin-datacentre pilot site using Quantum Cryptography. This technology encrypts the optical signals within inter-site dark fibre links and it is expected to be able to provide total optical data security between customers' IT installations when dual site solutions are deployed.

Announced at Orbit-iEX 2006 Solution Park in Zurich, the companies demonstrated the benefits of idQuantique's unbreakable encryption solution combined with IXEurope's sophisticated IXDatacentres to provide unconditional data confidentiality, integrity and availability.

“idQuantique's cryptographic appliance is ideal for encrypting transmissions over networks between locations, and combines ease of integration into existing networks and uncompromised security,” says Andy Castle, VP of IT Services at IXEurope. “The pilot between our IXDatacentres™ in Zurich will allow us to test reactions to this high level of security solution. Potential customers include financial services, pharmaceutical companies, government agencies and R&D companies, many of which are already using our IXDatacentres for their IT installations”.

The Vectis link encryptor is a hardware Quantum Cryptography appliance for point-to-point wire-speed optical link encryption. It combines QKD (Quantum Key Distribution) and an industry standard based encryption engine AES (Advanced Encryption Standard) in a stand-alone appliance. It allows secure communication between remote networks connected by an optical fiber up to a distance of 100 km.

Over the past 5 years optical fibre cables have replaced copper cables for almost all high bandwidth metropolitan area networks (MANs). Intercepting information transmitted over an optical fibre cable is however possible and this new technology provides an added level of protection to those whose data simply cannot be compromised.

The Achilles Heel of existing cryptography solutions is the key exchange process. While conventional key distribution techniques rely on public key cryptography or manual exchange, and therefore offer only limited security, the secrecy of keys distributed by quantum cryptography is guaranteed in an absolute fashion by quantum physics. Quantum Cryptography is a technology that exploits a fundamental principle of quantum physics - observation causes perturbation. Frequently exchanged cryptographic keys are continuously checked for photon disturbance which would be created by interception along a fibre connection.
