By combining quantum key distribution with conventional encryption an unprecedented level of security can be achieved.
Melbourne, Australia (PRWEB) October 20, 2010
Senetas Corporation Limited (ASX:SEN), Australia’s world-leading high speed network encryption company, announced today that its patented encryption technology had been deployed in The Netherlands as part of the country’s first commercial quantum cryptography demonstration.
In a collaboration between Senetas’ Swiss partner IDQuantique and Siemens IT Solutions and Services, the first commercial application of a quantum cryptography project in the Netherlands secures the data transfer via optical fiber connections - with high bandwidth and availability demands – between the data centers of the Siemens offices in The Hague and Zoetermeer.
In this project, the data transfer over the Siemens network is protected by a hybrid cryptography system, combining conventional and quantum techniques. Senetas provides the conventional cryptography, whereas Swiss IDQ supplies the quantum cryptography.
This innovative demo project for information security in principle runs until the end of the year. In August Siemens IT Solutions and Services had already announced that it would bring this type of data security to the Dutch market.
Quantum cryptography offers new opportunities for the electronic communication of confidential and sensitive information. The information is not only secured at the moment of communicating, but also over a longer period. By combining quantum key distribution with conventional encryption an unprecedented level of security can be achieved. In Switzerland this technology is currently being used for secured communication in the transfer of referendum results. In other countries, government agencies, patent offices and financial institutes use similar methods to exchange confidential and sensitive information.
In secured electronic communication the emitter uses a key to encrypt the message. The receiver uses the same key to retrieve the original message. To guarantee data security, it is essential that this key is safely exchanged between emitter and receiver. Quantum key distribution supports the key distribution security by continuously generating new key strings. As a result, an encryption application is constantly provided with new and secure key strings, which increases security.
The security of quantum key distribution is guaranteed because it is not based on mathematical assumptions, but on fundamental laws of physics relating to the behavior of matter and energy – quantum mechanics. This allows for detection of unauthorized persons during the key distribution. Unauthorized intervention can be detected not only when the key is manipulated, but also if someone is eavesdropping on the key exchange. In quantum key distribution, the keys are emitted as light particles or photons. Thanks to quantum-mechanical principles it is impossible to make a perfect copy of such a key. Also, photons can be measured only once, after which they change their state in a random manner. If the properties of the photons have changed during transfer, the legitimate users know that their key has been intercepted.
Senetas Corporation Limited (ASX Code: SEN) is an Australian ASX-listed public company and is the world’s leading developer and supplier of high speed network encryption hardware products. Its products are accredited to the highest international government security standards (FIPS and Common Criteria). Senetas is now represented in more than 40 countries and customers include Government, military and law enforcement agencies in Australia, USA, Middle East, Asia, and the EU, as well as leading financial institutions.
