'''Secure Communication based on Quantum Cryptography''' ('''SECOQC''') is a project that aims to develop [[quantum cryptography]] (see there for further details). The [[European Union]] decided in 2004 to invest 11 million [[Euro|EUR]] in the project as a way of circumventing [[espionage]] attempts by [[ECHELON]]. [[Christian Monyk]], the coordinator of SECOQC, said people and organizations in [[Austria]], [[Belgium]], the [[United Kingdom]], [[Canada]], the [[Czech Republic]], [[Denmark]], [[France]], [[Germany]], [[Italy]], [[Russia]], [[Sweden]], and [[Switzerland]] would participate in the project.

On October 8, 2008 SECOQC was launched in Vienna .<ref>[http://news.bbc.co.uk/1/hi/sci/tech/7661311.stm BBC]</ref><ref>[http://news.yahoo.com/s/afp/20081008/sc_afp/sciencequantumphysicsittelecomaustria Yahoo news]</ref>.

== Limitations of classical Quantum Cryptography ==

Line 10:

SECOQC network architecture can by divided by two parts. Trusted private network and quantum network consisted with QBBs(Quantum Back Bone). Private network is conventional network with end-nodes and a QBB. QBB provides quantum channel communication between QBBs. QBB is consisted with a number of QKD devices that are connected with other QKD devices in 1-to-1 connection.

From this, SECOQC can provide easier registration of new end-node in QKD network, and quick recovery from threatenings on quantum channel links.
