Secure Communication based on Quantum Cryptography

The European Union decided in 2004 to invest 11 million 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.

If a node wants to participate into the QKD network, it will cause some issues like constructing quantum communication line.

Each QBB enables quantum channel communication with another QBB and consists of a number of QKD devices that are connected with other QKD devices over one-to-one connections.

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