QKD keys secured classical communication tunnel

Resource file: 
Characteristics of QKD keys secured communication tunnel as an application transferring any kind of classical information within standard communication protocols.

Specification of a QKD tunnel which uses the Q3P structure of opensource AIT QKD Software mechanisms such as authentication, synchronization, and key expansion mechanism. Tunnel application which uses generated, shared and secured symmetric keys gives possibility to encrypt any classical communications similarly as VPN tunnels. In case of QKD tunnel the security is fully guaranteed due to use of OTP encryption cipher.
