| description | Quantum-key-distribution (QKD) networks are gaining importance and it has
become necessary to analyze the most appropriate methods for their
long-distance interconnection. In this paper, four different methods of
interconnecting remote QKD networks are proposed. The methods are used to link
three different QKD testbeds in Europe, located in Berlin, Madrid, and Poznan.
Although long-distance QKD links are only emulated, the used methods can serve
as a blueprint for a secure interconnection of distant QKD networks in the
future. Specifically, the presented approaches combine, in a transparent way,
different fiber and satellite physical media, as well as common standards of
key-delivery interfaces. The testbed interconnections are designed to increase
the security by utilizing multipath techniques and multiple hybridizations of
QKD and post quantum cryptography (PQC) algorithms. |
