The nature of network services is drastically afecting the way the infrastructure is evolving. New demands require new capabilities, forcing the infrastructure to dynamically adapt to new scenarios. Novel network paradigms, such as Software-Defined Networking (SDN) and Network Functions Virtualization (NFV), have appeared to provide flexibility for network management and services. On the other hand, traditional cryptographic protocols rely on certain mathematical problems (e.g. integer factorization, discrete logarithms or elliptic curves) that are believed not to be efciently solvable using conventional computing. This assumption is being revisited because of quantum computing, which may put at risk the traditional schemes used for network security. Quantum Key Distribution (QKD) is a technique for providing synchronized sources of random and secure symmetric keys between two separated locations. Its security is based on the fundamental laws of quantum physics, according to which it is not possible to copy the quantum states transmitted between endpoints. Therefore, if implemented properly, QKD generated keys are immune against any algorithmic cryptanalysis. This work describes techniques to implement such new security layer in current and novel network architectures. Our work shows how QKD can be integrated in standard security protocols and network architectures for securing control and data planes, providing a whole quantum-safe network environment. This was demonstrated at the Madrid SDN-QKD network, comprising 3 remote nodes connected through standard optical devices in an operational environment and with the physical links among sites being shared between classical and quantum signals.
