ABSTRACT: We present a fully operable security gateway prototype, integrating quantum key distribution and realised as a system-on-chip. It is implemented on a field-programmable gate array and provides a virtual private network with low latency and gigabit throughput. The seamless hard- and software integration of a quantum key distribution layer enables high key-update rates for the encryption modules. Hence, the amount of data encrypted with one session key can be significantly decreased. We realise a highly modular architecture and make extensive use of software/hardware partitioning. This work is the first approach towards application of a new key distribution technology in dedicated security processors. In particular, it elaborates requirements for the integration of quantum key distribution on a chip level.
