Abstract [en]

This thesis covers the basics of cryptography, both classical and the newer quantum-based approches. Further, it details an implementation of a BB84-based quantum key distribution system currently under construction, focusing on the controlling hardware and FPGA-based software. The overarching goal is to create a system impervious to currently known attacks on such systems. The system is currently running at 100 Mbit/s, though the goal is to double this as the design nears its completion. The system currently chooses encoding base, bit value and whether a state is a socalled decoy state. However, the modulator for bit encoding is not yet operational. Output for decoy state generation, however, is fully functional. Finally, the thesis describes what steps are necessary to reach a complete BB84-based quantum key distribution system implementing decoy states.
