Abstract. Quantum key distribution protocol is a hot spot of research in the information security, so, lots of Quantum key distribution protocol appeared. Every quantum protocol needs to be confirmed whether it is feasible and safe, if all those quantum protocols use physics experiment to verify, it is very complex and expensive. So, we introduce the platform, a functional platform for quantum key distribution protocols simulation. This platform introduces communication receiver, sender, establishment and protocol selection etc and it was designed on .NET IDE, the main programming language is C#. We simulated the existing BB84 protocol on this platform, and got the simulation results which were completely tallied with theoretic results
