In this paper we present the implementation of first two stages of an agent-oriented KQD for Wi-Fi. At present, the first two stages of B92 (or BB84) protocol has been implemented in C++ language on Linux platform. The KQD can handle multiuser as it benefits from an agent-oriented mechanism. This caused a heavy overhead as the program consumes considerable amount of time during bit comparisons etc when doing file processing. To avoid this inefficiency, a STL list structure has been implemented to hold the index file data. Due to this modification, most of the computations and bit comparisons are done in-memory. This has resulted in improving the efficiency by about 60%. With this set up, the program can be operated by setting different values to suit any requirements. One such parameter is the QBER, where this value is used to calculate the error rate of the quantum transmission. QBER of the quantum transmissions could be impacted by various issues (described earlier) causing it to vary per each transmission. Therefore by having the QBER as a configurable parameter, this software can be used to run even for simulation purposes by setting different values.
