The FPGA Implementation of Quantum Key Distribution Based on BB84 protocol
Huifang Li, Minghui Zhang, Kaibin Wang · 2016
A new QKD implementation scheme of BB84 protocol is introduced based on FPGA.Firstly, the overall design method and the functional division are described in detail.Then, the logic design of the sub-module are significantly studied, including random data module, laser source drive module, error correcting module, receiver/transmitter interface module, extracting original key module and error rate estimation module.Finally, the partial simulation results are given to verify the correctness of the design function.The set-up advantage is the small size, high bitrates, flexible configuration, and convenient algorithm update.
