Latest Patents

Shiqin Liu holds a patent for a "Key distribution method and system based on synchronized broadband physical random sources." This patent describes a method that involves generating an optical signal using a driving semiconductor laser. The optical signal is then passed through a phase modulator driven by a random signal, which is subsequently divided into two identical paths. These paths are injected into slave semiconductor lasers at both communication parties, Alice and Bob, to generate initial synchronized signals. The process continues with phase-modulating optical signals generated by continuous-wave light sources, leading to the creation of high-speed synchronized keys through a post-processing method.
