Secure communication system based on silicon photon chaos source

The invention provides a secure communication system based on a silicon photon chaos source. The secure communication system comprises a chaos driving module, a response system, a signal input moduleand a signal receiving module; the chaos driving module generates one main chaos signal and injects into the response system; meanwhile, the response system generates a plurality of subordinated chaossignals by own, and injects different intensities of the main chaos signals into the response system till the plurality of subordinated chaos signals reach chaos synchronization; and the signal inputmodule and the signal receiving module are respectively and electrically connected with the response system. The secure communication system provided by the invention has the following beneficial effects: since the chaos source generated by a silicon photon in a photo crystal microcavity is adopted, the integration of a chaos generation device is implemented; the stability of the chaos source isgood, so the secure communic
