Embodiment 1

[0043] The system is powered on for hardware self-inspection. After the self-inspection is completed, data communication training is performed between the first SFP optical module A3 and the second SFP optical module B3. After the training is normal, the interaction of signaling and data services can be performed.

[0044] The first SFP optical module A3, the second SFP optical module B3, and the first SMA connector A6 and the second SMA connector B6 partly conduct cooperative training, so as to ensure that the password can be generated normally.

[0045] The polarization controllers SA6 and SB6 combined with the polarization data processors SA7 and SB7 start to adjust the polarization state of the optical fiber of the quantum secret channel through the polarization actuator, making it suitable for quantum channel work. Then A generates the initial password (SA12) according to the Seed of the pseudo-random password issued by the high-level; the password is encoded into data sui...

The quantum secret communication system controller comprises a first FPGA (Field Programmable Gate Array) chip, a first clock processing unit, a first SFP optical module, a first program storage unit, a first I / O interface, a first SMA connector, a first program encryption chip, a first LED (Light-Emitting Diode), a first USB (Universal Serial Bus) chip, a first RS232 chip, a first password generation control button, a second FPGA chip, a second clock processing unit, a second SFP optical module, a second program storage unit, a second I / O interface, a second SMA connector, a second program encryption chip, a second LED, a second USB chip and a second RS232 chip, wherein the first SFP optical module is connected with the second SFP optical module through an optical fiber; and the first SMA connector is connected with the second SMA connector through a coaxial cable. The invention provides a control and algorithm processing device for generating passwords in quantum secret communication. In the device, an FPGA is taken as a controller.

Description

technical field [0001] The invention relates to a quantum security communication system controller, which belongs to the field of security communication. Background technique [0002] Quantum secure communication utilizes the quantum characteristics of its information carrier—single photon, to achieve absolute security of communication, and plays an important role in industries such as national defense, politics, and finance where information security is paramount. But the current technology basically uses computers to generate quantum cryptography. [0003] At present, FPGA has not been used as a controller in quantum secure communication, and there are no independent patents or published papers. [0004] CN201010114280.0 "Quantum Security Phone" discloses an FPGA-controlled quantum security phone, but it is limited to the system composition, optical part composition and system workflow, and does not disclose the specific composition and working principle of the FPGA contr...
