Problems solved by technology

[0009] First, due to ignoring the influence of the correlation between various key components in the system on the system operation results, the test process lacks systematicness, and the test results lack systematic analysis, so that the obtained test conclusions are often one-sided
[0010] The second is to greatly increase the number of repeated tests, wasting time and greatly increasing the cost of testing

Abstract

The invention belongs to the technical field of quantum private communication and provides a test and verification device for key apparatuses in a QKD (quantum key distribution) system. The device comprises a QKD system sender and a QKD system receiver, and the sender and the receiver are connected through an optical fiber. The device is characterized in that a key agreement module, a classical communication interface, a quantum optical system, a data display and man-machine interaction module and a data analysis module are arranged in each of the sender and receiver, and the data display and man-machine interaction modules are used for setting test parameters of each key apparatus, sending test data collected in the test process to the data analysis modules and displaying and outputting test results obtained by the data analysis module. The test data are calculated and analyzed through the data analysis modules to obtain correlation among the test parameters of the key apparatuses, and reliability and credibility of test conclusion are improved.

Description

technical field [0001] The invention belongs to the technical field of secure communication, and in particular relates to a test and verification device for key components in a QKD system. Background technique [0002] Quantum communication is a new interdisciplinary subject developed in the past two decades, and a new research field combining quantum theory and information theory. Recently, this subject has gradually moved from theory to experiment, and to practical development. Efficient and safe information transmission has attracted more and more attention. [0003] Physically, quantum communication can be understood as high-performance communication realized by using quantum effects under the physical limit. In informatics, we believe that quantum communication is the use of the basic principles of quantum mechanics (such as the principle of non-cloning of quantum states and the measurement collapse properties of quantum states, etc.) or the use of quantum system-speci...
