Embodiment approach

[0071] As an implementation manner, the device further includes an SD card installation module; the SD card installation module is used for inserting an SD card storing a startup file or an update file.

[0072] In practical applications, first install the PetaLinux operating system in the device; then build the randomness test function, the process of building the randomness test function is as follows:

[0073] 1) Configure the cross-compilation environment so that the generated files can be used normally under the PetaLinux operating system.

[0074] 2) Create an empty project, and copy the hdf file generated in the hardware to the new project. Create a self-starting project using install as a template.

[0075] 3) Configure the project according to the system's option prompts and requirements.

[0076] 4) After the configuration file is generated, open the configuration file in the background and change the corresponding configuration so that it can cooperate well with the...

Abstract

One or more embodiments of this specification provide a quantum key randomness detection device, which includes a sequentially connected data processing module, a data transmission module, a data verification module, a data conversion module, and respectively connected to the data processing module, The instruction control and status monitoring module connected to the data transmission module, the data verification module, and the data conversion module; the quantum key randomness detection device receives the key data of the remote QKD device and the local QKD device, and then After passing through the data conversion module, data inspection module and data transmission module to the data processing module in turn, the data processing module detects the key data of the remote QKD device and the local QKD device, realizing the general detection of the quantum secret communication system.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of communications, and in particular to a quantum key randomness detection device. Background technique [0002] At present, there is a lack of third-party quantum security communication system performance index test instruments in the market. At this stage, the key index parameters of the quantum security communication system can only be obtained from the manufacturer's equipment network management or host computer software, and there is a lack of relevant testing equipment. [0003] Therefore, there is an urgent need for a general test platform suitable for quantum secure communication systems. Contents of the invention [0004] In view of this, the purpose of one or more embodiments of this specification is to propose a quantum key randomness detection device to solve the problem that it is impossible to perform universal testing on quantum secure communication systems. ...
