Description

Technical Field

[0001] The present invention relates to the field of security protection technology, and in particular to a laser security protection system based on quantum encryption technology. Background Art

[0002] Quantum encryption technology, as an encryption technology based on the principles of quantum mechanics, has the characteristics of high security and anti-eavesdropping, and fundamentally solves the problem of crackability in traditional cryptography. In the future information security field, quantum cryptography is expected to become an important encryption technology, providing a higher level of protection for information transmission. Laser is also a laser. The laser intensity, wavelength and other data collected by the sensor need to be transmitted to the control center for analysis and processing. The use of quantum encryption technology can ensure the confidentiality and integrity of these data transmissions and prevent data from being stolen or tampered with.

[0003] Currently, laser safety protection systems lack high-level security mechanisms in data transmission and processing, making it difficult to effectively respond to increasingly complex network threats, and are unable to ensure the secure transmission and processing of system data, as well as comprehensively monitor laser-related conditions and respond effectively in emergencies.

[0023] Working principle: First, the quantum key generation and distribution module starts working. The quantum state preparation unit generates quantum states with specific quantum properties, laying the foundation for key generation. Then, the quantum measurement unit constructs highly secure quantum keys based on these quantum states. Then, the key distribution control unit accurately distributes the generated quantum keys to other modules in the system, thereby providing top-level security for subsequent data transmission and processing, ensuring the confidentiality and integrity of system data.

[0024] With a secure key foundation, the laser light source monitoring module begins to play a role. The power detection unit obtains the power data of the laser light source in real time, and the wavelength detection unit synchronously detects the wavelength of the laser. These data are transmitted to the stability analysis unit, which comprehensively analyzes the changes in power and wavelength, so as to accurately judge the stability of the light source. During the laser transmission process, the laser transmission path detection module intervenes. The loss detection unit first measures the energy loss of the laser during transmission. The scattering detection unit then detects whether there are interferences that cause laser scattering. The refraction anomaly detection unit constantly monitors the refraction anomaly in laser transmission. Once any anomaly is found, the relevant data will be quickly transmitted to the subsequent modules for processing;

[0025] At the same time, the environmental perception module is also operating continuously. The temperature sensor unit senses the ambient temperature in real time, the humidity sensor unit accurately measures the ambient humidity, and the electromagnetic field detection unit closely detects the surrounding electromagnetic field strength and changes. These environmental data provide important references for the comprehensive evaluation of the system. Then, the data encryption and decryption module starts to work. The encryption algorithm execution unit uses the received quantum key to encrypt the laser-related data, so that the data is in a highly secure state during transmission and storage. When the data needs to be used, the decryption algorithm execution unit can restore the encrypted data to the original data, and the key storage unit always safely stores the quantum key.

[0026] Next, the risk assessment module operates. The parameter analysis unit deeply analyzes the laser parameters and environmental data collected by the previous modules. The risk calculation unit calculates the specific value or level of the risk degree based on these analysis results. The threshold setting unit sets a reasonable risk threshold in advance. Once the calculated risk value exceeds the threshold, an emergency response will be triggered.

[0027] The power cut-off control unit in the emergency response module will quickly cut off the power supply of the laser source, and the protective device activation unit will immediately activate the protective barrier or shading device to maximize the safety of personnel and equipment. During the entire system operation, the log protocol module is always recording, the log data acquisition unit comprehensively collects various operations and event data in the system operation, the storage management unit properly preserves these data, the audit analysis unit carefully reviews and deeply analyzes them, and the interface unit ensures the connection and data interaction between the system and external devices. At the same time, the connection and data interaction with external devices will be recorded in the log data acquisition unit, through the processing and analysis of these log data.

[0028] The present invention provides a laser security protection system based on quantum encryption technology. It has the following beneficial effects:

[0029] 1. The present invention adopts quantum key generation and distribution technology to provide top-level security for system data transmission and processing. At the same time, multiple modules work together to comprehensively monitor the laser light source, transmission path and environmental conditions. In an emergency, the laser source can be quickly cut off and the protective device can be activated. The protective barrier or sunshade can effectively block the light to ensure the safety of personnel and equipment and avoid damage caused by laser lasers.

[0030] 2. The present invention acquires the key parameters of laser power and wavelength, as well as the temperature and humidity information of the environment in real time, deeply analyzes and calculates the degree of risk, and sets a reasonable risk threshold in advance, so that the system can detect potential problems in time, make preventive preparations, effectively avoid risks, ensure that the system runs stably in a safe and reliable state, and provide reliable laser safety protection for various application scenarios.

[0031] 3. The present invention records operation operations, events and data completely through the system, covering the connection between the system and external devices and data interaction. This not only facilitates subsequent detailed audit analysis and troubleshooting, but also helps to summarize experience and discover optimization space for the system, thereby improving the level of maintenance and management, and providing subsequent guarantees for the system's subsequent continuous stable operation and performance improvement.
