Description

Technical Field

[0001] This invention relates to meteorological data transmission, and more specifically to a meteorological data transmission method based on quantum key encryption. Background Technology

[0002] Meteorological data is the core foundational data for meteorological monitoring, disaster early warning, climate analysis, and disaster prevention and mitigation decision-making. It encompasses multi-source heterogeneous information from ground observations, upper-air sounding, and meteorological satellite remote sensing. The real-time performance and transmission security of this data directly impact the stable operation of meteorological services. Currently, meteorological data is mostly transmitted across regions via public communication links, dedicated wireless channels, and satellite channels. Traditional encrypted transmission methods suffer from security vulnerabilities such as easily cracked keys, channel eavesdropping, and data tampering, making it difficult to meet the high-security transmission requirements of classified meteorological data and critical detection information.

[0003] Quantum key encryption possesses technological advantages such as one-time pad, instant detection of eavesdropping, and theoretical unconditional security, effectively compensating for the security shortcomings of traditional encryption methods. However, existing quantum key encrypted meteorological data transmission schemes have significant flaws. Unreasonable multi-link transmission bandwidth allocation and disordered quantum key distribution time slot allocation easily lead to problems such as link load imbalance and key resource waste. Simultaneously, fixed encryption computing power configurations and lack of equipment power consumption control easily result in key resource waste and link load imbalance, thereby increasing transmission latency and exacerbating equipment energy consumption. Furthermore, in complex meteorological scenarios such as extreme strong convection, heavy rain, and strong electromagnetic interference, transmission stability and anti-interference capabilities are significantly reduced.

[0004] Traditional resource scheduling optimization algorithms often employ fixed search mechanisms, exhibiting poor balancing between global exploration and local exploitation. They are prone to getting trapped in local optima and struggle to coordinate optimization of multiple metrics such as transmission latency, link balance, quantum key utilization, and encryption energy consumption. Furthermore, they cannot dynamically adapt to complex meteorological environments. Therefore, there is an urgent need to design a quantum key encryption-based meteorological data transmission method that combines intelligent optimization algorithms to achieve adaptive scheduling of transmission resources, balancing the security, real-time performance, and operational stability of meteorological data transmission. Summary of the Invention
