摘要:
      传统量子保密通信系统实时生成的量子密钥量有限,难以适应电力生产调度、营销和管理信息化等业务数据不同的安全等级和通信特性需求,无法对各类电力业务数据实现精准数据保护。文中深入分析了各电力业务的数据资产重要度和数据传输指标需求,提出自适应电力业务属性的量子密钥更新频率计算方法、密钥补充策略和最优分配策略,并优化量子虚拟专用网络(VPN)的量子密钥控制流程,解决了传统量子VPN对各业务采用无差别量子密钥更新频率的不足。实验结果展示了所阐述方法可实现各电力业务精准数据保护的量子密钥最优分配自动化及智能化。该方法可构建基于量子密钥的精准安全数据保护机制。
Abstract:
      The amount of quantum keys generated in real time for traditional quantum security communication systems is limited. It is difficult to adapt to different security levels and communication characteristics of business data such as electricity production scheduling, marketing and management informatization. It is impossible to achieve accurate data protection for various types of power service data. The importance of power business data asset and the data transmission requirements are analyzed. Aiming at solving the lack of indiscriminate quantum key replenishment strategy for each business of traditional quantum virtual private network(VPN), the quantum key update frequency calculation method, key replenishment strategy and optimal allocation strategy model with adaptive power business attributes are proposed. The problem of the traditional quantum VPN adopting non-differential quantum key update frequency for each service is solved. Experimental results show that the method can realize the automatic and intelligent optimization of the quantum key distribution for the accurate data protection of various power services. A precise and secure data protection mechanism based on quantum key could be built by the proposed method.
