摘要
针对电力系统的业务安全性需求,提出了一种基于密钥自演化的量子密钥分配方法。通过量子信道中传送在通信中产生的较短长度的随机量进行收发双方同步的密钥自演化,取代每次更新必须进行重新协商后再收发全新完整密钥的传统更新方式。这种方法能够在保证量子加密高安全性的同时克服量子密钥生成速率低的局限,提高量子密钥分配的密钥使用效率,使得量子密钥的实际使用能够满足要求。
In view of the business security requirements of power systems,a quantum key distribution method based on key self-evolution is proposed. The self-evolving key synchronization is performed by transmitting the shorter-length random amount generated in the communication in the quantum channel, instead of the traditional updating method in which the renegotiation must be performed after each update and the new complete key is received and transmitted. This method can overcome the limitation of low quantum key generation rate while ensuring the high security of quantum encryption,improve the key usage efficiency of quantum key distribution,and make the actual use of quantum keys meet the requirements.
