随着电网规模的壮大和系统复杂性的增加,电网对电力通信网业务传输的安全性提出更严格的要求。电力系统二次防护体系中,传统加密装置使用对称加密算法对通信数据进行加、解密处理。量子密钥拥有极高的安全性,将量子密钥运用于电力通信网加密装置能够极大地提高业务传输的安全性。现有量子密钥分发设备产生的密钥资源有限,难以保证全部电力业务数据一次一密的加密传输。因此,需要通过建立合适的业务重要度评价方法,优先保证重要业务的保密传输。提出一种量子通信背景下,基于各个业务的传输性能指标建立相对重要度矩阵的方法,获得电力通信网业务重要度,以开展后续的量子密钥应用策略研究。
With the expansion of the power grid and the increase of the complexity of the power system
the power grid has more stringent requirements for the security of the services transmission. In the secondary protection system of power systems
traditional encryption devices use symmetric encryption algorithms to add and decrypt communication data. Quantum keys have extremely high security. Applying the quantum keys to the power communication network encryption devices can greatly improve the security of service transmission. The quantum key resources generated by the existing quantum key distribution devices is limited
and it is difficult to ensure that all power services data are encrypted and transmitted. Therefore
it is necessary to prioritize the confidential transmission of important services by establishing appropriate evaluation methods for services importance. A relative importance matrix based on the transmission performance indicators of each service was built under the background of quantum communication
so as to obtain the importance of the power communication network business
and to carry out subsequent quantum key application strategy research.
