The first application of quantum encryption technology in large-scale international sports events in China
"The operation data of the field equipment is collected normally, and the message has been sent to the main station through quantum encryption." After quantum encryption, it was successfully sent to the Asian Games power security system, adding a super "password lock" to Hangzhou Shuzhi Asian Games power security system. This is also the first time that quantum technology has been applied to the power security of a large-scale international sports event in China.
With the approaching of the Hangzhou Asian Games, high-quality and high-standard promotion of the preparations for the Asian Games and the Asian Paralympic Games and the implementation of epidemic prevention and control work go hand in hand. The Asian Games have a long period of power protection and a wide range of coverage. Under the background of the epidemic, using high-tech means to avoid the gathering of power protection personnel during the Asian Games has become an important exploration topic in the preparations for power protection.
The quantum key generated by quantum encryption technology has the advantages of being unbreakable and uneavesdropping, and is a reliable communication password. State Grid Hangzhou Power Supply Company relies on the intelligent distribution network hybrid simulation laboratory. After several rounds of technical certification, testing and testing, it is finally determined to connect the quantum encryption terminal to the RTU (remote motor) in the computer room, so that the current collected by the remote motor, The power operation status data such as voltage and switching status are uploaded to the Asian Games Power Protection System through the quantum encryption tunnel. With the help of quantum key generation, distribution and communication negotiation mechanism, a quantum encryption security tunnel is built between the master station and power equipment, providing a strong security barrier for power equipment data reporting and instruction issuance.
State Grid Hangzhou Power Supply Company used quantum encryption technology in the Asian Games power protection work, which not only guaranteed the real-time nature of the power operation status data upload to the main station, but also improved the safety and reliability of the power information transmission process, making the venue-side data economical and efficient. , Safely transmitted to the power protection system, which more effectively reduces the human input in the process of power protection, thereby avoiding crowd gathering.
"In order to achieve intelligent, reliable and precise power protection for the Asian Games, we have built an emergency command and political power protection application system. How to ensure the safe and accurate upload of massive power grid data in 56 Asian Games venues has become an important test for the construction of an efficient command system for the Asian Games." Liu Weihao, deputy chief engineer and director of the Transportation Inspection Department of Hangzhou Power Supply Company, said, "Quantum encryption technology has become our primary choice for data encryption because of its non-eavesdropping, non-copying, and inability to measure. After the 'code lock' is encrypted, it will be sent to the power protection system, so that the security of Hangzhou Asian Games power grid will reach the international leading level."
It is reported that the State Grid Hangzhou Power Supply Company will achieve full access to quantum transmission in all Asian Games venues, accelerate the full coverage of quantum transformation of important distribution network switches in the Asian Games area, and expand the application scenarios of quantum encryption technology in the power system source, network, load and storage fields. Quantum locks escort the digital security of Asian Games.
