Hefei Liangzi City Network is expected to expand to four counties and cities

On the afternoon of September 6, 2022 National Cyber ​​Security Weekly Weekly Safety Sub -Forum was held in Hefei, Anhui. Focusing on how to further integrate classic information security and quantum security, promote cutting -edge technologies such as quantum technology as soon as possible, academician experts, industry representatives, etc. gathered together to talk about technology and collide the "spark" of collision ideas.

The first -time quantum safety related forum was held

Cyber ​​Security Week is the "top -level event" of national cybersecurity. The Internet Security Week has exerted the development advantage of Hefei in the field of quantum communication. Xu Hongxing, an academician of the Chinese Academy of Sciences and the dean of the School of Physics and Technology of Wuhan University, said that the protection of key information infrastructure is particularly important. At the moment when the "quantum hegemony" competitions are competitions, quantum information technology is related to the security of the security of the country. The first quantum confidential communication technology in quantum technology can be widely integrated with classic information security technology, serving government affairs, finance, energy, medical care, transportation and other industries, which has an important role in improving the national network security guarantee level.

Lu Chaoyang, a well -known youth quantum physicist, Professor of the University of Science and Technology of China and the executive dean of the Shanghai Research Institute of China University of Science and Technology, introduced the latest development of quantum computing and new changes in information security. Lu Chaoyang introduced that in recent years, three of the four major iconic events in the international quantum information field have been led by the city of Hefei. "I am very happy as practitioners and researchers."

Release the latest quantum security capacity base

At the forum, Anhui Provincial Department of Science and Technology, Hefei Science and Technology Bureau, High -tech Zone Management Committee, HKUST National Shield quantum quantum quantum, China Telecom quantum, Tianrongxin and other units jointly released the latest quantum safety capacity base.

"This is a platform built between the quantum confidential communication network and the user -end quantum business. Before this base is released, a business may be built. , Can improve the efficiency, scale and scalability of quantum network services. "Tong Jian Gang, an expert of China Telecom Research Institute, introduced that the base was created by the University of HKUST, a bridge connecting users and quantum confidential communication networks. , Bring together three major platforms: password management, identity authentication, and business control. Focus on the five key industries: digital governments, public security justice, disciplinary inspection and supervision, public safety, and finance, to provide quantum security services for a number of smart application scenarios.

Hefei Quantum City Network is expected to access the national quantum backbone network

Peng Chengzhi, a researcher at the University of Science and Technology of China and the chairman of the HKUST -CUHK quantum quantum quantum, introduced the world's largest, most widely covered, and most application quantum confidential communication city network- "Hefei Quantum City Network".

The network was officially launched in September 2021. It fully adopts independent controllable quantum communication equipment in the construction. It applies the industry's leading classic-quantum wave duplication technology to realize the symbol transmission of quantum, negotiation and business channels, and network networking. The plan is the world's leading. At present, 8 core nodes and 159 access nodes have been included. The quantum key distributes the total length of the network optical fiber of 1147 kilometers. It can provide quantum security access services for nearly 500 party and government agencies in the city and districts. Safety protection level. At present, Hefei Liangzi City Network has been launched to run unified government information processing platforms, big data platforms, public credit information sharing service platforms, and provincial financial departments to the Municipal Finance Bureau's budget integrated system. After the relocation, the business system runs smoothly, and the business system migration will be carried out in accordance with the actual needs of various committees and bureaus.

In the future, Hefei Quantum City Network is expected to continue to expand coverage until four counties and cities, and access the national quantum backbone network. The completion of Hefei Liangzi City Network further improves the new infrastructure of Hefei, providing strong infrastructure support for the city's information security guarantee. The construction of the network also helps the layout and development of the ecological chain of the quantum information industry in Hefei, and create an innovation -driven and the world's leading "quantum center".

Quantum safety and quantum city area network

The concept of quantum security comes from the new contradictions and new games of information security offensive and defensive caused by the development of quantum technology. It is an information security technology that can resist super computing threats such as quantum computing. The quantum confidential communication network is a "quantum key" network that produces and distributes security for both parties. This kind of key is based on the characteristics of indiscriminate and unspecity of quantum, which ensures the unshaps of the information, thereby ensuring the security of communication.

According to the coverage range, quantum confidential communication networks can be divided into different types. Quantum confidential communication backbone network (hereinafter referred to as the backbone network) realizes cross -provincial and cross -city connection; quantum confidential communication urban area network (hereinafter referred to as urban area network) is responsible for connection between different regions and industry institutions within the city; quantum confidential communication LAN network network (The following is referred to as the LAN) Implementing multiple terminal access in a unit or one place. The quantum city network backbone network, the lower part of the LAN/user area, has the requirements of the needs of medium link length, large business capacity, high scalability requirements, and complex network topology.
