Description

Technical Field

[0001] The present invention relates to the technical field of quantum encryption communication, and in particular to a quantum secure communication networking based on a MESH network. Background Art

[0002] Mesh Networking technology is an advanced wireless network architecture that achieves efficient data transmission and self-organizing network expansion through the cooperation between distributed network nodes. The core of Mesh Networking technology lies in its distributed structure and dynamic routing algorithm.

[0003] With the rapid advancement of radio and information technology, on-site rapid deployment and emergency response strategies under information conditions are also evolving. Traditional wireless communication equipment often has insufficient signal coverage or even blind spots. Although the quantum secure audio and video command platform based on the traditional operator network can ensure absolute security during data transmission, its dependence on the operator's network speed still has the following limitations: (1) When encountering areas with poor signal coverage or no signal, over-reliance on the operator network causes the efficiency of the quantum secure audio and video command platform to be greatly reduced, making it seem unable to cope with the situation.

[0004] (2) Traditional systems require the construction of numerous base stations throughout the city, which must communicate with the command center via optical fiber. This not only requires the rental of optical fiber and other facilities, resulting in high project complexity, long cycles, and high costs, but also relatively high difficulty in network maintenance. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a quantum secure communication network based on a MESH network to solve the problems raised in the above-mentioned background technology. The present invention opens up the communication link of the last mile and avoids the situation where information transmission cannot be carried out due to areas with poor signal coverage or even no signal coverage. The security is significantly improved, and the communication network can be quickly established without relying on any wired communication network equipment.

[0006] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a quantum secure communication network based on a MESH network, which is composed of a quantum secure audio and video command platform and a MESH self-organizing network device. MESH self-organizing network devices are arranged at multiple nodes, and all nodes are interconnected. The network discovery technology is used to realize the discovery of new nodes and neighbor nodes in the mesh network and the establishment of corresponding information lists. Each relay node will select the next optimal node for forwarding according to its adjacency table until the data packet reaches the destination. The mesh network manages the forwarding of data packets through a dynamic routing protocol. If the source node makes the coverage in the area without blind spots, the command node can be set at any position.

[0007] Furthermore, each node maintains an adjacency table to record information about other nodes connected to it, which can help the node quickly select the nearest neighbor for communication; the node interconnection mode includes "one hop" or "multi-hop".

[0008] Furthermore, if the source node and the destination node are directly connected in the adjacency table, the data packet can be sent directly to the destination node.

[0009] Furthermore, if the destination node is not in the adjacency range, the source node will look up other nodes in the adjacency table and forward the data packet to the destination node through them step by step.

[0010] Furthermore, the dynamic routing protocol is used to ensure that data packets can be forwarded between nodes through the optimal path regardless of whether it is a "one-hop" or "multi-hop" situation.

[0011] Furthermore, it also includes the use of Mesh wireless LAN communication between the terminal and the platform, and the use of quantum encryption to transmit audio and video streams. The platform does not perform encryption and decryption operations on the storage and forwarding of audio and video data.

[0012] Furthermore, there are multiple nodes in the communication networking system, and the node status is completely equal, the topology structure between nodes can be changed at will, and the MESH network has no central control node; each node will dynamically evaluate its connection status based on the signal strength and connection quality with the adjacent nodes.

[0013] Furthermore, each node has routing functions and can act as a sender and receiver of data. When the connection quality decreases, the node can choose other better adjacent nodes to communicate, thereby changing the network topology.

[0014] Furthermore, if a node fails or loses connection, other nodes maintain network connectivity by recalculating routes, and at the same time, MESH networks usually use dynamic routing protocols, which are used to automatically calculate the optimal path based on the real-time status of the network.

[0015] Furthermore, it also includes a quantum security cryptographic service platform, which is used to provide quantum cryptographic security capabilities, including a quantum security service mobile engine, a quantum random number generator, a key system exchange cipher machine, and a quantum key injection module.

[0016] Beneficial effects of the present invention: The quantum secure communication network based on the MESH network embeds a quantum secure TF card in the terminal device through the cryptographic service platform and performs a small amount of key updates. It can complete the equipment upgrade at a low cost and thus realize quantum secure communication.

[0017] The quantum secure communication network based on MESH network has higher security, and the integration of quantum communication technology significantly improves the security level of data transmission.

[0018] The quantum secure communication network based on the MESH network will not be disturbed or affected by the network conditions. It can quickly establish a communication network at any time and any place without relying on any wired communication network equipment (such as optical fiber, etc.), and can open up the last mile of the communication link, avoiding the situation where information transmission cannot be carried out due to areas with poor or even no signal coverage. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 This is a structural block diagram of a quantum secure communication network based on a MESH network in the present invention. DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] See also Figure 1The present invention provides the following technical solutions: a quantum secure communication network based on a MESH network. In this embodiment, the MESH self-organizing network adopts a new wireless IP mesh network design concept to realize a fully wireless "multi-hop" broadband self-organizing network in a certain area. There are multiple nodes in the system, and the node status is completely equal. The topology between nodes can be changed at will. The MESH network has no central control node. Each node has a routing function and can be used as a sender and receiver of data. This decentralized architecture allows each node to communicate with other nodes independently, increasing the flexibility of the network. Each node will dynamically evaluate its connection status based on the signal strength and connection quality with the adjacent nodes. When the connection quality decreases, the node can select other better adjacent nodes for communication, thereby changing the network topology. The system can quickly establish a communication network at any time and any place without relying on any wired communication network equipment (such as optical fiber, etc.), because the MESH network has no central control node, each node can be used as a sender and receiver of data and has a routing function. This structure has a high fault tolerance. If a node fails or loses connection, other nodes can maintain the connectivity of the network by recalculating the route. At the same time, MESH networks usually use dynamic routing protocols (such as AODV, OLSR, etc.), which can automatically calculate the optimal path according to the real-time status of the network. This dynamicity allows the network to quickly adapt to the addition or departure of nodes, as well as changes between nodes, and quickly establish a communication network. When all devices are powered on, they can automatically form a multi-hop transmission network to communicate with each other, and the device operation is simple and easy to understand. All nodes in the system support multi-hop relay (relay) communication, which is suitable for a variety of terrains and applications. Relay nodes can be relied on to extend coverage, realize relay communication, and ensure that there are no blind spots in the coverage of emergency areas.

[0022] This technical solution embeds a quantum security TF card in the terminal device through the cryptographic service platform and performs a small amount of key updates, which can complete the equipment upgrade at a low cost and thus realize quantum secure communication.

[0023] This embodiment also provides a quantum secure communication networking technology based on MESH network.

[0024] It consists of a quantum secure audio and video command platform and MESH self-organizing network devices. MESH self-organizing network devices are arranged at multiple nodes, and all nodes are interconnected through "one hop" or "multi-hop". First, the network discovery technology is used to realize the discovery of new nodes and neighbor nodes in the mesh network and establish the corresponding information list. Each node maintains an adjacency table to record the information of other nodes connected to itself, which can help the node quickly select the nearest neighbor for communication. If the source node and the target node are directly connected in the adjacency table, the data packet can be sent directly to the target node. If the target node is not within the adjacency range, the source node will find other nodes (relay nodes) in the adjacency table and forward the data packet to the target node through them step by step. Each relay node will select the next optimal node for forwarding according to its adjacency table until the data packet reaches the destination. Mesh networking manages the forwarding of data packets through dynamic routing protocols, which ensure that data packets can be forwarded through the optimal path between nodes, whether it is "one hop" or "multiple hops". If the source node makes the coverage in the area without blind spots, the command node can be set at any location. Mesh wireless LAN communication is used between the terminal and the platform, and quantum encryption is used to transmit audio and video streams. The platform does not perform encryption and decryption operations on the storage and forwarding of audio and video data. This technical solution is not afraid of network influence. It can quickly establish a communication network at any time and any place without relying on any wired communication network equipment (such as optical fiber, etc.). In addition, security is significantly improved. The integration of quantum communication technology has significantly improved the security level of data transmission.

It can transmit the front video back to the command center or the leader's mobile terminal device in real time through 4G law enforcement recorders, 4G emergency control balls (car-mounted), and drones. It can also be connected to other devices such as designated fixed monitoring through national standards or private protocols to form a three-dimensional mobile command network.

[0026] The quantum security service platform is the infrastructure that provides quantum cryptographic security capabilities, including a quantum security service mobile engine, a quantum random number generator, a key system exchange cipher machine, and a quantum key injection module.

[0027] MESH self-organizing network devices are divided into MESH self-organizing network backpacks and MESH self-organizing network handheld devices. MESH self-organizing network devices are arranged at multiple nodes. All nodes are interconnected through "one hop" or "multi-hop" methods, so that there are no blind spots in the coverage area, and the command node can be set at any location.

[0028] The mobile communication equipment of the audio and video command platform includes control balls, walkie-talkies, and law enforcement recorders, which digitally record the dynamic and static on-site conditions during the law enforcement process, synchronize them, and transmit them to the command platform after being encrypted with symmetric keys in secure media.

[0029] The secure medium is pre-filled with keys through the quantum security service platform, and is bound to the audio and video command terminal through the hardware feature code to obtain the session key.

[0030] Ⅰ. As shown in the topology diagram, the terminal and the platform use Mesh wireless LAN communication, and quantum encryption is used to transmit audio and video streams. The platform does not perform encryption and decryption operations on the storage and forwarding of audio and video data.

[0031] Ⅱ. MESH self-organizing network can achieve the same communication capability as the public network mode in the environment without operator network and direct power supply. Walkie-talkies, recorders, and mobile terminal products such as control balls can form integrated communication with the public network and self-organizing network on the same platform.

[0032] III. Mobile terminals using quantum secure symmetric keys have the characteristics of high communication security, controllable keys, terminal anti-loss, and high cost performance.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
