Description

Technical Field

[0001] This invention belongs to the field of next-generation information technology and quantum encrypted communication technology, and particularly relates to a method and system for secure transmission of gas data based on quantum encrypted communication. Background Technology

[0002] With the widespread application of quantum encryption technology in fields such as industrial production, transmission of critical information, and confidentiality, its security performance has been widely recognized by the industry. In scenarios such as the secure transmission of gas data, critical gas detection data and control information have certain requirements for data security and confidentiality. The accelerated digital transformation of the energy industry is also driving the gas sector to continuously advance its intelligent construction. With the continuous improvement of computing power, especially the development of quantum computing technology, the security of traditional encryption technologies faces severe challenges. Quantum computers can crack traditional encryption algorithms in a short time. If used to attack the information systems of the gas industry, it could lead to serious consequences such as gas data leakage and the forgery of facility control commands.

[0003] Generally speaking, the core of quantum encrypted communication is based on the fundamental principles of quantum mechanics. Its fundamental difference from traditional encryption technologies lies in the fact that key generation and distribution are physical processes rather than mathematical operations. Quantum key distribution devices establish a shared random key sequence between communicating parties by preparing, transmitting, and measuring quantum states. Because the measurement of quantum states leads to irreversible collapse, any attempt by a third party to intercept and read quantum information will inevitably introduce detectable disturbances. This characteristic provides a physically based security guarantee for key transmission. However, practically deployed quantum channels often face challenges from fiber loss, environmental noise, and equipment imperfections. Bit error rate control and channel stability become key bottlenecks restricting the practical application of the system. Therefore, when embedding quantum encryption technology into industrial data transmission scenarios, it is essential to construct a channel architecture capable of differentiating between different security levels to balance the contradiction between security strength and transmission efficiency.

[0004] In the data security transmission scenarios of the gas industry, the application value of quantum encrypted communication lies in improving and perfecting the existing protection system. Gas system operation data encompasses various sensitive contents such as pipeline pressure monitoring, user gas metering, and transaction settlement information. Traditional encryption methods rely on algorithm complexity and key management standards, and their security continuously declines with increasing computing power. The introduction of quantum encrypted terminals does not replace existing communication infrastructure, but rather strengthens encryption capabilities at critical links. For example, the vulnerable quantum channel responsible for key negotiation is functionally separated from the strongly encrypted channel carrying encrypted business data. A secure interoperability mechanism is established between the channels, allowing key update status to be fed back to the business data transmission layer in real time, and attack interference detection information can also be simultaneously incorporated into the communication negotiation process. Under this architecture, the transmission process of gas data is no longer limited to passive encryption protection, but forms a complete protection chain including security monitoring, identity authentication, and transaction security verification.

[0005] However, current technologies lack in-depth research on the hierarchical structure of quantum encrypted communication. Applications to vulnerable channels often remain at the level of conventional data transmission, lacking consideration for multi-channel separation and differentiated functional adaptation, leading to decreased system security. Furthermore, existing technologies lack further consideration for node types, resulting in most nodes in gas systems having similar functions and encryption procedures in quantum key transmission and application. This reduces the difficulty of attacks and poses a significant threat to gas system data security.

[0006] Based on this, this invention proposes a method and system for secure transmission of gas data based on quantum encrypted communication, used to construct a practical quantum encrypted communication device including a quantum key distribution (QKD) device and a quantum encryption terminal. Based on the key distribution mechanism of the quantum key distribution device, this invention establishes a hierarchical quantum channel model. Through secure interoperability between vulnerable quantum channels and strong encryption channels, it constructs a complete quantum encrypted communication system encompassing attack interference, quantum encryption, and communication negotiation information, providing security monitoring, identity authentication, and transaction security functions for the quantum encrypted communication transmission of gas data. Furthermore, this invention uses clustering configuration of key distribution to monitor the operating status of the quantum encrypted communication system in real time through a hierarchical classification approach, including key indicators such as bit error rate and device status. It achieves hierarchical management of quantum keys for different gas system devices, providing stronger system data security and device management efficiency compared to existing technologies.

Based on a specific clustering algorithm, the node's home device and region are used as the algorithm's input parameters. The pre-configured node home information is clustered, and a unified cluster identifier ID is configured for transmission nodes belonging to the same cluster, thus setting them as a single cluster.

[0014] Preferably, the use of the first fragile quantum channel as an interference channel, the second fragile quantum channel as a key transmission channel, and the third fragile quantum channel as a quantum-based communication channel specifically refers to: The first vulnerable quantum channel serves as an interference channel to attract attacks, enabling attackers to bypass or reduce their attacks on the second vulnerable quantum channel by attacking the first vulnerable quantum channel.

These terms are only used to distinguish the keywords from each other. For example, without departing from the scope of the embodiments of the present invention, a first vulnerable quantum channel, a first quantum encryption algorithm, etc., may also be referred to as a second vulnerable quantum channel, a second quantum encryption algorithm, etc., and a second vulnerable quantum channel, a second quantum encryption algorithm, etc., may also be referred to as a first vulnerable quantum channel, a first quantum encryption algorithm.

[0026] Depending on the context, the word "if" as used here can be interpreted as "when," "when," "in response to determination," or "in response to detection." Similarly, depending on the context, the phrase "if determination" or "if detection (of the stated condition or event)" can be interpreted as "when determination," "in response to determination," "when detection (of the stated condition or event)," or "in response to detection (of the stated condition or event)."

[0027] As per the instruction manual Figure 1 The diagram shown is a basic example of a gas data security transmission system based on quantum encrypted communication according to the present invention. As a preferred embodiment that can be superimposed, each node or module can preferably interconnect with other nodes or modules for data and command transmission. Of course, as another preferred embodiment that can be superimposed, some nodes may not have interconnection with some other nodes, or may be allowed to disable or enable interconnection with other nodes.

[0028] The gas data secure transmission method and system based on quantum encrypted communication claimed in this invention includes a quantum key distribution (QKD) device and a quantum encryption terminal, characterized in that the system further includes at least: The gas-fired quantum key distribution module establishes a fragile hierarchical quantum channel model based on a quantum key distribution (QKD) device, which includes three fragile quantum channels and one strong encrypted quantum channel. The data encryption transmission module, based on the fragile hierarchical quantum channel model and node information, gas data and system command information, performs hierarchical quantum encryption transmission based on differentiated quantum keys; The system management platform receives information transmitted from the fragile hierarchical quantum channel model and performs detection and quantum bit error rate calculation. The security monitoring module, based on security monitoring requirements, determines the negotiated communication quantum base, receives key distribution model cluster information transmitted through a strongly encrypted quantum channel, and compares whether the quantum key corresponding to the cluster is consistent with the second quantum key. The identity authentication module is used to verify the legitimate identities of the quantum encryption terminals at both the sending and receiving ends; The transaction security module encrypts contract information and logistics information at the receiving end quantum encryption terminal based on the second quantum key, and compares the result of whether the quantum key corresponding to the cluster is consistent with the second quantum key. If the result is consistent, the receiving end quantum encryption terminal performs parsing of contract information and logistics information based on the second quantum key.

[0029] To further differentiate itself from existing technologies, as a preferred embodiment that can be superimposed, the identity authentication module verifies the identity IDs of the sending and receiving quantum encryption terminals based on a specific identity authentication digest algorithm. It then combines this with a pre-set list of permitted identity IDs to determine whether the ID is a permitted identity ID. If so, the identity is confirmed to be legitimate.

When the quantum key corresponding to the cluster of the relevant node matches the second quantum key received in this transmission, it confirms that the key has not been interfered with or tampered with. Contract information parsing and logistics information parsing are then performed, and based on the node information within the contract information and logistics information data structures, it is confirmed that both the contract information and logistics information point to the same node.

[0031] As per the instruction manual Figure 2The diagram shown is a basic example of a fragile hierarchical quantum channel model in a gas data secure transmission system based on quantum encrypted communication, as illustrated in this invention.

Node information, gas data, system command information, and the second quantum key, encrypted with the first quantum encryption algorithm and the second quantum key, are sent to the second vulnerable quantum channel. Base negotiation communication information is encrypted with the second quantum encryption algorithm and the second quantum key and then sent to the quantum base communication channel.

[0033] As another preferred embodiment that can be superimposed, the system management platform receives information transmitted by the fragile hierarchical quantum channel model and performs detection and quantum bit error rate calculation, including at least: The first vulnerable quantum channel transmits information and performs information silence, without performing detection or quantum error rate calculation, and is only used for pseudo-target attacks; it receives information transmitted through the second vulnerable quantum channel, performs detection and quantum error rate calculation, and after passing the quantum error rate detection, extracts the second quantum key and parses node information, gas data and system instruction information; The security monitoring module, based on security monitoring requirements, determines the negotiated communication quantum basis, receives key distribution model cluster information transmitted via a strongly encrypted quantum channel, and compares whether the quantum key corresponding to the cluster is consistent with the second quantum key, including at least: The system receives encrypted information from the quantum base communication channel, decrypts the base negotiation communication information based on the second quantum key from the system management platform, and determines the communication quantum base negotiated by the quantum encryption terminals of the sending and receiving ends based on the base negotiation communication information; it receives and parses the cluster information of the key distribution model transmitted through the strong encryption quantum channel, determines the cluster to which the node belongs based on the node information transmitted through the key transmission channel, and compares whether the quantum key corresponding to the cluster is consistent with the second quantum key. If they are consistent, the system passes the security monitoring.

[0034] As another preferred embodiment that can be superimposed, the gas quantum key distribution module further includes a gas data transmission model construction submodule, which constructs a gas data transmission model based on gas data transmission nodes and information paths. The gas data transmission model includes at least each device node of the gas transmission system, the gas transmission path, and the system information management path. The gas data transmission model construction submodule performs node clustering based on the pre-configured node affiliation information of the system, sets transmission nodes belonging to the same category as the same cluster and configures a unified cluster identifier ID. The cluster information of the key distribution model is maintained as a database table, recording the quantum key corresponding to each cluster.

[0035] As per the instruction manual Figure 3 The diagram shown is an example of node clustering in a gas data secure transmission system based on quantum encrypted communication, as illustrated in this invention.

[0036] As another preferred embodiment that can be overlaid, the gas data transmission model construction submodule performs node clustering based on the pre-configured node affiliation information of the system, setting transmission nodes belonging to the same category as the same cluster and configuring a unified cluster identifier ID, specifically: The node affiliation information includes at least the upstream device of each node device in the gas data transmission model, i.e., the device to which it belongs; and the region to which the node belongs. Based on a specific clustering algorithm, the node's home device and region are used as the algorithm's input parameters. The pre-configured node home information is clustered, and a unified cluster identifier ID is configured for transmission nodes belonging to the same cluster, thus setting them as a single cluster.

[0037] As another preferred embodiment that can be superimposed, the use of a first fragile quantum channel as an interference channel, a second fragile quantum channel as a key transmission channel, and a third fragile quantum channel as a quantum-based communication channel specifically refers to: The first vulnerable quantum channel serves as an interference channel to attract attacks, enabling attackers to bypass or reduce their attacks on the second vulnerable quantum channel by attacking the first vulnerable quantum channel.
