Background Technology

[0003] In general, water leakage in water supply and sewage networks leads not only to the loss of water resources but also to the need for additional pressurization equipment due to pressure loss and the weakening of soil around the leaking pipes, making network maintenance difficult and causing serious economic losses.

[0004] Accordingly, a monitoring system for efficient maintenance of water supply and sewage networks has been adopted and is in operation. In other words, it is a maintenance method that involves installing various instruments at the sites where water supply and sewage pipes are buried to allow the management bureau to constantly monitor flow rate, pressure, temperature, humidity, noise, etc., thereby enabling active response to leakage accidents and preventing leakage in advance to improve the water efficiency.

[0005] Typically, a leak monitoring system detects impacts and leaks in buried water and sewage pipes by processing and analyzing external data, such as flow rate, pressure, temperature, humidity, and noise, detected by various instruments capable of detecting such impacts and leaks using a central processing unit and internal / external programs, and operates and manages the entire system through a central system.

[0006] This leak monitoring system monitors leakage situations by supporting the transmission of leak monitoring data based on communication. Regarding the communication system for the leak monitoring system, a security system applicable between components was required to enable the reliable transmission of leak monitoring data through secure bidirectional communication between field instruments, the upper-level system, and the central system.

[0039] FIG. 1 is a drawing showing a leak monitoring system for a water supply / sewer network integrated with a quantum security communication device according to one embodiment of the present invention.

[0040] Referring to FIG. 1, a leak monitoring system (10) for a water / sewer network integrated with a quantum security communication device may include a leak monitoring unit (100) for a water / sewer network and a central leak monitoring processing unit (200). Here, the leak monitoring unit (100) for a water / sewer network and the central leak monitoring processing unit (200) may be connected via wireless communication such as satellite communication, 4G, 5G, 6G, WiFi, TVWS, or wired communication such as Ethernet or serial communication.

[0041] A water / sewer network leak monitoring unit (100) may correspond to a field monitoring unit capable of detecting data for leak monitoring of a buried network and transmitting the detected leak monitoring data after quantum encryption, and may include a leak monitoring module (110), a DIM (Device Identity Module) (130), a security module (150), and a communication interface unit (170).

[0042] The leak monitoring module (110) can generate leak monitoring data. Here, the leak monitoring data may include data representing various physical quantities such as flow rate, pressure, temperature, humidity, and noise of the pipes of the water supply / sewer network detected through various instruments.

[0043] The DIM (Device Identity Module) (130) is implemented as a separate, independent chipset and can perform the injection of a quantum security key according to the administrator's settings and can include a quantum security device identification key. The DIM (130) can receive a quantum security key from the central leak monitoring processing unit (200) and can generate a quantum security device identification key by performing quantum security on the device unique number using the quantum security key.

[0044] Quantum-Safe Security refers to security technology that cannot be breached even by the computational power of quantum computers utilizing the principles of quantum mechanics. Currently, quantum security is divided into hardware-based Quantum Key Distribution (QKD) and software-based Post-Quantum Cryptography (PQC). QKD refers to a technology that enables two users to secretly share a key (a type of random password) necessary for encrypted communication by utilizing the no-cloning theorem and the collapse of the wave function phenomena in quantum mechanics. PQC can provide not only key distribution but also all the functions necessary for secure encrypted communication. In other words, it can provide encrypted communication involving the steps of generating a password key randomly through a Pseudo Random Number Generator (PRNG) or a Quantum Random Number Generator (QRNG), user authentication, key distribution (or sharing), and encryption using the shared key through a secret key (symmetric key) encryption algorithm such as AES or SEED; in the case of public key cryptography (PQC), encrypted communication is possible without using a secret key (symmetric key) encryption algorithm.

[0045] Here, DIM (130) performs quantum security by generating random numbers through quantum random numbers.

[0046] The security module (150) can generate quantum security leak monitoring data by performing quantum security operations on the leak monitoring data using a quantum security device identification key and a quantum security key through the DIM (130). If the DIM (130) does not operate normally, the security module (150) can receive a public key from the central leak monitoring processing unit (200) and perform security operations on the leak monitoring data using the public key to replace the quantum security leak monitoring data with public key security leak monitoring data. The security module (150) can perform encryption and decryption of the leak monitoring data, and a key such as a quantum security key or a public key may be used in this process.

[0047] Public-key cryptography is an asymmetric key method in which different keys are used for encryption and decryption. It involves generating a key pair consisting of a public key and a private key using a specific algorithm, then encrypting with the public key and decrypting with the private key.

[0048] The communication interface unit (170) can transmit quantum security leakage monitoring data for a given communication environment. Here, the communication environment refers to a communication method that can be integrated and interconnected with all of the following: satellite communication, wireless communication such as 4G, 5G, 6G, WiFi, TVWS, LoRa, and wired communication methods such as Ethernet, Serial 232, 485, so there is no need to rely on the security of individual communications.

[0049] The central leak monitoring processing unit (200) receives quantum security leak monitoring data, extracts a device identification key, determines a quantum security key based on the device identification key to detect leak monitoring data, and can process quantum security key injection by performing quantum key distribution to the DIM (130) in advance. In one embodiment, the central leak monitoring processing unit (200) is a higher-level system of the leak monitoring unit (100) for water supply / sewer network, and may correspond to a management server that monitors impact and leaks in the pipes of the water supply / sewer network from a remote location. At this time, the central leak monitoring processing unit (200) may correspond to a higher-level system that applies a virtualized cloud environment rather than just a fixed server.

[0050] The central leak monitoring processing unit (200) detects whether the DIM (130) is operating normally and, if the DIM (130) is operating normally, can perform quantum security key injection, and if the DIM (130) is not operating normally, can provide an RSA or ECC-based public key to the security module (150).

[0051] RSA (Rivest, Shamir, Adleman) is a public-key cryptographic algorithm consisting of a public key and a private key; the public key is used to encrypt a message, and the private key is used to decrypt the encrypted message. ECC (Elliptic Curve Cryptosystem) is a public-key cryptographic algorithm that utilizes the mathematical properties of elliptic curves and provides stronger security compared to RSA for the same key length.

[0053] Figure 2 is a block diagram showing the Device Identity Module (DIM) of the water / sewer network leak monitoring unit in Figure 1.

[0054] Referring to FIG. 2, the DIM (130) of the water / sewer network leak monitoring unit (100) is implemented as a single chipset including a power interface (210), a reset interface (220), an SWD interface (230), a UART interface (240), quantum security firmware (250), and a quantum entropy chip (QEC) (260), and can perform the injection of a quantum security key according to the administrator's settings and can include a quantum security device identification key.

[0056] The reset interface (220) can receive a reset signal to reset the quantum security firmware (250). Here, the reset signal may be provided to the reset interface (220) according to the administrator's settings. In one embodiment, the reset signal may be configured to be provided to the reset interface (220) whenever leak monitoring data is generated in the leak monitoring module (110) and provided to the DIM (130).

[0057] The SWD (Serial Wire Debug) interface (230) can provide programming and debugging to the MCU to which the quantum security firmware (250) is downloaded.

[0058] The UART interface (240) is connected to the leak monitoring module (110) and provides leak monitoring data to the quantum security firmware (250), and can provide the quantum security leak monitoring data generated from the quantum security firmware (250) to the communication interface unit (170).

[0059] Quantum security firmware (250) can receive a quantum security key from the central leak monitoring processing unit (200) based on a reset signal and generate a quantum security device identification key by performing quantum security on the device unique number using the quantum security key. Quantum security firmware (250) can receive leak monitoring data and generate intermediate quantum security leak monitoring data based on the quantum security key. Quantum security firmware (250) can receive leak monitoring data in a UART (Universal Asynchronous Receiver / Transmitter) communication environment. Quantum security firmware (250) can generate quantum security leak monitoring data by merging the quantum security device identification key with the intermediate quantum security leak monitoring data. Quantum security firmware (250) can provide quantum security leak monitoring data to the communication interface unit (170) through the DUSS (Different Unit Same Security) protocol, which is independent of the given communication environment.

[0060] A quantum entropy chip (hereinafter referred to as QEC) (260) can generate a quantum random number entropy source (noise source) to provide analog noise to the quantum security firmware (250). At this time, the analog noise can be generated to have sufficient entropy to generate an unpredictable encryption seed. In one embodiment, the QEC (260) may correspond to a noise source operating system implemented in software such as Android, Linux, or Windows. In one embodiment, the QEC (260) may be implemented in hardware by utilizing non-deterministic phenomena in electronic circuits, such as shot noise of a Zener diode or inherent thermal noise of a semiconductor circuit, or by utilizing physical phenomena such as radiation decay. In one embodiment, the QEC (260) may be implemented by combining software and hardware.

[0062] Figure 3 is a block diagram showing the functional configuration of quantum security firmware in the Device Identity Module (DIM) in Figure 2.

[0063] Referring to FIG. 3, the quantum security firmware (250) of the DIM (130) includes a security function processing unit (310), a cryptographic algorithm processing unit (320), an important security parameter processing unit (330), a finite state processing unit (340), an instruction set-based security agent protocol processing unit (350), and an input / output data processing unit (360) to perform quantum security and generate a quantum security device identification key and quantum security leak data.

[0064] The security function processing unit (310) is divided into an important security parameter management function, a cryptographic algorithm setting function, and a cryptographic algorithm execution (data input) function to provide cryptographic algorithm services to the administrator. The list of security parameters and supported cryptographic algorithms can be exemplified as shown in Tables 1 and 2 below.

The cryptographic algorithm processing unit (320) supports the ECDSA algorithm for digital signatures and the ECDH algorithm for key setting, so that it can be applied to wireless communication such as 4G LTE, 5G, 6G, satellite, and TVWS, and IoST environments such as WiFi, LTE Cat.m1, NB-IoT, and LoRa for IoT security of water supply / sewer networks.

[0070] The important security parameter processing unit (330) is a layer that processes core security parameters and public security parameters, and is responsible for the creation, setting, injection, output, storage, and zeroing of security parameters.
