Referring to FIG. 1, the blockchain-based distributed quantum network system 10 for an IoT network includes a terminal layer 11 in which at least one client terminal 111 is provided, and at least one device existing at a preset distance interval. It consists of an edge layer 13 provided with a plurality of edge servers 131 that communicate with the client terminal 111, and a cloud layer 15 provided with a quantum server 155 that communicates with a plurality of edge servers 131. do.

At least one client terminal 111, the edge server 131, and the quantum server 155 can communicate over a network. A network refers to a connection structure that allows information to be exchanged between nodes such as terminals and servers. These networks include the Internet, Wireless LAN (Wireless Local Area Network), WAN (Wide Area Network), and PAN. (Personal Area Network), 3G, 5G, LTE (Long Term Evolution), WiFi (Wireless Fidelity), WiMAX (World Interoperability for Microwave Access), WiGig (Wireless gigabit), etc., but are not limited to these.

Meanwhile, at least one client terminal 111 may be equipped with a wireless communication device that guarantees portability and mobility, an Unmanned Aerial Vehicle (UAV), a closed-circuit television (CCTV) of a smart factory, etc., and such wireless communication device PCS (Personal Communication System), GSM (Global System for Mobile communications), PDC (Personal Digital Celluar), PHS (Personal Handyphone System), PDA (Personal Digital Assistant), IMT (International Mobile Telecommunication)-2000, CDMA (Code Division) Multiple Access)-2000, W-CDMA (W-Code Division Multiple Access), Wibro (Wireless Broadband Internet) terminal, smartphone, smartpad, tablet PC, VR (Virtual Reality) device, HMD ( It may include, but is not limited to, all types of handheld wireless communication devices such as Head Mounted Display, etc., and may be used depending on the field to which the blockchain-based distributed quantum network system for IoT networks (10) is applied. It can be equipped with other wireless communication devices or devices capable of communication such as UAV and CCTV.

In this regard, the blockchain-based distributed quantum network system 10 for an IoT network can configure at least one client terminal 111 existing at a preset distance interval into one cluster.

In addition, the blockchain-based distributed quantum network system 10 for IoT networks exists in a cluster and is connected to a base station, that is, a base station, to any one client terminal 111 that has been previously authenticated as a trustworthy client terminal 111. By assigning roles, different client terminals 111 existing in the cluster can be managed.

In addition, the blockchain-based distributed quantum network system 10 for IoT networks combines and inputs the client terminals 111 assigned to the base station in each cluster into the blockchain provided in the edge server 131 to connect each client. Authentication of the terminal 111 may be performed or communication with the client terminal 111 may be performed.

At least one client terminal 111 collects data and generates a data processing request message including the data.

Here, the data collected by at least one client terminal 111 is information or records collected by each client terminal 111 according to the user's command, and this information or records are IoT raw data, which is very sensitive and personalized. This is data that necessarily requires higher security measures to generate information.

Accordingly, at least one client terminal 111 may generate a data processing request message including its terminal information and collected data, and transmit the generated data processing request message to the edge server 131.

Referring to FIG. 2, when a client terminal 111 present in a cluster managed by the edge server 131 transmits a data processing request message, the edge server 131 sends a data processing request message to the client terminal 111 that generated the data processing request message. The client terminal 111 is verified by inputting the terminal information and data processing request message into a previously prepared blockchain.

More specifically, the edge server 131 can confirm whether the client terminal 111 is a safe and verified terminal by transmitting terminal information to the verification authority node present in the blockchain 1311. Here, the confirmation authority node refers to a client terminal 111 assigned the role of a base station for managing the different client terminals 111 described above. Hereinafter, it will be described as a confirmation authority node.

The edge server 131 can check whether the client terminal 111 that transmitted the data processing request message is a client terminal 111 previously connected to the blockchain 1311 through the blockchain-based Practical Byzantine Fault Tolerance algorithm.

Subsequently, when any one client terminal 111 present in the cluster generates and delivers a data processing request message, the edge server 131 sends the terminal of the client terminal 111 to the confirmation authority node that verifies the client terminal 111. A confirmation request containing information may be forwarded.

At this time, the confirmation authority node verifies the client terminal 111 through the client ID stored in the terminal information of the client terminal 111, and if the client ID is the same as the client terminal 111 that generated the data processing request message, confirmation An authentication message for the request may be delivered to the edge server 131.

Accordingly, the edge server 131 verifies the identity of the client ID included in the terminal information with the client terminal 111 that generated and delivered the data processing request message through an authentication message transmitted from the confirmation authority node, and when confirmation is completed, , by further assigning the root role to the verification authority node that delivered the authentication message, message broadcasting can be performed up to a preset round.

Here, the confirmation authority node delivers the message to all client terminals 111 connected to the confirmation authority node up to a preset round, and among all client terminals 111, the client terminal 111 that generated the data processing request message responds to the message. Result messages can be transmitted up to a preset round.

Through this, when the confirmation authority node reaches a preset round, it is transformed into a commit state and can display the result generated through message broadcast as the number of messages delivered to all client terminals 111.

In addition, the confirmation authority node counts the number of result messages transmitted up to the 2f+1 round by the client terminal 111 that generated the data processing request message, and the result generated by broadcasting the number of messages and the commit status as a result of counting The number of messages can be transmitted to the edge server 131.

Through this, the edge server 131 compares the number of result messages delivered by the verification authority node and the number of messages generated by broadcasting the commit status of the storage of the verification authority node to the client terminal 111 that delivered the data processing request message. ) can be verified whether it is a client terminal 111 that exists in a pre-established blockchain. At this time, if the number of different messages is not the same through comparison, the edge server 131 may omit the data processing request message delivered by the client terminal 111.

As a result, the blockchain-based quantum network system 10 for IoT networks is secure and can provide the protection desired by users using the client terminal 111 by setting only authenticated client terminals 111 as part of the system, Only honest, verified users can use the system, enhancing security within the IoT network.

Meanwhile, referring to FIGS. 3 and 4, when the edge server 131 completes verification of the client terminal 111 that delivered the data processing request message, it inputs the data processing request message into the pre-prepared virtual quantum machine 133 to It can be converted to qubits.

Here, a qubit is the basic unit for calculation by a quantum computer, and is a bit that has the states of 0 and 1 simultaneously, and the virtual quantum machine 133 is located between the existing client terminal 111 and the quantum server 155 in the cloud layer 15. QMT (Quantum Machine Terminal) is used as a medium between

This QMT is equipped with an encoding gate and a compiler, reducing the need for a quantum computer in a cloud environment or smart city environment, and performing quantum-based encryption to strengthen communication security between the client terminal 111 and the quantum server 155. .

More specifically, the QMT provided in the edge server 131 can convert a data processing request message generated as a classic bit into a qubit using an encoding gate.

Additionally, QMT can encode the data processing request message converted to qubits using an encoding gate. At this time, the QMT is a plurality of gates 135 that communicate with the quantum server 155, and can transmit qubits by distributing Rx, Ry, and Rz Quantum Logical Gates in advance. here

[Equation 1]

[Equation 2]

[Equation 3]

In addition, the edge server 131 uses Rx, Ry, and Rz as gates 135 for transmitting data to the quantum server 155, and may further include a CNOT gate to transmit data.

Through this, the edge server 131 converts the data processing request message prepared as a classic bit into a plurality of qubits using QMT, and converts the converted qubits into one of the plurality of gates 135 provided as Rx, Ry, and Rz. It can be encoded in the gate 135 and transmitted to the quantum server 155.

Meanwhile, the edge server 131 may further provide QSDC (Quantum Secure Direct Communication) to improve the calculation perspective and error accuracy that occurs in the process of transmitting qubits to the quantum server 155.

If an emergency situation occurs in the process of delivering a qubit to the quantum server 155, the edge server 131 can deliver a secure message using QSDC without generating a separate shared secret key.

Additionally, the edge server 131 may further use QSDC to use QMT as a device for communicating with at least one client terminal 111 for which verification has been completed.

At this time, when verification is completed through the blockchain 1311 at the edge server 131, at least one client terminal 111 may perform separate encryption on the data processing request message and transmit it to the QMT through photons.

Here, photons can be polarized based on one of four main states: |H>,|V>, |u>, and |d>.

Additionally, the edge server 131 receives an encrypted data processing request message through QMT, randomly selects a set of photons to be measured, and can check whether an eavesdropper exists based on the concept of error rate.

Accordingly, if the error rate is low, the edge server 131 may determine that the communication channel is safe and maintain communication, and if the error rate is high, it may determine that an eavesdropper exists in the communication channel and stop communication.

Meanwhile, before delivering the data processing request message converted to qubits to the quantum server 155, the edge server 131 further performs quantum-based encryption by applying Q-OTP to the data processing request message converted to qubits. It can be done.

More specifically, the edge server 131 can apply the Q-OTP (Quantum One-Time Pad) shown in FIG. 12 to the data processing request message converted to qubits, where Q-OTP is a standard-based operation. It is an encryption technique that performs encryption by simultaneously using the

At this time, in order to apply Q-OTP using the can be further distributed.

Here, [Equation 4] is an equation representing encryption performed by applying Q-OTP to a data processing request message converted to qubits, and [Equation 5] is a data processing request encrypted through [Equation 4]. This is a mathematical expression that represents the decryption of a message.

[Equation 4]

Here, e is an encryption function, At this time, both X and Z operations are operations used to encrypt random qubits.

[Equation 5]

As such, Q-OTP defined by [Equation 4] and [Equation 5] can perform encryption with the values shown in FIG. 12.

Through this, the edge server 131 encodes the qubits of the data processing request message encrypted through Q-OTP into the prepared gate 135 among the plurality of gates 135 provided as Rx, Ry, and Rz to perform quantum processing. It can be delivered to the server 155.

The edge server 131 verifies at least one client terminal 111 by performing the algorithm shown in FIGS. 13 to 15, converts the data processing request message of the verified client terminal 111 into qubits, and , Encryption is performed by applying Q-OTP to the converted qubit, and the qubit of the encrypted data processing request message is encoded in the prepared gate 135 among the plurality of gates 135 provided as Rx, Ry, and Rz. You can.

Meanwhile, when the edge server 131 completes verification of the client terminal 111, the quantum server 155 analyzes the data processing request message and performs a data processing request.

More specifically, the quantum server 155 transmits the qubit of the encrypted data processing request message through the prepared gate 135 of the plurality of gates 135 provided by the edge server 131 as Rx, Ry, and Rz. , the data processing request message can be accessed through delegated quantum computing, and the data processing request of the client terminal calculated through access can be performed and stored. Here, delegated quantum computing can be prepared to maximize the use of quantum computing performance while protecting the user's data and computing security.

Accordingly, the quantum server 155 uses the gate protocol sequence shown in FIGS. 5 to 11 to perform data processing according to the data processing request message and calculation tasks for storing the message using delegated quantum computing. A quantum circuit consisting of a set of measured angles can be constructed. Here, the { You can.

Through this, the quantum server 155 accesses only the prepared gate 135 among the plurality of gates 135 provided by Rx, Ry, and Rz in which the edge server 131 encodes the qubits of the encrypted data processing request message. The data can be processed by analyzing the data processing request message, and the qubits of the encrypted data processing request message can be stored in the internal storage space.

As a result, the blockchain-based distributed quantum network system 10 for IoT networks improves computing power and security in the IoT environment and reduces the need to have a quantum machine on the client terminal 111 side. It can provide safe access between the quantum server 155 and the quantum server 155, and can provide the effect of performing complex calculations requested by the client terminal 111 while maintaining security for data stored in the quantum server 155.
