Description

Technical Field

[0001] The present invention mainly belongs to the field of blockchain technology, and specifically relates to a spectrum auction transaction method and device based on blockchain and quantum encryption. Background Art

[0002] In recent years, scarce spectrum resources have become increasingly sought-after due to their enormous potential economic value. However, most spectrum resources are held by only a few institutions and companies and are considered private, not shared with other demand parties. This has led to a significant increase in demand for spectrum auctions. Typically, a typical spectrum transaction involves two parties: the relevant government departments that hold national spectrum resources and large, state-owned enterprise buyers. Buyers submit their requirements to the relevant government departments, which then organize centralized bidding auctions for their spectrum. The auctioned spectrum is then packaged and leased to the winning large enterprises for a long period of time. While some work has been done to design spectrum trading systems, most rely on a trusted third party—a centralized auction organization trusted by the National Spectrum Resources Administration. These systems cannot auction spectrum resources in real time, and users may doubt the reliability of transactions. Furthermore, transaction performance issues can reduce user participation and resource utilization efficiency.

[0003] Spectrum trading between virtual optical networks. According to Cisco, global IP traffic will reach 4.8 ZB per year by 2022, and peak-hour internet traffic will grow faster than average internet traffic. To address these challenges, virtual optical networks (VONs) partition the underlying optical network (e.g., elastic optical network, EON) into multiple shared VONs. Most existing VON research assumes a fixed amount of bandwidth is allocated to each VON. However, VON traffic demand fluctuates moment-to-moment, and this variability can be captured by CR. To overcome these difficulties, several adaptive VON resource allocation methods have been proposed, such as incentive-driven VNF service chaining in inter-data center elastic optical networks (IDCNs): a hierarchical game theory mechanism and mixed-strategy game-based incentive-driven agent-based VNF service chaining provisioning in elastic optical data centers. These mechanisms require coordination with operators and allow them to allocate different amounts of bandwidth to different users under different scenarios. However, the drawbacks are that excess spectrum resources cannot be returned to operators, and transactions require operator monitoring, which increases operator pressure. Summary of the Invention

[0004] In response to the above-mentioned technical problems, the purpose of the present invention is to provide a spectrum auction transaction method based on blockchain and quantum encryption. The present invention independently designs a transaction confirmation algorithm based on blockchain and quantum encryption based on spectrum characteristics, aggregates the information of spectrum resource owners participating in the transaction and buyers competing for purchase, and realizes anonymous transactions through a self-designed anonymous module, thereby reducing transaction delays and energy loss. This method effectively meets the needs of buyers and sellers for leasing and trusted purchase of spectrum resources. In order to achieve the above-mentioned invention purpose, the present invention provides the following technical solutions: A spectrum auction transaction method based on blockchain and quantum encryption, comprising the following steps:

[0005] S01. Based on the seller's pre-sale information and the buyer's purchase demand information, the seller sells its spectrum resources and sets the start clock T1. The seller collects bids and selects buyers. Quantum cryptography technology is also introduced, using quantum keys and authentication methods during the transmission and confirmation of transaction information to ensure confidentiality and immutability of transaction information.

[0006] S03. When the seller and buyer reach an agreement, the seller's node confirms the transaction information and satisfies The seller then broadcasts that the transaction is legal. The seller declares the transaction a failure;

[0007] S05. Other nodes receive the pre-sale message, and the T2 clock starts counting. If the node is a buyer, it encrypts and sends its bid using quantum cryptography. When the seller accepts the bid, the buyer and seller reach an agreement and confirm the transaction is legitimate.

[0008] S07. When the node receives the transaction information, the T2 clock stops. When the node waits for a period not exceeding The time to decide whether the transaction is confirmed, It is determined by the quantum cryptography parameters. If confirmed, the transaction information is confirmed to be legal. Otherwise, the node will immediately confirm that the transaction has failed. When the node receives a transaction failure from the seller, the transaction will also fail. The transaction confirmation delay TD is mainly related to the propagation delay (tt) and the consensus protocol delay (ta). TD = tt*r+ta, where r is the number of rounds of message propagation.

[0009] After step S07, a determination system is also included to resist mainstream attacks, and the determination system specifically includes: double-spending attacks, distributed denial of service attacks, and private mining attacks.

[0010] Before step S01, the following steps are also included:

[0011] The operator initializes spectrum resource allocation, forms a one-to-one mapping of spectrum resources at the virtual optical network layer, monitors spectrum occupancy through cognitive radio technology, and provides resource status support for the blockchain auction platform; the seller node will query its current spectrum status through the cognitive wireless network.

[0012] The spectrum status specifically includes: which frequency slots are in use, the usage period of the frequency slots, and which frequency slots are idle.

[0013] The method also includes a contribution value module, which specifically includes the following steps:

[0014] a. All nodes will receive corresponding contribution value in the initial stage;

[0015] b. Once the spectrum transaction is confirmed, the contribution value will be transferred according to the transaction;

[0016] c. Mining penalty blocks, the system will reward them for their contribution value;

[0017] d. A node can maintain a contribution value table of the associated frequency slot committee. The contribution value table represents the current contribution value of the associated node. When the node updates its granularity chain and answer chain, it can synchronously update the contribution value table.

[0018] The method also includes a blockchain transaction confirmation system, which includes: a physical link layer at the bottom layer, a virtual optical network layer above it, a cognitive wireless circuit layer, and a blockchain spectrum transaction layer;

[0019] The physical link layer module is mainly implemented by elastic optical network, an application of wavelength division multiplexing, which can operate on very closely spaced frequencies and the spectrum resource allocation is initialized by the operator;

[0020] The virtual optical network layer module, the elastic optical network, and the virtual optical network correspond one-to-one, and together with radio cognitive technology, implement spectrum auction transactions. The life cycle of the virtual optical network is divided into multiple time intervals, and in each time interval, the virtual optical network will obtain a certain frequency slot required for spectrum resources.

[0021] Valid spectrum transactions are confirmed through a distributed consensus algorithm, primarily based on the confirmation of different nodes. Blockchain spectrum leverages a distributed consensus algorithm, aggregating information from participating spectrum resource owners and competing buyers to confirm transactions. Anonymous transactions are achieved through an anonymity module, while computational energy consumption is reduced through an optimization module. Buyers and sellers leverage this distributed consensus algorithm to achieve spectrum leasing and trusted purchases.

[0022] The frequency slots are independent of each other and not highly continuous, and consistency is ensured on the granularity chain for a specific frequency slot.

[0023] When a node broadcasts the puzzle answer chain, it also broadcasts a legal transaction at the same time. It will also follow the principle of majority rule in penalty blocks and transaction blocks, and select the longest chain principle to confirm the legal answer chain.

[0024] A device for spectrum auction transaction method based on blockchain and quantum encryption includes three main components: a blockchain transaction confirmation system, a set of seller nodes registered on the network, and a set of buyer nodes registered on the network;

[0025] The blockchain transaction confirmation system is divided into four layers: the physical link layer at the bottom, the virtual optical network layer, the cognitive wireless circuit layer, and the blockchain spectrum transaction layer above it;

[0026] The seller node prepares a pre-sale message based on the frequency bands owned by the seller and the corresponding leasing schedule returned by the cognitive neural network;

[0027] The buyer node is a registered buyer who has passed the authentication. The buyer will conduct competitive bidding for his own information and the target frequency band, including the frequency band, price, lease time, lease party information, etc. The buyer must also participate in the verification of the information.

[0028] A device for a spectrum auction trading method based on blockchain and quantum encryption, comprising a memory, a processor, and a computer program stored in the device and executable on the processor. When the processor executes the program, the spectrum auction trading method based on blockchain and quantum encryption as claimed in the claims is implemented.

[0029] Compared with the prior art, the advantages of the present invention are:

[0030] (1) Different from the direct centralized long-term authorization in the traditional spectrum auction trading system, the present invention provides a spectrum auction trading method based on blockchain and quantum encryption. The present invention independently designs a transaction confirmation algorithm based on blockchain and quantum encryption based on spectrum characteristics, aggregates the information of spectrum resource owners participating in the transaction and buyers competing for purchase, realizes anonymous transactions through the anonymous technology designed by itself, and reduces transaction delays and energy loss.

[0031] (2) Quantum cryptography is used in some steps, making trust management more reliable. This also makes the encryption process more scalable. In scenarios where quantum devices are unavailable, classical cryptography can be used instead. This effectively combines quantum cryptography with blockchain.

[0032] (3) The present invention provides a spectrum auction transaction method based on blockchain and quantum encryption, which effectively achieves high utilization of scarce spectrum resources and solves the unavailable needs of small and medium-sized enterprises, and ensures the trusted management of spectrum resources and good scalability of the system. Therefore, the present invention has strong practical value and has broad market prospects for the popularization of spectrum auction transaction methods based on blockchain and quantum encryption.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The above scheme is further described below in conjunction with specific examples. These examples are used to illustrate the present invention and are not intended to limit the scope of the present invention. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer. The implementation conditions not specified are generally those used in routine experiments.

[0042] Example 1

[0043] This embodiment provides a spectrum resource auction transaction method based on blockchain and quantum encryption, such as Figure 1 As shown, the following steps are included:

[0044] (1) The operator initializes spectrum resource allocation, forms a one-to-one mapping of spectrum resources at the virtual optical network layer, and monitors spectrum occupancy through cognitive radio technology. This provides resource status support for the blockchain auction platform.

[0045] (2) Use a distributed consensus algorithm to confirm valid spectrum transactions. Confirming a transaction is mainly based on different nodes. If it is a seller node, the seller node will broadcast the pre-sale message. Figure 4 The display shows that the honest node virtual optical network b (VONb) broadcasts the pre-sale message, and other nodes verify whether b is the real holder; at this time, the clock T1 starts, and the seller will collect bids and select the best seller. According to the previous explanation, When the buyer and seller reach an agreement and confirm the transaction information, the seller broadcasts the transaction as legal and writes it into the distributed consistent ledger. Otherwise, the seller's broadcast transaction fails, and the node re-collects information and starts the transaction. It can ensure the strong sequence of local and global chains, such as Figure 2 In this embodiment, blockchain spectrum mainly uses the blockchain distributed consensus algorithm to aggregate the information of spectrum resource owners participating in the transaction and buyers competing for purchase, realize transaction confirmation, realize anonymous transactions through the anonymity module, and reduce computing energy loss through the optimization module. Buyers and sellers use this distributed consensus algorithm to achieve spectrum leasing and trusted purchase.

[0046] (3) When the transaction starts, if it is another node, the node receives the pre-sale message, and the clock T2 starts to count. Is the node a buyer? If yes, the buyer sends its bidding information. If no, it returns to the node to collect the pre-sale message. At this time, it will confirm that the node is a buyer and the seller accepts the bidding information. If yes, the node is asked to check whether the transaction information received by the node is legal. If yes, the clock T2 stops and the judgment is made. When the node waits for a sufficiently long time (no less than is the quantum encryption parameter) to decide whether the transaction should be confirmed. If so, the transaction is confirmed to be legal and then written into the distributed consistent ledger. Figure 3 The explanation is that the verification field is added to the transaction block; if not, the transaction received by the node from the seller fails, the transaction fails, and the transaction is restarted. If the node receives legal information, if not, it is also announced that the transaction received by the node from the seller fails and returns to restart the transaction.

[0047] (4) A spectrum distributed consistent ledger is formed for node query, which requires quantum encryption.

[0048] This example uses omnetpp to simulate a network, with messages between nodes transmitted via a gossip protocol. To simulate a real-world deployment, the latency on each communication link is increased to 300-800 milliseconds. To meet the requirements of high-frequency trading, each frequency slot (FS) is set to no more than 10-1000 milliseconds, and honest nodes immediately announce pre-sale information after using a frequency slot. Multiple tests have demonstrated excellent experimental results and strong practical significance. Figure 5 The figure shows a comparison between the energy loss of the present invention and the traditional Bitcoin model. In the figure, the energy loss is A>B>C>D. The energy loss of traditional Bitcoin is A, and the energy loss of the present invention is D, which shows that the present invention has the effect of green energy saving.

[0049] This case experiment is conducted on a network of 10-30 nodes. Figure 6 and Figure 7 This spectrum auction transaction method based on blockchain and quantum encryption effectively achieves high utilization of scarce spectrum resources and addresses the unavailable needs of small and medium-sized enterprises. It also ensures trusted management of spectrum resources and low latency in transactions. Therefore, the present invention has strong practical value and broad market prospects.

[0050] 1) Double-spending attacks: In a system using quantum cryptography, it's impossible for a malicious node to sell the same spectrum resources to different buyer nodes and have them confirmed. Quantum cryptography provides secure key distribution and authentication methods, ensuring the confidentiality and immutability of transaction information. Through quantum key distribution, transacting parties can establish a secure communication channel, preventing information theft or tampering. Therefore, using quantum cryptography in a system effectively eliminates the double-spending issue and returns ownership to the original owner.

[0051] 2) Targeting DDoS (Distributed Denial of Service) attacks: Due to the nature of hashing, buyers can publicly disclose their identities and provide detailed evidence to prove their identities. If a seller is malicious and a DDoS attack occurs, the buyer will immediately discover that the information was leaked from the seller. This information will also be exposed during penalty blocks, potentially triggering a DDoS attack. In this case, sellers are encouraged to sell all remaining spectrum resources, which will be returned to the operator when ownership is restored.

[0052] 3) Targeting unauthorized mining: This system targets penalty blocks, which contain necessary pre-sale information. Unauthorized mining cannot have the same pre-sale information. The introduction of quantum cryptography makes unauthorized mining even more difficult. The spectrum auction and trading system method based on blockchain and quantum cryptography should also include, before step S01, the formalization of specific spectrum resources to provide a foundation for subsequent blockchain transactions. Specifically, it includes:

[0053] 1) The operator first initializes spectrum resource allocation on the virtual network layer (VON) based on the initial physical connection network (EON). Then, the cognitive radio interacts with the surrounding environment to sense and utilize the available spectrum in the space, creating a spectrum usage record. The seller node queries its current spectrum usage through the cognitive radio network, specifically including which FSs are currently in use, their usage expiration dates, and which FSs are idle, to prepare a detailed record of the current spectrum resource status.

[0054] 2) Granular Chain: Spectrum resources are indivisible and independent, and spectrum also has a minimum indivisible granularity. This design calls this minimum indivisible granularity "Frequency Slot (FS)." This design uses GranularChain to record the transaction history of the corresponding FS owner.

[0055] 3) In this protocol, transaction broadcasting and submission are performed by the seller and buyer themselves. This significantly reduces transaction confirmation latency. Furthermore, global transactions can maintain strong consistency across granular chains.

[0056] 4) Based on the ownership transfer issue during spectrum auctions, a granular chain will be used to record spectrum owner information. The spectrum segment committee designed in this paper will record and broadcast granular chain information related to itself based on sharing, providing records and consensus support for normal and trusted spectrum transactions. The committee will prevent forks by collecting signatures.

[0057] 5) To maintain the operation of the system, a reasonable incentive mechanism will be designed. Similar to other designs, the token of this design is named contribution value (CV).

[0058] a. All nodes will get corresponding CV in the initial stage

[0059] b. After the spectrum transaction is confirmed, CV will be transferred according to the transaction

[0060] c. Mining penalty blocks, the system will give its CV reward.

[0061] d. A node can maintain a CV table of the associated FS committee. The CV table indicates the current CV of the associated node. When the node updates its granular chain (GranularChains) and answer chain, it can synchronize the updater CV table.

[0062] In the spectrum auction trading system method based on blockchain and quantum encryption, two time periods T1 and T2 are set for all orders to determine whether the transaction is legal and finally write it into the distributed ledger.

[0063] In the spectrum auction trading system method based on blockchain and quantum encryption, in step S01, the seller broadcasts a pre-sale message including a legal random number and announcing his identity. Other nodes verify whether he is the owner of the FS by verifying the random number and identity information.

[0064] A spectrum auction transaction method based on blockchain and quantum encryption also includes a blockchain transaction confirmation system, which includes: a physical link layer at the bottom layer, a virtual optical network layer above it, a cognitive wireless circuit layer, and a blockchain spectrum transaction layer;

[0065] The physical link layer module is mainly implemented by elastic optical network, an application of wavelength division multiplexing, which can operate on very closely spaced frequencies and the spectrum resource allocation is initialized by the operator;

[0066] The virtual optical network layer module, the elastic optical network, and the virtual optical network correspond one-to-one, and together with radio cognitive technology, implement spectrum auction transactions. The life cycle of the virtual optical network is divided into multiple time intervals, and in each time interval, the virtual optical network will obtain a certain frequency slot required for spectrum resources.

[0067] The blockchain spectrum trading layer module primarily utilizes a blockchain distributed consensus algorithm, aggregating information from participating spectrum resource owners and competing buyers to confirm transactions, prevent forks, and improve spectrum utilization. It also utilizes proprietary anonymity technology to enable anonymous transactions, reduce transaction latency, and optimize its design to reduce computing power consumption. Buyers and sellers utilize this distributed consensus algorithm to enable spectrum leasing and trusted purchases.

[0068] In the spectrum auction transaction method based on blockchain and quantum encryption, the transaction confirmation delay (TD) is mainly related to the propagation delay (tt) and the consensus protocol delay (ta). TD = tt*r+ta, where r is the number of rounds of message propagation. Since this design has a small number of rounds and a very low latency consensus algorithm, its transaction confirmation latency is also very low.

[0069] Even a chaotic global transaction order will not affect the validity of the protocol. This is because the FS corresponding to each transaction is independent of each other, and global transactions involving all FS do not need to be highly continuous. It is easy to ensure strong consistency for a specific FS on the GranularChain.

[0070] The chain of solutions to the difficulty value may cause forks. This design uses the longest chain solution chain as the legitimate chain to avoid forks in the FS GranularChain. Following the principle of majority rule, a legitimate block needs to collect signatures from more than half of the FS committee members. Collective signatures can be used to quickly collect signatures.

[0071] When a node broadcasts the answer to the puzzle, it also broadcasts a legal transaction at the same time. It will also follow the principle of majority rule in penalty blocks and transaction blocks, and select the longest chain principle to confirm the legal answer chain.

[0072] Example 2

[0073] This embodiment provides a device for a spectrum auction transaction method based on blockchain and quantum encryption, which includes three main components: a blockchain transaction confirmation system, a set of seller nodes registered on the network, and a set of buyer nodes registered on the network.

[0074] The seller node prepares a pre-sale message based on the FS bands it holds ownership of and the corresponding lease schedule, as returned by the cognitive neural network. This pre-sale message includes a proof-of-work puzzle. Before other nodes can solve the puzzle, the seller node must broadcast the legitimate information in the message. If other nodes fail to broadcast the solution, this means the seller node has not completed the broadcast within the time limit and will be penalized. This penalty immediately releases the seller node's FS ownership and returns it to the previous owner. The seller node also collects bids and selects the best buyer.

[0075] Buyer nodes are registered buyers who have passed verification. Buyers will submit their own information and competitive bidding for the target frequency band, including the frequency band, price, lease time, leaser information, etc. Buyers must also participate in the verification of information.

[0076] The blockchain transaction confirmation system consists of four layers: the physical link layer at the bottom, followed by the virtual optical network layer, the cognitive radio circuit layer, and the blockchain spectrum trading layer. The physical link layer will be initialized by the operator to allocate spectrum resources. The virtual optical network will map the hardware layer's spectrum resources one by one. The cognitive radio layer will monitor the network's wireless spectrum usage in real time, providing a foundation for subsequent spectrum resource auctions. The blockchain spectrum trading layer will facilitate spectrum transactions and confirmation.

[0077] Example 3:

[0078] A device for a spectrum auction and trading method based on blockchain and quantum encryption includes a memory, a processor, and a computer program stored within the device and executable on the processor. When the processor executes the program, it implements the spectrum auction and trading method based on blockchain and quantum encryption. The device can be used independently or in conjunction with a computer. Quantum encryption steps are proposed, allowing for integration with available quantum equipment where possible, and also incorporates future scalability.

[0079] To sum up, the purpose of the present invention is to provide a system that can improve the high utilization rate and universality of scarce spectrum resources, while also having the advantages of trusted management of spectrum resources, low transaction confirmation delay, low consensus energy loss of the entire blockchain system, and good scalability.
