An embodiment of the present disclosure provides an intelligent spectrum sharing system, referring to fig. 1, fig. 1 is a schematic diagram of intelligent spectrum sharing according to an embodiment of the present disclosure, including:
The embodiment of the disclosure provides an intelligent spectrum sharing system, which comprises:
A user node 110, a plurality of AP (WIRELESS ACCESS points ) nodes 120, wherein the user node 110 and at least two target AP nodes 120 of the plurality of AP nodes 120 have signed an intelligent contract, and the intelligent contract includes a first private key and a first public key for encrypting and decrypting data of the user node 110; the frequency spectrum of the different AP nodes 120 is different;
The user node 110 is configured to obtain a first private key from the intelligent contract, encrypt, based on the first private key, first data to be transmitted to itself to obtain second data, and send the second data; wherein the first private key is determined based on the first public key and identity information of the user; the first public key is determined based on identification information of a target operator, which is an operator that is allowed to access data of the user node 110;

The user node and the plurality of AP nodes sign an intelligent contract, and the user is not limited to sign an intelligent contract with only one AP node through the intelligent contract, and mutual trust among the AP nodes can be realized based on the intelligent contract, so that spectrum sharing among the AP nodes is realized, and idle spectrum resources can be more fully utilized. Moreover, for the data to be transmitted by the user node, the data to be transmitted by the user node is encrypted and decrypted through the first private key and the first public key, and not all the AP nodes can acquire the first public key, but the user node firstly prescribes an operator which allows access to the data, and only if the operator to which the AP node belongs is the operator which allows access to the data of the user node, the AP node can acquire the first public key from the intelligent contract, further decrypt the second data based on the first public key and acquire the data transmitted by the user node, so that the privacy protection of the data of the user node is realized, and the security of the data is improved.
The user node may establish an intelligent contract with a plurality of target AP nodes, where the contract items included in the intelligent contract include whether the spectrum of each target AP node 120 is greater than a preset spectrum threshold; whether the balance of the user node is greater than a preset balance threshold; and the identification information of the operator to which the target AP node belongs. If the above conditions are satisfied, the target AP node may provide a frequency band for the user node based on its own frequency spectrum, where the target AP node provides the frequency band for the user node as a frequency band in the own frequency spectrum of the target AP node, so that the user node may trade with multiple AP nodes, and each AP node may dynamically share and use the licensed spectrum owned by each AP node through the blockchain network.
In order to realize the privacy protection of the data of the user node, the security of the data is improved. The AP node which signs an intelligent contract with the user node can only acquire the data transmitted by the user node by the AP node which allows the data to be accessed, specifically, the identity information of the user can be written into a blockchain, wherein the identity information of the user comprises the identity of the user, the balance of the user and the like; after the intelligent contract is signed, the intelligent contract can acquire the identity information of the user from the blockchain, the user allows access to the information of the operator of the AP of the data, specifically, the information of the operator can be any one of the identification information of the operator, then a first public key is generated based on the information, a first private key is generated based on the first public key and the identity information of the user, and for each AP node, whether the operator of the AP stage is the operator of the AP of which the access to the data is allowed or not is judged, and if so, the first public key is sent to the AP node. When the user node transmits data by utilizing the frequency spectrum allocated to the user node, the user node performs data signature on first data to be transmitted through a first private key to acquire an AP node of the first public key, and the encrypted data can be decrypted by utilizing the first public key, so that the content transmitted by the user is acquired.
In a possible embodiment, the user node 110 is further configured to send a first access request to the first target AP node 120;
The first target AP node 120 is configured to determine whether to allow the user node 110 to access after the first access request passes authentication; if so, authorizing the user node 110 to use its own spectrum communication, and distributing a second public key and a second private key for communication connection to the user node 110; transmitting the second private key to the user node 110, and writing the second public key to a blockchain network;

When the intelligent contract is built, the user node firstly sends a first access request to the first target AP node, then the first target AP node firstly authenticates the first access request, after the first access request passes, the first target AP node judges whether the user node is allowed to access or not, if so, the user node is authorized to use the self spectrum communication, a second public key and a second private key for communication connection are distributed to the user node, the second private key is sent to the user node, the second public key is written into the blockchain network, so that the user node can communicate based on the second private key and the second public key when the blockchain network communicates, the specific first target AP node can inform the second private key to the user node in an encrypted mode, and then the second public key is written into the blockchain network in a broadcasting mode.
When the user node sends a second access request to a second target AP node, the second access request is digitally signed based on a second private key, the second target AP node firstly inquires a second public key in the blockchain network in response to the second access request, verifies the second access request based on the second public key, and judges whether the user node is allowed to access or not under the condition that the user node passes the verification; if so, the user node is authorized to use its own spectrum communication, wherein the number of second target AP nodes may be plural. Thus, each AP node can dynamically share and use the authorized spectrum owned by each AP node through the blockchain network.
In a possible embodiment, the AP node 120 is configured to establish a smart contract for the user node 110, the first target AP node 120, and the second target AP node 120, where the smart contract includes a plurality of contract entries, and the contract entries include a first private key, a first public key, and whether a spectrum of the first target AP node 120 is greater than a preset spectrum threshold; whether the spectrum of the second target AP node 120 is greater than a preset spectrum threshold; whether the balance of the user node 110 is greater than a preset balance threshold; identification information of an operator to which the first target AP node 120 belongs; the second target AP node 120 belongs to the operator's identification information.

If the above contract terms are both met, then AP1 and AP2 may provide the user node with spectrum whereby the user transacts with AP1 and AP 2. Specifically, as shown in fig. 3, after the user node signs an intelligent contract with the AP1 and the AP2, the intelligent contract is deployed in the blockchain network, when the user transmits data, the blockchain node performs mining verification according to the intelligent contract, each block confirms the intelligent contract for multiple times for each AP node, and when the intelligent contract is confirmed to pass, the user can utilize the frequency spectrum of the AP node to transmit data.
