Detailed Description

In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.

As one example, in related network communications, communications between devices often require a user to manually send through a control terminal, and communication control between devices is not automated and is inefficient. Moreover, wireless signals are easily intercepted and cracked, and if not taken with sufficient security measures, private information may be revealed or hacked.

In the invention, the intelligent contract and a plurality of devices are deployed in the blockchain network, the execution conditions of the devices are configured in the intelligent contract, for the devices in the blockchain, the first device can acquire the target parameters, if the target parameters meet the target execution conditions of the first device, the communication request aiming at the target parameters is acquired, then the intelligent contract responds to the received communication request, if the identity authentication of the first device is completed, the second device corresponding to the communication request is determined, authentication passing information is sent to the first device, the first device responds to the received authentication passing information, the target parameters are sent to the second device, then the second device executes the device operation corresponding to the target parameters, thereby establishing a decentralised network through the blockchain, realizing the automatic communication control among the devices under the condition that the intelligent closing does not need to trust a third party, enabling the devices to execute the corresponding operation according to the execution conditions of the devices, and improving the convenience of the control among the devices and the efficiency of the communication among the devices. And when the devices communicate, the validity of the data interaction can be verified based on a consensus algorithm, and the consistency of the data on the block chain is ensured, so that the confidentiality and the integrity of the data are ensured, and the utilization rate of network resources is improved.

Referring to fig. 1, a step flow chart of a communication method of a device provided in an embodiment of the present invention is applied to a blockchain network, where an intelligent contract and a plurality of devices are deployed in the blockchain network, where execution conditions of the devices are configured in the intelligent contract, and specifically may include the following steps:

step 101, a first device acquires a target parameter, and if the target parameter meets a target execution condition of the first device, a communication request aiming at the target parameter is acquired;

in the embodiment of the invention, a block chain network can be constructed for corresponding equipment, and each equipment is accessed into the block chain network, so that data interaction can be performed between each equipment based on the block chain network. Optionally, the blockchain network may be applied to an intelligent home scene, and the device may be various home appliances, etc., where it is to be noted that in the embodiment of the present invention, the intelligent home scene is exemplified, and it is to be understood that the present invention is not limited to this, and may also be applied to other internet of things scenes.

In an example, referring to fig. 2, a schematic diagram of a communication architecture provided in an embodiment of the present invention is shown, by constructing a blockchain network, deploying intelligent contracts and consensus algorithms in the blockchain network, and accessing a plurality of devices, thereby establishing a decentralised network through the blockchain, and implementing automatic communication control between devices through intelligent convergence without needing to trust a third party, so that each device can perform a corresponding operation according to its own execution condition, and the convenience of control between devices and the efficiency of communication between devices are improved. And when the devices communicate, the validity of the data interaction can be verified based on a consensus algorithm, and the consistency of the data on the block chain is ensured, so that the confidentiality and the integrity of the data are ensured, and the utilization rate of network resources is improved.

In a specific implementation, a decentralised network (i.e. a blockchain network) can be established through a blockchain technology, all devices are connected in the blockchain network, all connected devices are registered in the blockchain network at the same time, unique identification IDs and communication authorities are allocated to each device, corresponding intelligent contracts are deployed at the same time, terms and execution conditions of a communication protocol between the devices are configured in the intelligent contracts, each device generates data and transmits the data based on the terms, and performs corresponding operations, such as data interaction with other devices, execution target operations and the like, when the execution conditions are met, so that the communication between the devices in the blockchain network can be automatically controlled through the intelligent contracts by configuring the corresponding terms and the execution conditions of the devices in the intelligent contracts, and confidentiality and integrity of the communication between the devices are ensured.

When the device is added into the blockchain network, the identity of the device can be authenticated in a digital identity authentication mode based on the blockchain network so as to verify the legitimacy of the device. For example, in a smart home scenario, assuming devices include door locks, routers, air conditioners, refrigerators, washing machines, switches, televisions, lights, purifiers, humidifiers, and central control devices, etc., a blockchain network for these pieces of furniture may be constructed and each piece of furniture is assigned a unique identification ID and communication rights, including "door locks", "routers", "air conditioners", "refrigerators", "washing machines", "switches", "televisions", "lights", "purifiers", "humidifiers", and "central control devices", etc., as each piece of furniture accesses the blockchain network.

As for the communication authority, it may be a communication activity range and limitation that the device may perform in the blockchain network, including data transceiving authority, data access authority, network resource usage authority, pairing and communication authority, and the like. The data receiving and transmitting rights may be data receiving and transmitting rights, for example, a part of devices only have data transmitting rights but not data receiving rights, a part of devices only have data receiving rights but not data transmitting rights, a part of devices simultaneously have data transmitting rights and data receiving rights, and the like; the data access right item can be the right of the device to access the data service stored in the blockchain network, including the data reading right, the data writing right, the data deleting right and the like, for example, the sensor device generally only has the writing right and is used for reporting the state parameter of the sensor itself and cannot perform other operations, the intelligent sound has the data reading right and the data writing right and can read the states of other devices so as to control the device, and the central control device can have the data reading right, the data writing right, the data deleting right and the like so as to control the other devices; the network resource usage rights can be rights of using network resources by devices, such as broadband usage amount, connection frequency, etc., for example, a router can control bandwidth usage of each device according to device type of the device, so as to ensure that devices such as televisions have enough bandwidth, or control whether new devices access to a blockchain network, etc.; the pairing and communication authority can be whether the equipment can directly communicate with other equipment or exchange data and the like, and the pairing and the peer-to-peer can be carried out with other equipment at corresponding time, for example, a door lock and the like can only accept control commands of authorized equipment, so that the instruction source is ensured to be reliable, the equipment can only be paired with authenticated equipment after reset, malicious operation is prevented, and therefore, the equipment is classified and managed through configuring corresponding communication authority of the equipment in an intelligent contract, and the flexibility and convenience of automatic control of the equipment are improved.

In addition, besides the intelligent contracts, a corresponding consensus algorithm can be configured in the blockchain network for verifying the correctness of communication data between devices, and the processing procedure based on the intelligent contracts and the consensus algorithm can comprise the following steps:

1. node selection: the consensus algorithm can automatically select the equipment nodes participating in network communication, and automatically adjust the weight and contribution of the nodes according to the credibility and performance of the nodes.

2. And (3) condition judgment: the conditions are preset in advance in the intelligent contract, and the automatic judgment can be performed after the conditions are met. In network communication, whether the communication conditions are met or not can be automatically judged according to the identities and the authorities of the two communication parties, and the functions of identity verification, authority verification and the like between equipment and a control end in the Internet of things network are realized.

3. Automatic execution: and automatically executing the set clause content after the preset conditions are met. In network communication, the intelligent contract can automatically execute operations such as encryption, decryption, signature and the like, so that human intervention and misoperation are avoided, and the working efficiency is improved.

4. And (3) data verification: the intelligent contract can verify the communication data of the equipment network according to the terms of the communication protocol in the contract, so that the data is prevented from being tampered and forged. The consensus algorithm can ensure the authenticity and the integrity of communication data, and can automatically synchronize the data in different equipment nodes, thereby avoiding the occurrence of inconsistent and lost data.

5. Automatic notification: the intelligent contract can automatically inform the wireless network communication parties of the actual communication conditions, such as communication success, failure, overtime and the like, so that the transparency and reliability of the wireless network communication of the equipment are improved, and the occurrence of communication failure and misunderstanding is avoided.

In some possible implementations, the intelligent contract may obtain the device reputation and the device parameters of each device, and then perform device evaluation on the device according to the device reputation and the device parameters to obtain the weight information and the contribution degree of the device. Wherein the weight information is used to characterize a degree of importance of the device in the blockchain network, and the contribution degree is used to characterize a degree of contribution of the device in the blockchain network.

Wherein, the measurement of the credibility at least can comprise: history of performance: the past performance of the device in the blockchain network, such as the number of successful communication, the availability of service, whether malicious behavior exists, etc.; resource contribution: the equipment provides resources such as computing power, storage space, bandwidth and the like for the blockchain network; degree of participation: the frequency and duration of device activity in the blockchain network, online participation in the duration of activity, and the like. Optionally, the weight of a device refers to the relative importance or influence of the device in the blockchain network, and the contribution degree refers to a measure of the contribution of the device in the blockchain network to the stabilization of the blockchain network. The weighting and contribution adjustment of devices may be dynamically adjusted according to a particular algorithm, e.g., a child device may get higher weight if it is able to reliably process and forward data, and thus the role of the device in the blockchain network may be more important. Also, if a device frequently participates in data processing or other blockchain network activities, its contribution increases, and may therefore get more incentive, such as more blockchain network service requests or higher service priorities.

In another possible implementation manner, the condition judgment and automatic execution are performed, by configuring a corresponding execution condition for each device in the intelligent contract, the device itself detects and judges a corresponding state parameter, and if the execution condition is met, a corresponding operation is performed. Wherein, the execution conditions at least can include: 1. identity authentication requirements: defining how the device verifies the identity; 2. access control rules: specifying which devices have access to a particular network resource; 3. data sharing policy: deciding which data can be shared, and how; 4. quality of service standard: ensuring that the data transmission meets specific time delay and reliability requirements; 5. security and privacy protection: the method comprises the steps of data encryption, anonymization requirements and the like, and operation rules can be set for equipment and services in a blockchain network through execution conditions, so that automatic execution condition judgment is realized.

In one example, for sensor furniture, corresponding condition parameters can be set, when the environmental parameters collected by the sensor meet the condition parameters, the reporting of the environmental parameters, the adjustment instruction and the like can be triggered so as to transmit the environmental parameters to the corresponding furniture, and corresponding operations are performed by the corresponding furniture, for example, when the temperature sensor detects that the environmental temperature reaches 28 degrees, the corresponding temperature parameters and the adjustment instruction can be transmitted to the air conditioner so as to cool the air conditioner, thereby establishing a decentralised network through a blockchain, and realizing automatic communication control among devices through intelligent integration under the condition that a third party is not required to be trusted, so that each device can perform corresponding operations according to own execution conditions, thereby improving the convenience of control among the devices and the efficiency of communication among the devices.

In another example, the process of condition judgment may also be: detecting a communication request in a block chain network, automatically judging whether the communication request meets a preset condition, if so, allowing the communication request to be automatically executed, otherwise, preventing the communication request, and simultaneously, after the communication is completed, recording corresponding communication activity information by an intelligent contract.

In some possible implementations, for a process that the device performs automatic execution according to an execution condition, assuming that a first device located in the blockchain network is located, after a corresponding target parameter is collected, the target parameter may be compared with a target execution condition corresponding to the first device, and if the target parameter meets the target execution condition, a communication request for the target parameter may be obtained, so as to initiate communication with other devices, so as to implement processing of the target parameter. The target parameter may include a state parameter of the target device itself, an environmental parameter of the environment, and the like, and the environmental parameter may include at least one of an environmental temperature, an environmental humidity, illumination information, air information, and a smoke parameter, for example.

In a specific implementation, a first device collects environmental parameters of an environment in which the first device is located; if the environment parameter meets the target execution condition of the first device, selecting a second device associated with the environment parameter from a plurality of devices, and then generating a communication request aiming at the second device so as to send the communication request to the intelligent contract, and carrying out identity verification on the first device by the intelligent contract to judge whether the first device belongs to legal devices in the blockchain network.

For example, assuming that the first device is a temperature sensor, the temperature sensor may collect an ambient temperature in real time, and compare the collected temperature with a preset temperature set in an execution condition, including comparing with a heating temperature threshold, comparing with a cooling temperature threshold, and the like, and when the corresponding condition is satisfied, may send the temperature to an air conditioner so that the air conditioner performs cooling or heating, and the like; assuming that the first device is a humidity sensor, the humidity sensor may collect ambient humidity in real time, compare the collected humidity with preset humidity set in an execution condition, determine whether humidification or dehumidification is required for the environment, if it is determined that humidification is required, send corresponding humidity and a humidification instruction to the humidifier so as to humidify the humidifier, and if it is determined that dehumidification is required, send corresponding humidity and a dehumidification instruction to the air conditioner so as to dehumidify the environment.

Step 102, the intelligent contract responds to the received communication request, if the identity authentication of the first device is completed, the second device corresponding to the communication request is determined, and authentication passing information is sent to the first device;

After the first device sends the communication request to the intelligent contract, the intelligent contract can respond to the received communication request, if the identity authentication of the first device is completed, the second device corresponding to the communication request is determined, authentication passing information is sent to the first device, and therefore whether the first device is legal in the blockchain is judged through identity authentication of the first device, and the safety of communication between the devices is guaranteed.

In some possible implementations, the smart contract may acquire a first device identity and a first communication right of the first device, and if the first device identity indicates that the first device is already in a registration state in the smart contract and the first communication right indicates that the first device has a right to communicate with other devices, determine a second device corresponding to the communication request, and acquire a current running state of the second device; if the second equipment is in a standby state currently, the intelligent contract sends authentication passing information for the communication request to the first equipment; if the second device is currently in an operating state, the intelligent contract sends authentication failure information for the communication request to the first device.

For each device in the blockchain network, when the network is accessed, corresponding registration is required, only the registered device can communicate with other devices in the blockchain network, after the intelligent contract receives a communication request of the first device, whether the first device belongs to the device registered in the blockchain network can be verified, if the first device belongs to the registered device, whether the first device has permission to communicate with other devices can be further judged, if the corresponding communication permission is also provided, a second device which needs to be communicated by the first device can be determined, and the current running state of the second device is acquired so as to detect whether the second device is in a standby state currently, if the second device is in the running state currently, the second device is characterized in that other task operations are currently being executed by the second device, tasks corresponding to the first device cannot be executed, the intelligent contract can send authentication failure information to the first device so as to inform the first device that the second device is in a busy state and retried later, and the like; if the second device is currently in a standby state, representing that the second device is currently in an idle state, and executing a task corresponding to the first device, the intelligent contract can send authentication passing information to the first device, and inform the first device that the first device can communicate with the second device, so that the first device performs data interaction with the second device based on a secure channel in the blockchain.

Step 103, the first device sends the target parameter to the second device in response to receiving the authentication passing information;

in the embodiment of the invention, if the first device receives the authentication passing information sent by the intelligent contract, the target parameter can be sent to the second device based on the secure channel in the blockchain network, so that the second device executes corresponding operation based on the target parameter; if the first device receives the authentication failing information sent by the intelligent contract, a corresponding communication request can be initiated to the intelligent contract again after a preset time interval, so that whether the intelligent contract meets the communication condition or not can be detected again.

And 104, the second device executes the device operation corresponding to the target parameter.

As before, assuming that the target parameter is an environmental parameter, the environmental parameter may include at least one of an environmental temperature, an environmental humidity, illumination information, air information, and a smoke parameter, and the corresponding second device is different based on the different environmental parameter, for example, the second device may include one of an air conditioner, a humidifier, a purifier, a lamp, a sun-shading furniture, and a smoke alarm, and the air conditioner performs a temperature adjustment operation corresponding to the environmental temperature; and/or the humidifier performs a humidity adjustment operation corresponding to the ambient humidity; and/or the purifier performs an air conditioning purifying operation corresponding to the air information; and/or the lamps or the sun-shading furniture execute illumination adjustment operation corresponding to the illumination information; and/or the smoke alarm executes smoke alarm operation corresponding to smoke parameters, thereby establishing a decentralised network through a blockchain, realizing automatic communication control among devices under the condition that a third party is not required to be trusted through intelligent integration, enabling each device to execute corresponding operation according to own execution condition, and improving the convenience of control among devices and the efficiency of communication among devices.

In addition, after the second device executes the corresponding operation, the execution state record aiming at the target parameter can be sent to the intelligent contract in response to the device operation corresponding to the target parameter after the execution is finished, the intelligent contract broadcasts the execution state record, and each device synchronizes the execution state record, so that the intelligent contract synchronizes the data generated by the communication between the first device and the second device to other devices based on the consensus algorithm, the consistency of the data in the blockchain network is ensured, and each device can synchronize the corresponding data so as to improve the effectiveness of device control in the blockchain network.

In a specific implementation, the intelligent contract performs validity verification on the execution state record, if the execution state record is valid, the execution state record is packaged into a candidate block, then the candidate block is broadcast into the blockchain network, then other devices except the first device and the second device respond to the detection of the candidate block to perform validity verification on the candidate block, and if the candidate block passes the verification, the candidate block is added into the local blockchain copy.

In one example, for a data synchronization process between devices, it may include:

1. And (3) data generation: when the device collects data (e.g., sensor readings), it generates a record of the communication request and broadcasts the record to the network.

2. Request verification: other devices receiving the request will verify the validity of the request, including checking the signature, format, and compliance of the data with preset conditions.

3. Block structure: once the requests are validated, they are packed into a candidate block. A device or group of devices may be responsible for this packing process according to rules of the consensus algorithm.

4. Block broadcasting: the device that created the new block broadcasts it to the network, and after receiving this new block, the other devices will verify, ensuring that all requests therein are legitimate and that the block itself meets the requirements of the consensus algorithm.

5. And (3) consensus is achieved: once a block is verified as correct, other devices add this block to their own blockchain copy. This process means that devices in the network agree on the current state of the blockchain.

6. Data synchronization: as new blocks are added, the local blockchain copy of the device is updated, thereby synchronizing the latest requested data contained in the blocks. This ensures that each device in the network has a consistent view of the data.

7. Continuous synchronization: the internet of things device will continuously generate data and these data will continuously enter the network through new requests, be packed into blocks, and be verified and added to the blockchain through the consensus process. This looping process ensures that data in the network continues to be synchronized.

In addition, before data interaction, the devices in the blockchain network can be verified to verify whether the identity of the opposite party is legal, and the corresponding verification process can be as follows:

and (3) data receiving: and receiving the data in the network, and decrypting the data by using the corresponding key according to the agreement clause.

Signature verification: the receiving device uses the public key of the sending device to verify the authenticity of the data signature, and if the verification passes, the data source is normal and the data source is not tampered in the transmission process.

Recording and auditing: all communication requests and results are recorded in the blockchain network for auditing and analysis.

It should be noted that the embodiments of the present invention include, but are not limited to, the foregoing examples, and it will be understood that those skilled in the art may also set the embodiments according to actual requirements under the guidance of the concepts of the embodiments of the present invention, which are not limited thereto.

In order to enable those skilled in the art to better understand the technical solutions according to the embodiments of the present invention, the following description is given by way of example:

Two devices: device a (intelligent temperature sensor) and device B (intelligent air conditioning system). Device a is responsible for monitoring room temperature and communicating with device B under certain conditions to adjust temperature. The following is an example flow of automated condition judgment and communication execution:

step 1: setting intelligent contract clauses:

deploying an intelligent contract on the blockchain, the contract comprising the following terms:

if the temperature detected by device a exceeds 24 ℃, communication with device B is triggered. Both device a and device B must have valid registration and authentication states in the blockchain network. Device B must be on standby, that is, without other tasks being performed, upon receipt of a communication request from device a.

Step 2: condition judgment of the equipment A:

device a periodically detects room temperature and compares the readings to a threshold (24 ℃) defined by the smart contract. If the temperature exceeds the threshold, device A is ready to initiate communication.

Step 3: identity verification and rights checking:

device a sends a request to the smart contract over the blockchain network containing its device ID and the detected temperature value. The smart contract verifies the identity and status (registration and authentication status) of the device a and checks whether the device B is in a standby state.

Step 4: communication is performed:

if the status of both device A and device B satisfy the conditions of the smart contract, the contract automatically performs the communication operation:

the intelligent contract instructs the device A to send the information of the temperature exceeding to the device B.

Device a sends a signal to device B using a secure channel of the blockchain network, the signal possibly including the current temperature and the proposed adjustment instructions.

And after the equipment B receives the signal, adjusting the air conditioner setting according to the received information so as to reduce the indoor temperature.

Step 5: communication status feedback:

after the device B finishes executing, an execution state report is sent to the intelligent contract to confirm that the temperature is adjusted according to the instruction.

The smart contract records the results of this communication and updates the status of device a and device B on the blockchain.

Step 6: data verification and synchronization:

the consensus algorithm ensures that all network nodes (including device a and device B) have a record of this communication, ensuring consistency and non-tamper ability of the data.

If communication fails or device B is busy, the smart contract may record a failure event and may trigger a warning or retry mechanism.
