Before formally introducing the device linkage method and the blockchain network provided by the embodiment of the present application, the operation environment of the embodiment of the present application is simply introduced, where a blockchain is a decentralized distributed database system where all nodes in the blockchain network participate in maintenance together, and is composed of a series of data blocks generated based on a cryptography method, and each data block is a block in the blockchain. The blocks are linked together in order according to the chronological order of the generation times, forming a chain of data, which is referred to visually as a chain of blocks. The blockchain has the security characteristics of being unchangeable, unforgeable and completely traceable due to the special blockchain and the transaction generation and verification protocol. Some concepts of blockchain networks are presented below.
Nodes in the blockchain network may be referred to as blockchain nodes, wherein the blockchain network is based on a P2P (Peer-to-Peer) network, and each P2P network node participating in transaction and storing, verifying and forwarding the blockchain is a node in the blockchain network. Each node participating in the blockchain network can synchronize all data on the current blockchain, so that a plurality of copies of the blockchain data are stored to a plurality of nodes on the blockchain
The user identity in the blockchain can be represented by using a public key or an account address generated according to the public key, and the public key and the private key appear in pairs, wherein the private key is held by the user and is not published in the blockchain network, and the public key or the account address can be freely published in the blockchain network. The public key may be an account address through a specific hash and encoding. It is worth mentioning that the user identity and the block link point do not have a one-to-one correspondence, and the user can use the private key of the user on any block link node.
Data writing to a blockchain is achieved by a blockchain link point issuing a "Transaction" to the blockchain network. The transaction comprises the signature of the user on the transaction by using the private key of the user so as to prove the identity of the user. Transactions are recorded into the generated new blockchain by miners (blockchain nodes performing blockchain consensus competition mechanisms), then are issued to the blockchain network, and are verified by other blockchain nodes and accepted, and then transaction data are written into the blockchain.
In the embodiment of the present disclosure, in order to protect data in a blockchain network, role differentiation and permission setting are performed on different nodes, so that permissions of the different nodes in the aspects of accessing a blockchain, data on a synchronization blockchain, accessing data in the blockchain, and the like are different.
Referring to fig. 1, a block chain network according to an embodiment of the present disclosure is shown. Each node in the block chain network is configured with an account, and different accounts have different roles and permissions, so that the nodes of the block chain network have the roles and permissions corresponding to the accounts. Through a block chain network, a credible equipment intercommunication and interconnection platform with multiple Internet of things platforms is established, all the Internet of things platforms exchange user, equipment information and communication protocols, and simultaneously user data and private protocols of all manufacturers are not required to be disclosed, so that the problem of Internet of things equipment intercommunication and interconnection among all the Internet of things platforms is solved. The platform credit endorsement based on the block chain is characterized in that each Internet of things platform participates as a consensus node, the intercommunication interconnection protocol achievement of the sharing platforms can be fair, the positions among the Internet of things platforms are equivalent, the intercommunication interconnection of different Internet of things platform devices is realized through the mode, and the intelligent life is better experienced through linkage of the devices of the different Internet of things platforms. If the air conditioner of the first Internet of things platform, the purifier of the second Internet of things platform and the humidifier of the third Internet of things platform are purchased at home, when the air quality is poor, the air conditioner of the first Internet of things platform can be linked with the humidifier of the second Internet of things platform and the humidifier of the third Internet of things platform.
In connection with fig. 1, for example, a first node in a blockchain network sends to a second node a linkage request from a first device under the first node that is bound to a user, the linkage request including: the device information of the second device, the user identity of the user and the identity information of the first node which need to be linked and are located under the second node. Vividly, this first node can regard as thing networking platform one, and correspondingly, this first equipment can be the air conditioner, and the second node can regard as thing networking platform two, and correspondingly, this second equipment can be the clarifier. It can be understood that the second node may be regarded as the internet of things platform three, and correspondingly, the second device may be a humidifier. As an implementation manner, when a trigger condition for linking a second device is satisfied, a first device sends a linkage request to a first node, the first node determines a node corresponding to the second device, such as a second node, from an intelligent contract written in a block chain network, and then sends the linkage request to the second node. As another optional implementation, the first node may receive the device parameter from the first device, determine whether the triggering condition of the linkage second device is satisfied according to the device parameter, determine, when it is determined that the device parameter satisfies the triggering condition of the linkage second device, that the node corresponding to the second device is the second node from the intelligent contract, and send the linkage request to the second node.
When receiving the linkage request sent by the first node, the second node judges whether the equipment information and the identity information are written into an intelligent contract of the block chain network, and when the equipment information and the identity information are written into the intelligent contract of the block chain network, the second node judges whether the equipment information and the user identity are in a binding relationship; and when the device information and the user identity are determined to be in a binding relationship, sending the linkage request to the second device so that the second device executes the operation corresponding to the linkage request.
As an optional implementation manner, when determining that the device information and the identity information are written in an intelligent contract of the blockchain network and that the device information and the user identity are in a binding relationship, the second node further determines whether the first node has obtained a private key corresponding to the public key of the first node, and when determining that the first node has obtained the private key corresponding to the public key of the first node, sends the linkage request to the second device, so that the second device executes an operation corresponding to the linkage request. As an optional implementation manner, when confirming whether the first node has obtained the private key corresponding to the public key of the first node, the second node may send verification information to the first node; receiving a first digital signature obtained by the first node after the first node digitally signs the verification information according to the private key of the first node; verifying the first digital signature according to the public key of the first node, wherein the public key of the first node is obtained from the identity information of the first node; and when the first digital signature is verified, the first node is represented to obtain a private key corresponding to the first node public key.
As another implementation, when the second node determines whether the first node has obtained the private key corresponding to the public key of the first node, the second node may also send verification information to the first node; receiving a second digital signature obtained by a first node performing digital signature on generated information to be verified according to a private key of the first node, wherein the information to be verified is generated by the first node according to a preset information generation rule, and the information generation rule is preset in the first node and the second node; verifying whether the information to be verified is generated according to the information generation rule; when the verification information is generated according to the information generation rule, verifying the second digital signature according to the public key of the first node; and when the second digital signature is verified, confirming that the first node obtains a private key corresponding to the public key of the first node.
It should be noted that each node shown in fig. 1 may include a plurality of devices from the same vendor.
It should be noted that, in the embodiment of the present application, the making of the intelligent contract is made jointly through a plurality of internet of things platforms, so that the fairness of the protocol is ensured. That is, the update and the revocation of the intelligent contract are initiated by one party, the other parties participate in consensus as voting parties, if all the parties agree, the modification and the revocation are effective, and if the parties are different, the failure is caused. Taking the first node as an example, the first node sends a modification request for the intelligent contract to all nodes except the self node in the block chain network, and all the other nodes include the second node; then receiving feedback information of each node in all the other nodes based on the modification request; then determining that each of the remaining all nodes approves the modification request based on the feedback information; and when each node in all the other nodes agrees with the modification request, updating the intelligent contract.
It should be noted that the user registers on the platform, and then the user identity is mapped to the blockchain registered user through the intelligent contract. The method and the system ensure the one-to-one correspondence between the original Internet of things user identity and the block chain registration user identity, protect sensitive information of the user from being leaked, and find the corresponding relation on the chain through the user identity. If the user registers on a plurality of Internet of things platforms, only one registered user on the block chain can be ensured. The user identification can be identification card information or a telephone number.
The equipment is registered on an original internet of things platform, and then the equipment information is mapped into block chain registration equipment through an intelligent contract. The method and the system ensure the one-to-one correspondence between the original Internet of things equipment information and the block chain registration equipment information, protect sensitive information of the equipment from being leaked, and find the corresponding relation on the chain through the equipment information. If the equipment is registered on a plurality of Internet of things platforms, only one registered equipment on the block chain can be ensured. The device information may be a MAC Address (Media Access Control Address) or an SN code (Serial Number).
It should be noted that the user and the device are bound by performing relationship with the original internet of things platform, and the internet of things platform synchronizes the device information and the user information to the block chain through an intelligent contract while binding. For example, if li four purchases equipment under different internet of things platforms, for example, an air conditioner of the first internet of things platform, a purifier of the second internet of things platform, and a humidifier of the third internet of things platform are purchased at home, li four can apply for the binding relationship between itself and the air conditioner to the first internet of things platform, also can apply for the binding relationship between itself and the purifier to the second internet of things platform, and also can apply for the binding relationship between itself and the humidifier to the third internet of things platform. During linkage, only equipment bound by the same user can be linked, and equipment bound by other people cannot be linked, namely the Lifours can only be linked among a plurality of pieces of equipment bound with the Lifours, but cannot be linked with the Zhang-Sanjian equipment.
Referring to fig. 2, steps included in a method for linking devices in the blockchain network shown in fig. 1 according to an embodiment of the present invention will be described with reference to fig. 2.
Step S101: the first node sends a linkage request from a first device bound with a user under the first node to the second node.
A first node in the blockchain network sends a linkage request from a first device bound with a user under the first node to a second node in the blockchain network, for example, the first node sends a linkage request from an air conditioner bound with liqi under the first node to the second node. Wherein the linkage request comprises: the device information of the second device (such as the device information of the humidifier) which needs to be linked and is located below the second node, the user identity (such as the user identity of lee, which may be a mobile phone number, an identity card, etc.) of the user, and the identity information of the first node. As an implementation manner, when a trigger condition (for example, when the air conditioner temperature is higher than 30 degrees, which is a trigger condition) for linking the second device is satisfied, the first device may send a linking request to the first node, the first node determines a node, such as the second node, corresponding to the second device from the intelligent contract written in the blockchain network, and then sends the linking request to the second node. As another optional implementation, the first node may receive the device parameter from the first device, determine whether the triggering condition of the linkage second device is satisfied according to the device parameter, and when it is determined that the device parameter satisfies the triggering condition of the linkage second device, determine, from the intelligent contract, that the node corresponding to the second device is the second node, and send the linkage request to the second node.
Step S102: and the second node judges whether the equipment information and the identity information are written into an intelligent contract of the block chain network.
After receiving the linkage request sent by the first node, the second node first determines whether the device information and the identity information carried in the linkage request are written into the intelligent contract of the block chain network, if so, step S103 is executed, and if not, the process is not performed or ended.
Step S103: if so, the second node judges whether the equipment information and the user identity are in a binding relationship.
When it is determined that the device information and the identity information are written in the intelligent contract of the block chain network, the second node further determines whether the device information and the user identity are in a binding relationship, if so, step S104 is executed, and if not, the processing is not performed or ended. It should be noted that, during linkage, only the devices bound by the same user can be linked, and the devices bound by other users cannot be linked, that is, lie iv can only be linked with a plurality of devices bound with itself, but cannot be linked with the devices bound by zhang san.
Step S104: if yes, the second node sends the linkage request to the second equipment so that the second equipment can execute the operation corresponding to the linkage request.
And when the equipment information and the user identity are determined to be in a binding relationship, the second node sends the linkage request to the second equipment so that the second equipment executes the operation corresponding to the linkage request. For example, the second node sends the linkage request to the humidifier, so that the humidifier performs an operation corresponding to the linkage request, such as turning on the humidifier.
As another alternative implementation, as shown in fig. 3, for a device linkage method applied to the blockchain network shown in fig. 1 according to an embodiment of the present invention, steps included in the method will be described below with reference to fig. 3.
Step S201: the first node sends a linkage request from a first device bound with a user under the first node to the second node.
This step is the same as step S101 described above, and may be referred to each other.
Step S202: and the second node judges whether the equipment information and the identity information are written into an intelligent contract of the block chain network.
This step is the same as step S102 described above, and may be referred to each other.
Step S203: if so, the second node judges whether the equipment information and the user identity are in a binding relationship.
This step is the same as step S103 described above, and may be referred to each other.
Step S204: if so, the second node confirms that the first node has obtained a private key corresponding to the first node's public key.
And when the device information and the user identity are determined to be in a binding relationship, the second node confirms that the first node obtains a private key corresponding to the public key of the first node.
As another embodiment, when the second node confirms whether the first node has obtained the private key corresponding to the public key of the first node, the process may be described with reference to the steps described in fig. 4.
Step S301: the second node sends authentication information to the first node.
And when the second node determines that the equipment information and the user identity are in a binding relationship, the second node sends verification information to the first node, so that when the first node receives the verification information sent by the second node, the first node carries out digital signature on the verification information according to a private key of the first node to obtain a first digital signature, and sends the first digital signature to the second node.
Step S302: and the second node receives a first digital signature obtained by the first node after the first node carries out digital signature on the verification information according to the private key of the first node.
Step S303: and the second node verifies the first digital signature according to the public key of the first node.
After receiving a first digital signature sent by a first node, a second node verifies the first digital signature according to a public key of the first node. When the first digital signature is verified, the first node is represented to obtain a private key corresponding to the first node public key. Wherein the public key of the first node is obtained from the identity information of the first node.
As another optional implementation, when determining whether the first node has obtained the private key corresponding to the public key of the first node, the second node may also send verification information to the first node, so that when receiving the verification information, the first node generates information to be verified according to a preset information generation rule, performs a digital signature on the generated information to be verified according to the private key of the first node to obtain a second digital signature, and sends the second digital signature to the second node. When receiving a second digital signature obtained by a first node performing digital signature on generated information to be verified according to a private key of the first node, a second node verifies whether the information to be verified is generated according to the information generation rule, and when the verification information is generated according to the information generation rule, the second node verifies the second digital signature according to the public key of the first node; and when the second digital signature is verified, confirming that the first node obtains a private key corresponding to the public key of the first node. The information to be verified is generated by the first node according to a preset information generation rule, and the information generation rule is preset in the first node and the second node.
Step S205: and the second node sends the linkage request to the second equipment so that the second equipment executes the operation corresponding to the linkage request.
This step is the same as step S104 described above, and may be referred to as follows.
Further, the method comprises: the first node sends a modification request aiming at the intelligent contract to all other nodes except the self node in the block chain network, wherein all other nodes comprise the second node; the first node receives feedback information of each node in all the other nodes based on the modification request; the first node determining, based on the feedback information, that each of the remaining all nodes approves the modification request; the first node updates the intelligent contract. The process represents an updating process of the intelligent contract, and it should be noted that the updating and the revocation of the intelligent contract are initiated by one party, the other parties participate in consensus as voting parties, if all the parties agree, the modification and the revocation are effective, and if the parties are different, the modification and the revocation are failed.
In the embodiment of the application, the equipment intercommunication interconnection protocol is realized through the intelligent contract disclosed on the chain, and the safety of the intelligent contract can be ensured. The intelligent contract is established through a plurality of internet of things platforms, and fairness of the protocol is guaranteed.
