Detailed Description
For better understanding of the technical solutions of the present application, the following detailed descriptions of the embodiments of the present application are provided with reference to the accompanying drawings.
It should be understood that the embodiments described are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the examples of this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
The block chain is a special data structure formed by combining the data blocks in a chain mode according to the time sequence, and a decentralized shared general ledger which ensures that data cannot be falsified and cannot be forged is ensured by using a cryptography mode, so that simple data information which has a sequence relation and can be verified can be safely stored. The blockchain technique may utilize an encrypted chained blockchain structure to verify and store data, and a distributed node consensus algorithm to generate and update data.
Fig. 1 is a flowchart of an embodiment of a device registration method based on a block chain according to the present application, and as shown in fig. 1, the device registration method based on a block chain may include:
step 101, in response to any received device registration request, sending the device registration request to any node in a target block chain network, instructing the block chain node to create a registration transaction according to the device registration request, and performing data synchronization with other nodes in the target block chain network, where the device registration request includes a device identification number and device data, and the target block chain network includes multiple nodes.
Specifically, the device registration request may include a device identification number and device data, where the device data may include device-related information, where the device-related information is used to extend various attribute information of a device, and the device may be a component or a product, such as a camera, a door access, or an automobile; the device registration request is used for initiating a request to the blockchain network, and registering device identification and device related data on the blockchain network so as to facilitate management and control of a management party, wherein the management mode can be through system software such as an information processing system, a resource management system or a network management system, and the system software can be integrated in a service processing platform of a blockchain network node.
In a specific implementation, the device identification number may be a globally unique and resolvable digital object identifier, each device identification number may be composed of two parts, one part is a naming authority, the naming authority may be uniformly distributed by the security identifier management and resolution platform, the other part is a local name, the local name may be used to uniquely identify a device under the naming authority, and the naming authority and the local name may be separated by an ASCII character "/", for example, the device identification number may be identified by the following rule:
device identification number: 86.1005.16/DS-7816H-ST0120110527AA, wherein 86.1005.16 is naming authority, and DS-7816H-ST0120110527AA is local naming.
The equipment-related information may be extended information corresponding to the equipment identification number, and the extended information may include an equipment model, a production date, a batch, a production place, warehousing information, a logistics information production information address link, and a product description address link.
Further, the device may further include a pair of keys, i.e., a private key and a public key; the key may be generated through an SM9 key algorithm, the private key may be used to sign the device registration request, and the public key may be published on the blockchain network, so that the blockchain network checks the device registration request after receiving the device registration request.
The blockchain network may include a plurality of blockchain nodes, wherein each blockchain node may be a workstation, a server, or a data processing center; the blockchain nodes may have the same function and the same processing capability, so that each blockchain node can process the registration request of the device.
When the block chain network is created, the block chain nodes may negotiate keys, for example, one of the block chain nodes may first generate a pair of keys, where the keys include a public key and a private key for use by itself, then generate the next pair of keys, and send the keys to one of the block chain nodes until all the block chain nodes have their own keys, thereby completing the key negotiation between all the block chain nodes. The private key is used for signing the registration transaction, and the public key is used for verifying the signature of the signature registration transaction.
Specifically, when the blockchain network receives a registration request of the device, a blockchain node may be randomly selected from the blockchain network, and the blockchain node processes the device data, where the processing may include creating a registration transaction according to the registration request of the device, where the registration transaction is used to write information of the device to be currently registered into the blockchain.
In particular implementations, the registration transaction may include an execution script, for example, the result of the execution of the script may be: the registered transaction number is named as the equipment identification number, and the equipment data is written into the data field of the registered transaction.
After the registration transaction is created, the current blockchain link point may store the registration transaction in a local database, and send the registration transaction group to all other blockchain nodes, and after the other blockchain nodes receive the registration transaction, the other blockchain nodes may also store the registration transaction in their respective local storages, thereby ensuring data synchronization between the blockchain link points.
Further, before the current block link point sends the registration transaction to the rest of the block link nodes, the registration transaction may be signed, and the signature may be performed by a private key of the current block link point.
Further, before the remaining blockchain nodes store the current registration transaction in their respective local storages, it may also be detected whether the registration transaction has been written to the blockchain, specifically, the registration transaction may be retrieved on the blockchain according to the device identification number in the device registration request, if there is a corresponding registration transaction on the blockchain, the device registration request may be stopped, otherwise, the next operation may be performed.
Step 102, identifying any node in the target block chain network as a main node, indicating the main node to arbitrarily extract a registration transaction, and writing the registration transaction into a block chain after the common identification with the rest nodes is achieved.
Specifically, after the synchronization of the registration transaction at each block link point, one block link node may be randomly selected again in the block link network, the block link node is used as a main block link node, and any one registration transaction is extracted from the main block link node and used as the registration transaction of the current block chain to be written in, and the registration transaction is sent to the other block link nodes in a group.
After the other block chain nodes receive the registration transaction of the main block chain node, the script corresponding to the registration transaction can be executed, if the execution is successful, the registration transaction is signed by the private key of the script, and then the signed registration transaction is returned to the main block chain node.
Further, after any one of the other block chain nodes returns the signature registration transaction to the main block chain node, the block chain node may delete the corresponding stored registration transaction to prevent the same registration transaction from being repeatedly written into the block chain.
After the master blockchain node receives the signature registration transactions of the other blockchain nodes, since the public keys of the other blockchain nodes are also disclosed on the blockchain network, similarly, the received signature registration transactions can be checked through the corresponding public keys, and if the signature checks pass, the registration transactions are written into the blockchain. In one implementation, the registration transaction may first generate a corresponding data block, and then write the data block into a block chain. As shown in fig. 2, the block chain structure is a schematic diagram, the block chain is composed of different data blocks, each newly added data block is spliced after the current last data block, and each data block is connected to form a long chain, i.e. the block chain, where each data block represents a registration transaction.
Further, since the master blockchain node receives the signature registration transactions of the other blockchain nodes in sequence, and due to network delay or verification failure, the master blockchain node may receive only part of the signature registration transactions, and in order to take account of the security and efficiency of the system, a threshold value of the number of signatures may be preset, that is, a predetermined number of signatures is reached, and it can be considered that the current transaction is acknowledged by all blockchain nodes when written, that is, a consensus is achieved among all blockchain nodes. In specific implementation, when the master block chain node verifies and signs one signature registration transaction successfully, the signature number can be accumulated, and when the accumulated total number of the signatures reaches a preset number, the signature verification can be stopped, and the current registration transaction can be directly written into the block chain.
Further, after the registration transaction is written into the blockchain, any object may query the device information on the blockchain, where the query may be initiated to the blockchain network, and in a specific implementation, the query may be initiated to any one blockchain node in the blockchain network, where the query includes an identification number of the device, and after any one blockchain node receives the query, the query may be performed according to the device identification number in the query to obtain corresponding device-related information, and send the device-related information to the requester.
Further, since the requesting party may not have complete blockchain data, the authenticity of the device-related information cannot be verified, i.e., it cannot be guaranteed that the obtained device-related information is indeed on the blockchain. In order to prove the authenticity of the device-related information, the block link node may transmit, to the requester, at the same time the device-related information, attestation data for proving the authenticity of the device-related information. In a specific implementation, a merkel tree may be created, as shown in fig. 3, wherein each registration transaction (data block) may be converted into a hash value through a hash operation, for example, H (1) is the hash value of data block 1, so that all data blocks in the block chain may be converted into a hash value. Further, another hash value can be calculated by concatenation of two hash values, for example, as shown in fig. 3, H (9) can be obtained by H (1) and H (2). When the last hash value, for example, H (15), is obtained through layer-by-layer operation, where H (15) is Root, the Root may be regarded as Root data, that is, reference data, so that each requester may store the Root, and after receiving device-related information, the hash value corresponding to the device-related information may be operated with certification data, so as to obtain a piece of Root data, compare the Root data with the Root, and if the Root data is the same as the Root, the device-related information currently obtained is regarded as true, that is, stored in the current block chain. Taking fig. 3 as an example, if the registration transaction 5 and the certification data are received, the certification data and the registration transaction 5 may be subjected to hash operation, where the certification data includes registration transactions 6, H (12) and H (13), the registration transaction 5 corresponds to the hash value H (5), the registration transaction 6 corresponds to the hash value H (6), H (11) may be obtained by splicing H (5) and H (6), H (14) may be obtained by splicing H (11) and H (12), and Root may be obtained by splicing H (13) and H (14), so that the registration transaction 5 may be confirmed on the block chain, thereby ensuring the authenticity of information.
Further, after the current registration transaction is written into the blockchain, a message of successful device registration may be returned to the device registration requester, where the message of successful device registration may be returned by the master node or by another node.
Further, before any blockchain node returns the query information of the equipment to the requesting party, the identity of the requesting party can be verified, wherein the identity verification mode can be an account number and a password, and can also be other forms of identity verification modes; if the identity authentication is passed, the query information of the equipment can be returned to the requesting party, and if the identity authentication is not passed, the information of refusing query or refusing access and the like can be returned to the requesting party; after the query information of the device is returned to the requesting party, the confirmation information of the requesting party can be waited, and if the confirmation information of the requesting party is not received within the preset time, the query information of the device can be retransmitted to the requesting party.
Further, after any device is registered on the blockchain network, an intelligent contract task may be initiated for the device, where the task initiation may be to initiate an intelligent contract request to any node on the blockchain network, and after receiving the intelligent contract request, any node on the blockchain network may execute a corresponding task.
In this embodiment, after receiving the device information, each node in the block chain network performs data synchronization first, and then writes the device information into the block chain through the consensus protocol of each node, so that the security of the device information can be improved, and the device information is prevented from being tampered and forged.
