The internet of things cloud platform is a core architecture of the internet of things and can be functionally divided into the following four platforms: a Connection Management Platform (CMP), a Device Management Platform (DMP), an Application Enablement Platform (AEP), and a Business Analysis Platform (BAP). The CMP is generally applied to an operator network, and an internet of things SIM card is connected to the CMP. The platform can realize connection configuration and fault management of the Internet of things, guarantee stability of a terminal networking channel, network resource usage management, connection tariff management, bill management, package change and the like. The DMP mainly comprises a series of functions of remote monitoring, setting adjustment, software upgrading, troubleshooting and the like of the terminal of the Internet of things, and helps a client to carry out system integration by providing an open API calling interface. The DMP may be mainly oriented to control of basic states of devices such as on, off, and stop, or real-time device warning of the internet of things, which does not relate to device management in an application scenario of the internet of things. The AEP is combined with an application scene, and provides functions of a complete set of application development tools (SDK), middleware, data storage, a business logic engine, a third party API interface and the like for developers. The BAP mainly comprises functions of big data service, machine learning and the like, and analyzes and processes data collected on the cloud platform and visualizes the data. Machine learning is the training of structured and unstructured data deposited on a platform to form predictive, cognitive, or complex business analysis logic.
In the embodiment of the application, the blockchain cloud platform provides one-stop, high-security, simple and easy-to-use blockchain service for enterprises and developers of the internet of things cloud platform by applying a blockchain technology on the internet of things cloud platform and utilizing the characteristics of peer-to-peer, open transparency, secure communication, difficulty in tampering, multi-party consensus and the like of blockchain main bodies. A cloud platform user does not need to acquire a block chain underlying technology, can quickly deploy a block chain network environment on the cloud, and is dedicated to block chain business mode innovation and business application development and operation. Most of the existing block chain cloud platforms are operated independently, a uniform industry standard is not formed, block chain services provided by a single block chain cloud platform are limited by resources of the cloud platform, and resource integration of cross-block chain cloud platforms needs to pay a great engineering transformation cost.
Based on this, the embodiment of the application provides a method and a system for accessing a block chain to an internet of things device, a convergence gateway and a storage medium. Referring to a system structure schematic diagram of an internet of things device access block chain shown in fig. 1, a convergence gateway includes an internet of things device access component and a plurality of block chain cloud platform access components, firstly, a plurality of service data sent by a plurality of internet of things devices are respectively encapsulated into different blocks through the internet of things device access component, and then the different blocks are respectively sent to different block chain cloud platforms through the plurality of block chain cloud platform access components, so that block chain service of a cross-block chain cloud platform can be realized, and resources of each block chain cloud platform do not need to be integrated.
Referring to fig. 2, a flowchart of a specific embodiment of a method for accessing a block chain by an internet of things device in the embodiment of the present application is shown. As shown in fig. 2, the method for accessing the block chain to the internet of things device in the embodiment of the present application includes the following specific steps:
s210, connecting the Internet of things equipment, and acquiring a plurality of service data sent by the Internet of things equipment;
and S220, respectively encapsulating the plurality of service data into blocks to obtain a plurality of blocks, and respectively sending the plurality of blocks to the corresponding block chain cloud platform.
The Internet of things equipment provided by the embodiment of the application is equipment which is connected with a sensing network layer and a transmission network layer in the Internet of things and used for acquiring data and sending the data to the network layer, such as an RFID card reader, an infrared sensor, an environmental sensor and the like. The internet of things equipment sends service data through various network interface modes (such as a GPRS module, an Ethernet interface, WIFI and the like). In some embodiments, the business data includes data collected by the internet of things device, configuration data of the internet of things device, or an intelligent contract. A Smart contract (Smart contract) is a computer protocol intended to propagate, verify or execute contracts in an informational manner. An intelligent contract is a set of digitally defined commitments that include protocols on which contract participants can enforce the commitments. The rights and obligations established by the intelligent contract are executed by a computer or a computer network.
A chunk is a data packet carrying transaction data in a blockchain network, and is a data structure that is tagged with a timestamp and a hash value of a previous chunk, and the chunk verifies and validates the transaction in the chunk through a consensus mechanism of the network. The hash value is usually represented by a short string of random letters and numbers, and is a "data fingerprint" obtained by a hash algorithm on input information of any length. In addition, the hash value is a unique and compact numerical representation form of a piece of data, and if the hash value is obtained by hashing a piece of plaintext, only any one letter in the piece of plaintext is changed, and the obtained hash value is different.
In some embodiments, encapsulating the service data into blocks specifically includes: and constructing an empty block, storing the service data into the block body, and storing the equipment identifier into the block head. The device identifier is used for distinguishing different Internet of things devices in the block chain network and serves as the unique identity identifier of the Internet of things devices in the block chain network. In some embodiments, the device identification includes a device identification code, a physical address of the device, or a factory serial number of the device, etc. And sending the block to a block chain cloud platform, thereby completing the chain transmission of the service data.
The plurality of service data are different service data, the first service data need to complete the uplink operation through the first block chain cloud platform, and the second service data need to complete the uplink operation through the second block chain cloud platform.
For example, the first block chain cloud platform provides a block chain service for storing and tracing data acquired by the internet of things equipment, and the second block chain platform provides a block chain service for storing and tracing configuration upgrade data of the internet of things equipment. The first service data is data collected by the Internet of things equipment, and the second service data is configuration upgrading data of the Internet of things equipment. The first service data can only complete the uplink operation through the first block chain cloud platform, but cannot complete the uplink operation through the second block chain platform. The second service data can only complete the uplink operation through the second blockchain platform, but cannot complete the uplink operation through the first blockchain cloud platform.
In some embodiments, before sending the block to the block chain cloud platform, the following specific steps are further included:
s221, sending a connection request to a block chain cloud platform, wherein the connection request comprises authentication information of the Internet of things equipment;
s222, obtaining a connection response of the block chain cloud platform, and connecting the block chain cloud platform according to the connection response.
In some embodiments, the access of the blockchain cloud platform needs to be authenticated, and the access can be connected to the blockchain cloud platform through the authentication of the blockchain cloud platform. By adopting the authentication mechanism, the risk that the block chain cloud platform is maliciously invaded and controlled can be reduced, and therefore the safety of the block chain cloud platform is improved.
Referring to fig. 3, a flowchart of another specific embodiment of a method for accessing a block chain by an internet of things device in the embodiment of the present application is shown. As shown in fig. 3, the method for accessing the block chain to the internet of things device in the embodiment of the present application includes the following specific steps:
s310, connecting the Internet of things equipment, and acquiring a plurality of service data sent by the Internet of things equipment;
s320, respectively carrying out digital signature on the plurality of service data to obtain a plurality of signature data;
s330, packaging the plurality of service data into blocks respectively to obtain a plurality of blocks, and sending the plurality of blocks to the corresponding block chain cloud platform respectively.
Digital signatures have two functions: one is to be able to determine that the message was indeed signed and sent by the sender because someone else cannot impersonate the sender's signature. Second, digital signatures can determine the integrity of a message. Because a digital signature is characterized in that it represents a characteristic of a document, if the document changes, the value of the digital digest will also change. Different files will get different digital summaries. The primary digital signature involves a hash function, the public key of the recipient, and the private key of the recipient.
The digital signature technique is to encrypt the digest information with the sender's private key and transmit it to the receiver together with the original text. The receiver decrypts the encrypted digest information using its own public key, and then generates a digest information for the received original text using a hash function, which is compared with the decrypted digest information. If the information is identical, the received information is complete and is not modified in the transmission process, otherwise, the information is modified, and therefore the digital signature can verify the integrity of the information.
In some embodiments, the service data is digitally signed, and the signature data and the service data are encapsulated into blocks, so that not only is the safety of uplink of the service data improved, but also the service data can be conveniently traced on the block chain.
Referring to fig. 4, a flowchart of another specific embodiment of a method for accessing a block chain by an internet of things device in the embodiment of the present application is shown. As shown in fig. 4, the method for accessing the block chain to the internet of things device in the embodiment of the present application includes the following specific steps:

s420, performing digital signature on the plurality of service data respectively to obtain a plurality of signature data;
s430, respectively verifying the plurality of signature data, and if the verification is passed, respectively packaging the plurality of service data and the plurality of corresponding signature data into blocks to obtain a plurality of blocks;
and S440, respectively sending the blocks to corresponding block chain cloud platforms.
And verifying the service data and the signature data, wherein the verification of the service data mainly comprises checking the legality of the service data, and the verification of the signature data mainly comprises verifying the identity of the equipment of the Internet of things and checking the integrity of the service data. If the verification of the service data and the verification of the signature data both pass, packaging the service data and the signature data into blocks; if the check on the service data is not passed, discarding the service data with errors; and if the service data passes the verification and the signature data does not pass the verification, discarding the error signature data, re-signing the service data to obtain new signature data, and re-verifying the new signature data.
In other embodiments, before step S420, the plurality of service data are respectively verified, and if the verification passes, the plurality of service data are respectively digitally signed to obtain a plurality of signature data.
Since the service data may have format problems or errors, for example, illegal data beyond the data range exists, or the data format does not conform to the uplink block protocol, preliminary verification of the service data is required to avoid waste of network resources of the block link.
Referring to fig. 5, a block diagram of a specific embodiment of a system for accessing a block chain by a device in the internet of things in the embodiment of the present application is shown.

In other embodiments, a plurality of block chain cloud platform access modules may be combined into one block chain cloud platform access module, and the one block chain cloud platform access module distinguishes a plurality of service data, and encapsulates the plurality of service data into different blocks respectively. In other embodiments, the internet of things device access module is connected to multiple internet of things devices, and different service data may be generated by one internet of things device or by multiple different internet of things devices.

The frequency of communication between the client and the service is reduced using an aggregation gateway that receives client requests, dispatches the requests to different backend systems, and then aggregates the results and returns them to the requesting client, thereby enabling a reduction in the number of requests issued by the application to the backend service and improving the performance of the application over a high latency network.
In some embodiments, the aggregation gateway accesses the internet of things devices with different services to the blockchain cloud platform corresponding to the services through relevant service configuration information, so as to provide blockchain services facing different internet of things operation services. If the service data is added or modified, the access configuration of the blockchain cloud platform of the internet of things equipment is changed in the service configuration information, and the relevant configuration information of the internet of things equipment does not need to be changed. In other embodiments, the aggregation gateway may further provide a corresponding operation interface (such as a web page or APP) to support a service configuration function, and face an internet of things service provider, so that the service provider may complete access configuration setting of a blockchain cloud platform of a service owned by the service provider through the operation interface.
The aggregation gateway encapsulates different service data into different blocks through different block chain cloud platform access components and respectively sends the different blocks to different block chain cloud platforms, so that block chain service of the cross-block chain cloud platform is realized, and the resources of each block chain cloud platform do not need to be integrated. In other embodiments, a plurality of block chain cloud platform access components may be combined into one block chain cloud platform access component, and the one block chain cloud platform access component distinguishes a plurality of different service data, and encapsulates the plurality of service data into different blocks respectively.
In other embodiments, the internet of things device access component is further configured to perform digital signature on the plurality of service data, respectively, to obtain a plurality of signature data. The service data are digitally signed through the Internet of things equipment access assembly, and then the signature data and the service data are packaged into blocks through the block chain cloud platform access assembly, so that the service data chaining safety is improved, and the service data can be conveniently traced on a block chain. In some embodiments, the internet of things device access component is further configured to verify the plurality of signature data. Before the blocks are packaged, the plurality of signature data are respectively verified through the Internet of things equipment access assembly, and invalid blocks are prevented from being generated, so that resource waste of a block chain cloud platform caused by the invalid blocks can be avoided, and performance waste caused by processing of the invalid blocks can be avoided. In other embodiments, the internet of things device access component is further configured to verify the plurality of service data and the plurality of corresponding signature data. The verification of the service data mainly comprises the step of checking the validity of the service data, and the verification of the signature data mainly comprises the steps of verifying the identity of the equipment of the Internet of things and checking the integrity of the service data. In other embodiments, the internet of things device access component verifies the plurality of service data before digitally signing the service data. Since the service data may have format problems or errors, for example, illegal data beyond the data range exists, or the data format does not conform to the uplink protocol of the block, preliminary verification needs to be performed on the service data, thereby avoiding waste of network resources of the block link.
