Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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 invention.
Example one
Fig. 1 is a flowchart of a method for processing data of an internet of things according to an embodiment of the present invention. The embodiment provides a method for processing data of an internet of things, which can be executed by a first internet of things device in an internet of things system and can be implemented in a software and/or hardware manner. As shown in fig. 1, the method for processing data of the internet of things provided by this embodiment includes:
Before this step is performed, the first internet of things device acquires the internet of things data, and then may perform preprocessing on the acquired internet of things data, for example: and packaging the data of the Internet of things, digitally signing the data and the like.
The data identification corresponds to the acquired data of the internet of things, and the data of the internet of things can be calculated by adopting a certain algorithm to obtain the data identification corresponding to the data of the internet of things one by one. For example: and carrying out hashing on the data of the Internet of things by adopting a hashing algorithm to obtain a characteristic character string with a fixed byte length as a data identifier.
102, the first internet of things device sends an authentication request message containing first internet of things device authentication information and a data identifier to each second internet of things device in the internet of things, so that each second internet of things device authenticates the first internet of things device authentication information according to a corresponding block chain, and the block chain contains authentication information of legal internet of things devices in the internet of things.
In this embodiment, the internet of things device that sends the authentication request message is referred to as a first internet of things device, the internet of things device that receives the authentication request message is referred to as a second internet of things device, and the number of the second internet of things devices may be at least three.
The first Internet of things equipment sends an authentication request message to each second Internet of things equipment, wherein the authentication request message comprises: the identity authentication information of the first Internet of things device and the data identification. And each second internet-of-things device receives the identity authentication request message, analyzes and extracts the content of the message, and authenticates the identity of the first internet-of-things device according to the extracted identity authentication information.
The specific content of the authentication information of the first internet-of-things device may include: one or more of physical address, equipment number, equipment identification and the like. Correspondingly, there are various ways to authenticate the first internet of things device.
In this embodiment, the authentication information of the first internet of things device may be a public key of the first internet of things device. In the process of establishing the Internet of things, a public key and a private key are distributed to each piece of Internet of things equipment according to a certain algorithm, wherein the private key is only stored by each piece of Internet of things equipment, and the public key can be issued to each piece of Internet of things equipment for storage. The algorithm for distributing the public key and the private key may employ an asymmetric encryption algorithm, for example: elliptic curve algorithms, public key encryption algorithms, etc.
And if the identity verification information of the first Internet of things equipment is the public key of the first Internet of things equipment, the second Internet of things equipment performs auditing according to the stored public keys of all the Internet of things equipment. In this embodiment, the public keys of all internet-of-things devices on the network (i.e., linked to the internet of things and legal) are written into the blockchain, which is equivalent to that all the internet-of-things devices corresponding to the public keys stored in the blockchain are legal. The blockchain may include: the system comprises an identity authentication block and a data verification block, wherein public keys of all on-line Internet of things devices are stored in the identity authentication block. Each piece of internet of things equipment corresponds to one block chain, and when the information of any piece of internet of things equipment is changed, broadcast messages are sent to all pieces of internet of things equipment on the internet, so that all pieces of internet of things equipment on the internet generate new blocks at the tail of the block chains, and the content of the block chains corresponding to all pieces of internet of things equipment on the internet is kept consistent.
The process of auditing the public key of the first internet of things device by the second internet of things device may specifically be:
and the second Internet of things equipment searches the public key of the first Internet of things equipment in the corresponding block chain, and if the public key is found, the first Internet of things equipment is legal Internet of things equipment on the Internet. And the second networking equipment which verifies the legal result sends an identity verification passing response message to all the networking equipment on the network to inform all the networking equipment, and the identity of the first networking equipment is proved to be legal through self verification.
The first internet of things device receives the identity verification passing response messages sent by the second internet of things devices, and in order to improve data security and accuracy, the first internet of things device can count the received identity verification passing response messages and calculate the ratio of the current count value to the total number of the second internet of things devices on the internet.
First thing networking device judges above-mentioned ratio, when the ratio exceeded preset proportion, also promptly: and when the ratio of the number of the received identity authentication passing response messages to the total number of the second networking equipment on the network exceeds a set ratio, the first networking equipment generates a new block containing the data identification in the corresponding block chain.
For example: assuming that the preset proportion is 50%, the number of the second internet-of-things devices on the network is 10, and when the number of the received identity authentication passing response messages is greater than 5, which is equivalent to the ratio greater than 50%, the first internet-of-things device can generate a new block and store the data identifier.
Specifically, the first internet of things device generates a new data check block in a corresponding block chain, and writes the data identifier into the new data check block. And the first internet of things device acquires the block number of the new block.
It should be noted that, due to the characteristics of the block chains, except that the first internet of things device generates a new block containing the data identifier in the corresponding block chain, the other second internet of things devices on the network also count the received authentication passing response messages sent by the other second internet of things devices, and generate a new block containing the data identifier in the corresponding block chain after the preset ratio is exceeded, so as to ensure that all block chains corresponding to the internet of things devices on the network are consistent. The source of the data identification is obtained from the authentication request message.
And 104, writing the data of the Internet of things, the data identification and the block number of the new block into a database by the first Internet of things device.
After the step 103 is completed, the first internet of things device writes the internet of things data, the data identifier and the block number of the new block into the database, and completes storage of the internet of things data.
When the data needs to be analyzed subsequently, the data of the Internet of things is read from the database. Then, the read internet of things data can be calculated according to the same algorithm as that in step 101, so as to obtain the data identifier of the data. And comparing the calculated data identification with the data identification stored in the database, and if the calculated data identification is the same as the data identification, indicating that the data stored in the database is not tampered.
In addition, the data identifier and the block number can be read from the database, the data identifier is searched in the data check block corresponding to the block number, and if the data identifier is found, the data of the internet of things is written by the legal internet of things equipment on the internet.
According to the technical scheme, the data identification corresponding to the internet of things data is obtained, the authentication request message containing the first internet of things equipment authentication information and the data identification is sent to each second piece of internet of things equipment in the internet of things, so that the first internet of things equipment authentication information is authenticated by each second piece of internet of things equipment according to the corresponding block chain containing all legal internet of things equipment authentication information, when the authentication passing response message exceeding the preset proportion is received, the new block containing the data identification is generated in the block chain corresponding to the first piece of internet of things equipment, then the internet of things data, the data identification and the block number of the new block are written into the database, and the storage of the internet of things data is completed. After passing the identity authentication of each second networking device, the Internet of things data can be stored, so that the source of the Internet of things data is ensured to be legal; and the data identification corresponding to the data of the Internet of things one to one is stored in the block chain, so that the data identification is ensured not to be falsified, the authenticity of the data storage of the Internet of things is ensured, and the storage process of the data of the Internet of things can be traced. The authenticity of the data of the internet of things can be verified when the data of the internet of things stored in the database needs to be analyzed subsequently, and if the data identification obtained by calculation according to the data of the internet of things stored in the database is different from the data identification stored in the database, the fact that the data of the internet of things is tampered can be found in time, and the phenomenon that the tampered data is directly analyzed to obtain an error result is avoided.
It can be understood that the identities of the internet of things devices in the internet of things can be mutually converted, and one internet of things device can be used as both a first internet of things device and a second internet of things device. Therefore, each piece of internet-of-things equipment can have the function of the first internet-of-things equipment and the function of the second internet-of-things equipment, and corresponding functions are executed in different roles.
Example two
In the embodiment, on the basis of the above embodiment, a processing method of internet of things data is further improved. The method can be executed by a first internet of things device in the internet of things system, and can be realized in a software and/or hardware mode.
In the technical solution provided in the first embodiment, the first internet of things device for acquiring the data of the internet of things is a legal device on the internet. If the internet of things data acquired by the illegal internet of things equipment which is not on the network needs to be stored in the database, a network access request needs to be carried out in advance, and the steps 102 to 104 in the first embodiment can be executed after the internet of things is linked and becomes legal internet of things equipment. In this embodiment, "on-net" does not refer to a structural wire connection, but refers to whether it is in an operating state with other internet-of-things devices.
Fig. 2 is a flowchart of a processing method of internet of things data according to a second embodiment of the present invention. As shown in fig. 2, before step 102, namely: before sending an authentication request message containing first internet-of-things device authentication information and a data identifier to each second internet-of-things device in the internet of things, the method further includes:
and 105, the first Internet of things equipment acquires the authentication information belonging to the first Internet of things equipment.
The specific content of the authentication information of the first internet-of-things device may include: one or more of physical address, equipment number, equipment identification and the like. In this embodiment, the authentication information of the first internet of things device may be a public key of the first internet of things device.
And 106, the first internet of things equipment sends a network access request message containing the authentication information to each second internet of things equipment in the internet of things, so that each second internet of things equipment writes the authentication information into the corresponding block chain.
The first Internet of things equipment sends a network access request message to each second Internet of things equipment in the Internet of things, wherein the network access request message contains a public key of the first Internet of things.
And each second networking device receives the networking request message, and analyzes and extracts the content of the message. Then, the second internet-of-things device may directly write the public key of the first internet-of-things device extracted from the message into the corresponding block chain, specifically, a new identity authentication block needs to be generated, and write the public key of the first internet-of-things device into the new identity authentication block.
Or, whether the first internet of things device agrees to network access can be determined according to the loading state of the internet of things. For example: the number of the internet of things devices currently linked into the internet of things can be judged, if the number exceeds a threshold value, the first internet of things device is not allowed to access the network, and the network access request message can be directly ignored or a network access refusal message can be sent to the first internet of things device.
And if the number of the Internet of things devices currently linked into the Internet of things does not exceed the threshold value, allowing the first Internet of things device to access the network. The second networking equipment sends the network access permission message to all the Internet of things equipment, and simultaneously receives the network access permission message sent by other second networking equipment. And the second networking equipment counts the number of the received allowed network access messages, and when the total number of the second networking equipment exceeds 51%, the second networking equipment writes the public key of the first networking equipment into the new identity authentication block, so that the first networking equipment is called as legal equipment.
It can be understood that, the first internet of things device also receives the network access permission messages sent by the second internet of things devices, and counts the number of the received network access permission messages, and when the total number of the second internet of things devices exceeds 51%, the first internet of things device also writes its own public key into the corresponding block chain, so as to ensure that the block chains corresponding to the internet of things devices on the network are consistent.
Thereafter, the first internet of things device may perform steps 102 to 104 in embodiment one.
According to the technical scheme, the data identification corresponding to the internet of things data is obtained, the authentication request message containing the first internet of things equipment authentication information and the data identification is sent to each second piece of internet of things equipment in the internet of things, so that the first internet of things equipment authentication information is authenticated by each second piece of internet of things equipment according to the corresponding block chain containing all legal internet of things equipment authentication information, when the authentication passing response message exceeding the preset proportion is received, the new block containing the data identification is generated in the block chain corresponding to the first piece of internet of things equipment, then the internet of things data, the data identification and the block number of the new block are written into the database, and the storage of the internet of things data is completed. After passing the identity authentication of each second networking device, the Internet of things data can be stored, so that the source of the Internet of things data is ensured to be legal; and the data identification corresponding to the data of the Internet of things one to one is stored in the block chain, so that the data identification is ensured not to be falsified, the authenticity of the data storage of the Internet of things is ensured, and the storage process of the data of the Internet of things can be traced. The authenticity of the data of the internet of things can be verified when the data of the internet of things stored in the database needs to be analyzed subsequently, and if the data identification obtained by calculation according to the data of the internet of things stored in the database is different from the data identification stored in the database, the fact that the data of the internet of things is tampered can be found in time, and the phenomenon that the tampered data is directly analyzed to obtain an error result is avoided.
In addition, the embodiment also describes in detail a way of storing data for an illegal first internet of things device that is not linked to the internet of things. The network access request message containing the identity verification information of the first Internet of things equipment is sent to the second Internet of things equipment on the network through the first Internet of things equipment, so that the identity verification information of the first Internet of things equipment is written into the corresponding block chains by the second Internet of things equipment, and the first Internet of things equipment becomes legal Internet of things equipment.
On the basis of the technical scheme, when a certain internet of things device needs to quit the internet of things, a network quitting request message needs to be sent to all other internet of things devices on the network. For example, when the first internet of things device needs to quit the network, the first internet of things device sends a network quitting request message to each second internet of things device, wherein the network quitting request message includes the authentication information, such as a public key, of the first internet of things device. And when the second internet-of-things equipment receives the network quitting request message, generating a new identity authentication block in the corresponding block chain, wherein the public key of the first internet-of-things equipment is deleted in the new identity authentication block. The first internet of things device also generates a new identity authentication block in the block chain corresponding to the first internet of things device, and the public key of the first internet of things device is deleted in the new identity authentication block.
EXAMPLE III
Fig. 3 is a flowchart of a method for processing data of the internet of things according to the third embodiment of the present invention. The embodiment provides a method for processing internet of things data, which can be executed by a second internet of things device in an internet of things system and can be implemented in a software and/or hardware manner. As shown in fig. 3, the method for processing data of the internet of things provided by this embodiment includes:
The identity verification information of the first internet of things device may specifically refer to the first embodiment, and the data identifier corresponding to the internet of things data collected by the first internet of things device may also refer to the first embodiment, which is not described herein again.
And the second networking equipment receives the authentication request message, and analyzes and extracts the content of the message.
The block chain corresponding to the second internet of things device stores all legal identity authentication information of the internet of things device, and can be used for authenticating the first internet of things device.
Specifically, if the authentication information is a public key, the process of verifying the public key of the first internet of things by the second internet of things device may specifically be:
the second internet of things equipment searches the public key of the first internet of things equipment in the corresponding block chain, if the public key is found, the verification is passed, and the first internet of things equipment is legal internet of things equipment on the internet; if the first internet of things device is not found, the verification is not passed, and the first internet of things device is illegal.
And the second networking equipment which verifies the legal result sends an identity verification passing response message to the first networking equipment so that the first networking equipment generates a new block containing the data identifier in the corresponding block chain, and writes the networking data, the data identifier and the block number of the new block into the database. The manner in which the first internet of things device generates the new block and writes each data into the database may refer to the above embodiments, and details are not repeated here.
In addition, the second networked device which verifies the legal result generates a new block containing the data identification in the block chain corresponding to the second networked device.
The second networking equipment which verifies the legal result also sends an identity verification passing response message to other second networking equipment on the network to inform all the Internet of things equipment, the identity of the first Internet of things equipment is shown to be legal through self verification, and all the second networking equipment generate new blocks containing data identifications in the block chains corresponding to the second networking equipment so as to ensure that the contents of the block chains corresponding to all the Internet of things equipment are kept consistent.
