The data server may be located at the manufacturer or at the location of the user of the device. The content in the data server must be tamper-proof and the objects accessing the data server must have a legitimate identity and corresponding rights.
Referring to fig. 3, the method for coding the internet of things device based on the block chain includes the following steps:
s110, each Internet of things device sends a registration request to the registration server;
the internet of things equipment can be intelligent household equipment. It can be understood that the internet of things device can also be an intelligent device in other fields, for example, when the internet of things device is applied to the field of fire rescue, the internet of things device can also be various sensors suitable for fire scenes, such as a smoke sensor, a temperature sensor and the like. When being applied to the commodity circulation field, thing networking device can also be weight sensor, bar code inductor etc..
In this embodiment, each internet of things device may send a registration request to the registration server through a wireless communication manner such as 2G, 3G, 4G, 5G, bluetooth, or WI-FI.
S120, the registration server distributes an identification number to the Internet of things equipment according to a preset rule and forwards the identification number to an analysis server;
specifically, in this embodiment, two sets of preset rules are set for allocating identification numbers to the internet of things devices. In the first set of rules, the identification number includes a block chain number and a device number; more further, the blockchain number comprises 2 parts: [ Block number ] [ position number ]. The block number is determined by the block chain network and is used for indicating the block number of the block chain network where the identification number is located. The position number is used for representing the position of the identification number in the block. A serial number (given by the blockchain network) representing the block in which the identification code was registered on the blockchain network. The position number indicates the position (number from 0) within the block where the identification is encoded, i.e. which entry within the block. The device domain and the blockchain domain are separated by a "-" symbol. The manufacturer that obtains the blockchain domain code through the registration mode is called an internet of things identity owner.
The device number includes a standard code and a device code, and the device domain also includes 2 parts: [ Standard code ] # [ device code ]. The standard code is used for representing the type of the coding standard of the Internet of things, consists of various existing heterogeneous codes, does not adopt equipment with the existing coding standard, is treated according to the BCNS coding standard, and is uniformly distributed by the BCNS platform. The equipment code is used for representing the equipment number under the Internet of things coding standard corresponding to the standard code. The device code corresponds to an identification code of a certain device under a certain coding standard, and is uniformly coded by the coding standard mechanism to ensure uniqueness. For example, the identification code is: 123456.333-EPC-96 i #09.0134254.103423.2315472a2, it indicates that the 333 th entry of the id code in block 123456 is an id of a certain internet of things device using the EPC-96 i code standard.
Through the identification numbering mode, unique 'identifications' of the internet of things equipment with various heterogeneous internet of things coding standards can be stored in the block chain network.
In another set of identification rules, the identification number includes a block chain number, a feature number, and a device number. The difference between the identification rule and the previous expression rule is that the other set of identification rule also comprises a feature number, and the feature number adopts a serial number or a character string with a unique value. By additionally arranging the feature numbers, the distinguishing degree of the identification numbers is strengthened, and the uniqueness of the identification numbers is further improved.
S130, the analysis server forwards the registration request to a proper addressing server, and stores the identification number and the number of the addressing server.
Specifically, the analysis server selects an addressing server with abundant memory to forward the registration request according to the memory condition of the addressing server, and stores the identification number and the number of the addressing server. By numbering the identification number and the addressing server, subsequent query of the Internet of things equipment is facilitated.
S140, the addressing server searches for a data server corresponding to the Internet of things equipment and records the mapping relation between the data server and the identification number;
each physical network device has a data server matched with the physical network device, the data server stores data information of the Internet of things device and operation control information of the Internet of things device, and the information can be searched and used through a device identifier. And storing the mapping relation between the data server and the identification number, finding the unique data server matched with the physical network equipment through the identification number, and acquiring the data information of the physical network equipment and the operation control information of the Internet of things equipment from the data server.
S150, the addressing server feeds back registration success information to the Internet of things equipment, and the mapping relation between the data server and the identification number is stored in the block chain network.
Specifically, the registration success information includes the addressing server number and the identification number. By writing the identification number into the blockchain network and writing the digital abstract of the equipment data information into the blockchain network, entities accessing the equipment identification and the equipment data information must pass through a corresponding authentication mechanism of the blockchain network. The transactions between people, people and things and equipment can be restricted and flexibly customized through intelligent contracts in the blockchain nodes.
Further, the step of storing the mapping relationship between the data server and the identification number in the blockchain network includes:
s151, receiving a verification result of the mapping relation between the data server and the identification number by other Internet of things equipment through a block chain network;
specifically, after acquiring the mapping relationship record between the data server and the identification number, the other internet of things devices acquire all historical mapping relationships corresponding to the identification number according to the blockchain network, integrate the historical mapping relationships according to the timestamps of the historical mapping relationships, verify the validity of the mapping relationship between the data server and the identification number according to the integrated historical mapping relationships, and generate a verification result.
And judging the validity of the mapping relation between the data server and the identification number by other Internet of things equipment according to each timestamp and each state in the integrated historical mapping relation. Typically, the validity of the mapping relationship in the present application means whether the mapping relationship is the latest, and only all historical mapping relationships need to be checked when determining whether a mapping relationship is valid, and it is determined that the current mapping relationship is the latest record, that is, it is valid, according to the timestamps and states of all historical mapping relationships.
S152, the block chain network calculates the verification result by adopting a consensus algorithm to obtain a consensus result;
and S153, if the consensus result is that consensus is achieved, the verification is passed, the mapping relation between the data server and the identification number is recorded into the block chain network, and a corresponding consensus event is broadcasted.
The block chain network receives a verification result of the mapping relation (hereinafter referred to as mapping relation) between the data server and the identification number from other internet of things equipment, and calculates the verification result by adopting a consensus algorithm to obtain a consensus result. If the consensus result is that consensus is achieved, the verification is passed, the mapping relation is stored in a block chain, and a corresponding consensus event is broadcasted: if the consensus result is that the consensus can not be achieved, the verification is not passed, and the mapping relation is abandoned. When the data processing nodes of the block chain detect that a certain number of nodes pass the verification that the mapping relation passes the verification of the consensus algorithm, all other mapping relations can synchronously package the mapping relation into the block, so that most nodes carry out PBFT consensus verification on the mapping relation, the consistency of the mapping relation stored by all block chain nodes of the whole network is guaranteed, and all internet of things equipment synchronizes the mapping relation to all block chain nodes of the block chain network in real time or at regular time.
In this embodiment, the identification number of the internet of things device is obtained through allocation of the registration server, a suitable addressing server is found by the analysis server to forward the registration request, the mapping relationship between the data server and the identification number is recorded by the addressing server, and the mapping relationship between the data server and the identification number is stored in the blockchain network. And finally, through a consensus algorithm, an intelligent contract and an encryption signature algorithm technology of the block chain network, a trusted person or entity can obtain information or operation authority of the trusted Internet of things equipment, and through the block chain technology, an identification number matched with the Internet of things equipment is stored in the block chain network and cannot be faked or modified maliciously, so that privacy and safety protection of the Internet of things equipment are enhanced.
