Specific implementation mode
Technical scheme of the present invention is described in further detail below in conjunction with the accompanying drawings, the given examples are served only to explain the present invention,
It is not intended to limit the scope of the present invention.
Block chain technology is a kind of decentralization, does not depend on third party, carries out network data by itself distributed node
Storage, self-authentication, management, encrypted transmission a kind of technical solution.Block chain technology can make up mMTC applications well
Aforementioned drawback in scene.Block chain technology can be to provide point-to-point distributed data transport and storage under mMTC networks

The safety of transmission, this is particularly important.The present invention proposes a kind of 5G mMTC aggregation node modules based on block chain technology
Design method to ensure the safety of data transmission in mMTC, while improving single macro base station cell in mMTC application scenarios
System user connects quantity.
The application scenarios of 5G are broadly divided by China IMT-2020 propulsions group：Continuous wide area covering, hot spot high power capacity, low work(
The big connection of consumption, low time delay are highly reliable.Low-frequency resources in 5G are mainly used for that continuous wide covering, low time delay is highly reliable, low-power consumption is big
The application scenarios such as connection, and the main carriers of low-frequency resources are macro base station.It is main for the hot spot high power capacity scene for being deployed in high frequency
Microcellulor is applied, i.e., using micro-base station as base main body.It, can also be single macro for mMTC, the i.e. big connection scene of low-power consumption
The tip of cellular cell disposes three or more micro-base stations, is connected in enhanced room, further expands network capacity, mitigate macro base station
Connection burden.The single macro cells of mMTC scenes are as shown in Fig. 2, contain eight micro- bases in macro cells in the present embodiment
It stands, i.e. eight application scenarios.
According to described hierarchical network before in single macro base station cell in mMTC application scenarios, according to user terminal
Type of service and geographical location are grouped it, and user terminal, which is divided into different types of user, to be gathered, then apply it is non-just
Hand over multiple access（NOMA）Technology accesses micro-base station to user terminal.In a user terminal user gathers, convergence terminal user comes
Other machine type equipments in coordinates user set access network by double jump link, and convergence terminal may be tied in a distributed manner
Structure is present in single serving cell.Therefore in a user gathers, several convergence terminals user can be selected, and it is other
Terminal user then be used as general subscriber terminal.From allomeric function, only biography is encrypted to data in Generic End-User
It is defeated, and convergence terminal user then calculates and manages to the data of Generic End-User, merchandises to it as block chain
Its convergence terminal user is transmitted, while convergence terminal user does not preserve data, is only used as the terminal of data transmission, rises
The effect of data safety and secret protection is arrived.As shown in Figure 2 it is found that in the single macro base station cell of mMTC scenes, there are two
Kind of block chain structure, the first block chain structure being made of the convergence terminal user in each application scenarios are for second
The block chain structure being made of the Generic End-User in single application scenarios and the convergence terminal user in the scene.
Design about convergence terminal user constructs, and the present invention mainly proposes the Process Design for accessing network：User is whole
The monitoring of the authentication mechanism at end, the Data Encryption Transmission and user terminal of convergence terminal.
One, the authentication mechanism of terminal user.
Pass through the design of the user grouping set to the single macro cells of mMTC application scenarios, it is known that when ordinary terminal is used
Family and convergence terminal user will be linked by authentication in corresponding network before carrying out data transmission.Therefore to list
For a user's set, the authentication for completing convergence terminal user is first had to, it is made to be linked into block chain network；Secondly general
Logical terminal user carries out authentication verification by converging user terminal, it is made to be linked into single user's gathering network.
In block catenary system, the basis of ownership authentication mechanism is rivest, shamir, adelman.In rivest, shamir, adelman
In, there are two keys, i.e. public key and private key.If data are encrypted using public key, corresponding private key is only used
It can be decrypted；If data are encrypted with private key, only can be just decrypted using corresponding public key.Non- right
Claim in cryptographic communication system, each user contains a pair of of public key and private key, but only public key external disclosure, private key only user's sheet
Body is held.When being communicated, information source is encrypted using private key, and transmitted information once reaches the stay of two nights, stay of two nights use pair
The public key answered is decrypted, this ensures that data could be checked by only receiving both sides.It is asymmetric to add in block catenary system
There are two types of the basic usage scenarios of close algorithm：
A）Public key encrypts Transaction Information, and private key decrypts Transaction Information.After private key holder decryption, the friendship received can be used
Easy information.
B）Private key is to Information Signature, public key verifications signature.It can be confirmed by the information of public key signature verifications and held for private key
What someone was sent out.
Intelligent contract based on block chain encapsulates contract state, the contents such as trigger condition and contract operation.Signature is closed
User about reaches consistent with regard to treaty content, is deployed in the form of code on block chain, when external input affairs and event are full
When sufficient trigger condition, automatic activation intelligence contract simultaneously executes.By using asymmetric arithmetic and intelligence contract based on block chain
Complete subscriber terminal authority certification, specific details are as follows.
The authentication flow of convergence terminal user is as shown in figure 3, include step：
Step11：Convergence terminal user sends registration request, block chain to the block chain network being made of convergence terminal user
Return to convergence terminal user's a pair of public key and private key；Wherein address of the public key as convergence terminal user on the block chain,
Unique key of the private key as corresponding decryption；
Step12：Convergence terminal user reaches a intelligence about subscription authentication certification with all terminal users on the block chain
Energy contract, the terminal user of participation is signed with respective private key respectively, to ensure the validity of contract；
Step13：Intelligent contract diffuses to each convergence terminal user by way of P2P in the block chain network, and first protects
It is stored in terminal user's memory of each participation, waits for common recognition and processing of the common recognition time triggered to the intelligent contract of this part；
Step14：Come temporarily when the common recognition time, each convergence terminal user is all intelligent contracts preserved in nearest a period of time
It is packaged into a contract set, and the hash value of this contract set is calculated, then by the hash value of this contract set
It is assembled into a block structure and is diffused into the whole network；After other convergence terminal users receive this block structure, include the inside
The hash value of contract set extracts, and is compared with the contract set oneself preserved；Oneself a approval is sent simultaneously
Contract set give other convergence terminal users；By this transmissions taken turns and compare, all convergence terminal users are advising more
Reach an agreement to newest contract set in the fixed time.
This is arrived, then completes the authentication of convergence user terminal, it is made to be linked into block chain network.
Due to general subscriber terminal, i.e. smart machine node, the encrypted transmission of data is only carried out, therefore is directed to single use
Family set constructs small-sized block chain network, and in the network, convergence terminal is only deployed as verification node.There is ordinary user
Authentication it is as shown in Figure 4：
Step21：The Generic End-User block chain network that user terminal is constituted in by single application scenarios sends registration and asks
It asks, block chain returns to Generic End-User a pair of public key and private key；Wherein public key as Generic End-User in the block chain
On address, unique key of the private key as corresponding decryption；
Step22：Generic End-User reaches a intelligence about subscription authentication certification with all terminal users on the block chain
Energy contract, the terminal user of participation is signed with respective private key respectively, to ensure the validity of contract；
Step23：Intelligent contract diffuses to each convergence terminal user by way of P2P in the block chain network, and first protects
It is stored in terminal user's memory of each participation, waits for common recognition and processing of the common recognition time triggered to the intelligent contract of this part；
Step24：Come temporarily when the common recognition time, each convergence terminal user is all intelligent contracts preserved in nearest a period of time
It is packaged into a contract set, and the hash value of this contract set is calculated, then by the hash value of this contract set
It is assembled into a block structure and is diffused into the whole network；After other convergence terminal users receive this block structure, include the inside
The hash value of contract set extracts, and is compared with the contract set oneself preserved；Oneself a approval is sent simultaneously
Contract set give other convergence terminal users；By this transmissions taken turns and compare more；All convergence terminal users are advising
Reach an agreement to newest contract set in the fixed time.
Block chain Technology application can effectively be reduced into mirror in terminal user's authentication without third party device
Cost is weighed, safety is improved, prevents illegal terminal equipment from pretending, while terminal device can also be prevented by external attack.
Two, about the Data Encryption Transmission of convergence terminal.
After completion convergence terminal user and general subscriber terminal are linked into corresponding block chain network, eventually about convergence
The data transmission at end is as shown in Figure 5.Diagram as it can be seen that the data transmission about convergence user terminal there are mainly two types of scene；
Scene one：In the set of user terminals where converging user terminal itself, user terminal and general subscriber terminal are converged
Between data transmission.
Scene two：It converges user terminal and the information of other convergence terminal users is transmitted.
For above two data transmission scene, it can be based on block chain technology, data encryption is carried out using following below scheme

It asks, block chain returns to Generic End-User a pair of public key and private key；Wherein public key as Generic End-User in the block chain
On address, unique key of the private key as corresponding decryption；
Step22：Generic End-User reaches a intelligence about subscription authentication certification with all terminal users on the block chain
Energy contract, the terminal user of participation are signed with respective private key respectively；
Step23：Intelligent contract diffuses to each convergence terminal user by way of P2P in the block chain network, and first protects
It is stored in terminal user's memory of each participation, waits for common recognition and processing of the common recognition time triggered to the intelligent contract of this part；
Step24：Come temporarily when the common recognition time, each convergence terminal user is all intelligent contracts preserved in nearest a period of time
It is packaged into a contract set, and the hash value of this contract set is calculated, then by the hash value of this contract set
It is assembled into a block structure and is diffused into the whole network；After other convergence terminal users receive this block structure, include the inside
The hash value of contract set extracts, and is compared with the contract set oneself preserved；Oneself a approval is sent simultaneously
Contract set give other convergence terminal users；By this transmissions taken turns and compare more；All convergence terminal users are advising
Reach an agreement to newest contract set in the fixed time.
8. the 5G mMTC aggregation node module construction methods based on block chain according to claim 5, it is characterised in that convergence
The Data Encryption Transmission flow of terminal user includes step：
Step31：Transmitting side terminal user is encrypted data using the private key of itself, and into entire block chain network into
Row broadcast；
Step32：Receiving terminal terminal user is decrypted using corresponding public key to receiving data, and the data information to receiving
The legitimacy of transaction is tested, and by covering timestamp after inspection, data information is included into a block；
Step33：All convergence terminal users give the data information received transaction to cover timestamp in entire block chain network,
And it is included in block, while to onblock executing common recognition mechanism；
Step34：Block is stored by being formally included in block chain after algorithmic procedure of knowing together, and is owned in entire block chain network
Convergence terminal extended based on the block chain with the block, the manufacture of new block is received per family.
9. the 5G mMTC aggregation node module construction methods based on block chain according to claim 5, it is characterised in that terminal
The monitoring flow of user includes step：
Step41：Terminal user must first be registered as the user of the block chain, be carried out at the same time authentication；
Step42：It needs all terminal users being monitored to decide through consultation a intelligent contract monitored about user jointly, participates in
Terminal user signed respectively using respective private key；
Step43：Intelligent contract is broadcasted in the block chain network by way of P2P, is sent to each terminal user,
Intelligent contract after signature can be present among block chain network according to content therein in the form of code；In block chain
The intelligent contract received is first saved in memory by convergence terminal user, and common recognition time triggered is waited for be total to the intelligent contract of this part
Know and handles；
Step44：Come temporarily when the common recognition time, each convergence terminal user is all intelligent contracts preserved in nearest a period of time
It is packaged into a contract set, and the hash value of this contract set is calculated, then by the hash value of this contract set
It is assembled into a block structure, is diffused into the whole network；After other aggregation nodes receive this block structure, the conjunction that include the inside is understood
The hash value about gathered extracts, and is compared with the contract set oneself preserved；A conjunction oneself approved is sent simultaneously
About gather to other convergence terminal users；By this transmissions taken turns and compare more；All convergence terminal users are defined
Reach an agreement to newest contract set in time；Once the data information that terminal user sends simultaneously meets touching for intelligent contract
Clockwork spring part, block chain network are automatically processed according to intelligent contract.
