All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present specification without any creative effort shall fall within the protection scope of the present specification.
In order to better understand the inventive concept of the present application, a block diagram of a data transmission system based on a blockchain network in the embodiments of the present specification is first introduced. As shown in fig. 1, the data transmission system includes a wireless sensor, a base station node, and a block chain network. The block chain network also comprises an identity authentication node and a consensus accounting node.
The wireless sensor may be a device for acquiring a corresponding event within or near the sensed object. The wireless sensors form a wireless network in an ad hoc manner, so that specific information in a network coverage area can be perceived, collected and processed in a cooperative manner. In addition, the self-organizing network formed by the wireless sensors can be connected to the base station nodes in a multi-hop mode. The wireless sensor can also be used for acquiring identification information corresponding to each identity authentication node in the block chain network and generating a corresponding key according to the identification information and the monitored event data. The wireless sensor can also distribute corresponding random numbers for each identity authentication node, so that the corresponding digital signature can be calculated to verify the identity of the wireless sensor.
The base station node is a sink node in the wireless sensor network, is responsible for the connection between the sensor network and an external network, and can be used as a gateway node to realize the communication between the wireless sensor and the block chain network. In this embodiment, the base station node may receive data from a plurality of wireless sensors, and aggregate the data for transmission to the blockchain network. The base station node also has the authority to encrypt and authorize data, share information and the like, so that the data is received and sent.
The block chain network is responsible for providing network resources, computing resources and storage resources according to a networking resource request of a user, creating block chain networking services, selecting a block chain product mirror image according to a block chain product standard of the user, configuring virtual node resources and the like.

The consensus accounting node is a basic component in a blockchain network and is mainly responsible for blockchain transaction access and processing, intelligent contract execution, transaction formulas and transaction accounting are provided, and meanwhile, security services such as data encryption, decryption, identity authentication and the like are provided for transaction data.
Based on the data transmission system based on the blockchain network, a data transmission method based on the blockchain network in the embodiments of the present specification is introduced. The execution subject of the data transmission method based on the blockchain network can be the data transmission system based on the blockchain network. As shown in fig. 2, the data transmission method based on the blockchain network may include the following specific implementation steps.
S210: the wireless sensor collects the listening events.
The listening event may be an event that occurs within the detection range of the wireless sensor. The listening time may describe the activity of one or more objects within the detection range. Accordingly, the listening event may correspond to listening event data, and the listening event data may include at least one of event occurrence time, event occurrence location, event occurrence spatial location, and event description.
If the wireless sensor directly transmits the monitoring event data to the base station node after acquiring the monitoring event, data leakage or malicious data replacement is easily caused. A corresponding data signature may be generated in conjunction with the snoop event data to verify the identity of itself.
S220: the wireless sensor generates a symmetric key by using the monitored event data and the identity authentication node identification.
After the snoop event data is obtained, a symmetric key may be generated by using the snoop event data and the identity authentication node identifier. The identity authentication node identifier may be an identifier corresponding to each identity authentication node in the blockchain, and is used to uniquely determine the identity authentication node.
In some embodiments, the formula k-h (m, Gid) may be utilized 1 ,Gid 2 ,...,Gid r ) Calculating a symmetric key, wherein k is the symmetric key, h is a Hash function, m is monitoring event data, r is the number of identity authentication nodes, and Gid i And (1 < i < r) is identity authentication node identification.
S230: the wireless sensor selects a sending node and distributes node random numbers for other identity authentication nodes.
The sending node may be any one of the identity authentication nodes. In order to increase the difficulty of malicious behaviors made by lawless persons, the sending node may be a node randomly selected from the identity authentication nodes. The specific random selection mode may be set based on the requirements of the actual application, and is not described herein again.
In some embodiments, when selecting the sending node, an identity authentication node having a distance to the wireless sensor within a certain range may be selected as a candidate node based on the location of the wireless sensor, and then the sending node may be randomly selected from the candidate nodes. The embodiment reduces the data transmission distance, ensures the randomness of the selection of the sending node and improves the safety of data transmission.
S240: the wireless sensor calculates the sending node parameters by using preset network parameters, the node random number and the symmetric key.
After the node random number of each node is obtained, the sending node parameter can be calculated according to the node random number, the symmetric key and the preset network parameter. The preset network parameter may be a predetermined parameter before the data transmission procedure is performed. Specifically, a value v may be randomly selected as a preset network parameter, where v is an integer and is represented as a binary number: v ═ 0,1} b 。
The sending node parameter is a parameter corresponding to the selected sending node, and since a corresponding node random number is not allocated to the sending node, a formula corresponding to the sending node parameter can be constructed based on other node random numbers, a symmetric key and a preset network parameter, and a unique solution is obtained by solving the formula and is used as the sending node parameter. Because the sending node parameter is the only solution of the formula, after the sending node parameter is used for constructing the data signature, the base station node can construct a corresponding formula through the parameter contained in the data signature to verify whether the formula is established, so that whether the wireless sensor corresponding to the data signature is a normal sensor node is judged.
In some embodiments, when calculating the sending node parameter, the node random number may be first converted into the node calculation parameter by using a threshold function, and then the converted node calculation parameter is used to replace the node random number to achieve the calculation of the formula.
The threshold function has the function of limiting the number of bits of the binary number corresponding to the node random number within a certain range, so that the calculation is convenient to carry out. In particular, the formula y can be utilized i ＝g i (x i ) Calculating the node calculation parameter, wherein y i Calculating the parameter, x, for the node i Is a random number of the node, and is,
wherein f is a transfer function satisfying the bijective nature of the function,
means that the node is complemented with a random number with a number of bits less than b. It should be noted that the above formula is only used to describe the calculation process from the perspective of the function of the threshold function and the effect to be achieved, and is not used to refer to the actual formula in the actual operation process. The specific operation formula can be adjusted based on the above formula in combination with the application requirements, and is not described herein again.
Correspondingly, after the node calculation parameters are obtained, a formula C can be constructed by using the node calculation parameters k,v (y 1 ,y 2 ,...,y s ,...,y r ) And solving the formula, wherein,
is a symmetric key, v is a predetermined network parameter, y s To send the node parameter, y i (i ≠ s, i is more than or equal to 1 and less than or equal to r) is used as a node calculation parameter. E k Representing symmetric encryption with key k.
S250: the wireless sensor constructs a data signature by using preset network parameters, node random numbers, sending node parameters and identity authentication node identifiers.
After the sending node parameter is obtained through calculation, a data signature can be constructed by using a preset network parameter, a node random number sending node parameter and an identity authentication node identifier.
Based on the embodiment in S240, in the case where the node random number is converted into the node calculation parameter to obtain the transmission node parameter, the obtained transmission node parameter is in a format corresponding to the node calculation parameter and thus is not the same as the format of the node random number in the signature. For the above case, an inverse function of the threshold function may be obtained, and the sending node random number corresponding to the sending node may be restored using the inverse function. Correspondingly, the threshold function itself also satisfies the bijective property of the function, i.e. the independent variable and the function value are all in one-to-one correspondence. Specifically, the formula x can be utilized s ＝g s -1 (y s ) Completing the restoration of the random number of the sending node, wherein x s For transmitting node random number, g s -1 Is the inverse of the threshold function, y s Is the sending node parameter.
Accordingly, the constructed data signature may be s (m) ═ Gid (Gid) 1 ,Gid 2 ,...,Gid s ,...,Gid r ；v；x 1 ,x 2 ,...,x s ,...,x r ) In the formula, Gid i (i is more than or equal to 1 and less than or equal to r) is an identity authentication node identifier, v is a preset network parameter, and x i (1. ltoreq. i. ltoreq.r) are a node random number corresponding to each node and a transmission node random number.
S260: the wireless sensor sends the listening event data and the data signature to the base station node.
After building the data signature, the wireless sensor may send the listen event data and the data signature to the base station node.
In some embodiments, the wireless sensor may construct a network data message based on the data signature, the listening event data, the authentication node signature, the authentication node tagging parameter, the encryption security parameter, and the verification parameter, thereby transmitting the network data message to the base station node. The identity authentication node mark may be identification information different from the identity authentication node identifier corresponding to each identity authentication node, and the identity authentication node mark parameter may be a random number corresponding to the identity authentication node. These parameters may be parameters synchronized in the blockchain network, so that the security of the information can be determined by comparing the parameters. The encryption security parameter may be a unique identification parameter for the blockchain network, and also has an effect of ensuring the security of the data transmission process.
Specifically, the form of the network data packet may be represented as P M ＝(GID A1 ,...,GID Ar ,m,S,num,params A1 ,...,params Ar Param, chksum), wherein GID A1 ,...,GID An Representing identity authentication node marks, m is monitoring event data, S is a data signature, num represents the number of identity authentication main bodies, params i (1 ≦ i ≦ r) representing the identity authentication node tag parameter x i Params is the encryption security parameter and chksum is the verification parameter.
In some embodiments, the encryption security parameter may be a generated security parameter λ, and the initialization procedure GlobalSetup () is used to convert the security parameter into the encryption security parameter, i.e., GlobalSetup (λ) → Params.
S270: and the base station node generates a symmetric key according to the monitoring event data and the identity authentication node identifier.
After receiving the monitoring event data and the data signature, or receiving the network data message containing the above contents, the base station node may directly obtain the node random number, the sending node random number, the preset network parameter, and the identity authentication node identifier from the data signature.
And generating a symmetric key according to the monitoring event data and the identity authentication node identifier. The symmetric key is the same as the symmetric key obtained in step S220, and reference may be made to the description in step S220 for the description of the symmetric key. A specific way to obtain the symmetric key may be to use the formula k ═ h (m, Gid) 1 ,Gid 2 ,...,Gid r ) Calculating a symmetric key, wherein k is the symmetric key, h is a Hash function, m is monitoring event data, r is the number of identity authentication nodes, and Gid i And (1 < i < r) is identity authentication node identification.
In some embodiments, based on the embodiment in step S260, if the data sent by the wireless sensor to the base station node is a network data packet, and the network data packet includes a data signature, monitoring event data, an identity authentication node token, an identity authentication node marking parameter, an encryption security parameter, and a verification parameter, the data may also be verified in advance based on the network data packet.
Specifically, the check parameter chksum may be read from the network data packet first to verify the integrity of the data transmission. If the chksum parameter is normal, indicating that the data is not lost, and continuing to process the next step; if the inspection parameter is abnormal, the network data message is incomplete, and the processing flow is launched.
S280: and the base station node constructs a verification formula by using the symmetric key, the node random number and the sending node parameter and obtains a formula result.
The verification formula is a formula used in step S240 to calculate the sending node parameter, and when the calculated sending node parameter is the only solution, the result obtained by substituting each parameter into the verification formula should also match the formula result corresponding to the verification formula.
Specifically, the node random number may be first converted into a node calculation parameter, and then a formula y is used i ＝g i (x i ) Calculating the node calculation parameter, wherein y i Calculating the parameter, x, for the node i Is a random number for a node and is,
wherein f is a transfer function satisfying the bijective nature of the function,
means that the node is complemented with a random number so that the number of bits is less than b.
It should be noted that, even if the format of the obtained sending node parameter is the same as the format of the node random number, the format of the sending node parameter needs to be converted by using the threshold function; in the case where the format of the transmitting node parameter is different from the format of the node random number, the subsequent steps may be performed directly using the transmitting node parameter and the node calculation parameter.
Correspondingly, formula C is constructed based on the derived parameters k,v (y 1 ,y 2 ,...,y s ,...，y r ) In the formula
k is a symmetric key, v is a predetermined network parameter, y s To send the node parameter, y i (i is not equal to s and is not less than 1 and not more than r) is used as a node calculation parameter. And substituting the values of the parameters into the formula to obtain a formula result t.
Since the formula is consistent with the formula in step S240, if the data signature is provided by the correct wireless sensor, the data included in the data signature is also the real data, and the formula result obtained by calculation should correspond to the formula result in S240, i.e. the preset network parameters. If not, the data provided is wrong, and the subsequent processing request can be refused.
S290: and the base station node sends the monitoring event data to the block chain network under the condition that the formula result accords with the preset network parameters.
If the result of the formula conforms to the preset network parameters, it indicates that the node random number and the sending node parameters provided by the wireless sensor are determined according to the preset identifiers of the nodes, the preset network parameters, and the specific contents of the formula, that is, the wireless sensor is a normal sensor node, and the identity of the wireless sensor can be determined based on the received digital signature. In this case, the snoop event data may be sent into a blockchain network. Specifically, the consensus accounting node may execute an intelligent contract, synchronize the message PM to the whole network consensus accounting node, and then feed back a message delivery completion notification to the base station node, thereby completing registration of the monitoring event data in the blockchain network.
The specific signature verification process may be based on
If the output is true, the signature verification is successful, and if false is output, the signature verification fails.
In some embodiments, if the formula result does not meet the preset network parameters, the digital signature sent by the wireless sensor cannot verify the correctness of the identity of the wireless sensor, and may be disguised as data transmitted by the wireless sensor by a lawbreaker. In order to ensure the data security in the wireless sensor network and the block chain network, the transmission of the monitoring event data can be refused, and the wireless countermeasure network is prevented from being damaged.
The above method is further explained with a specific scenario example in conjunction with fig. 3. The wireless sensor 21 may be used to sense ambient event information. Wherein the wireless sensor A, B, C and the base station node 23 form a wireless sensing network. Accordingly, other wireless sensors and the base station node 23 may also form a corresponding wireless sensing network, for example, when the focus event 20 occurs, the wireless sensor a in the vicinity thereof may detect the event and transmit the event data to the base station node 23, such as the wireless sensor D, E, F and the VP 3. Specifically, the identifier of each authentication node 26 in the blockchain network 24 and the event data themselves may be used to generate a corresponding key during transmission, and generate a corresponding digital signature based on the manner in the above embodiment. The wireless sensor a may send the digital signature and the event data to the base station node 23, so that after the base station node 23 performs signature verification by using the digital signature, if the signature verification is successful, the event data is synchronized into the blockchain network 24, and the recording and transmission of the event data are completed by the consensus accounting node 25 in the blockchain network 24.
Assuming that a malicious eavesdropper 22 currently exists, when the eavesdropper 22 intercepts the data transmitted by one of the wireless sensors, the eavesdropper 22 cannot directly acquire specific event data because the event data and other data are mixed in the data transmitted by the wireless sensor. Even if the event data is acquired, if it cannot be determined which wireless sensor has transmitted the event data, the actual position corresponding to the event data cannot be located, and the event data cannot be used. Correspondingly, after the eavesdropper 22 sends the malicious data to the base station node 23, the base station node 23 checks the transmitted data, and under the condition that the eavesdropper 22 cannot acquire the corresponding information and the digital signature mode of the blockchain network 24, the eavesdropper 22 also fails to check the signature, so that the eavesdropper 22 is prevented from sending the malicious data to interfere with the blockchain network 24.
Based on the above description of the embodiment and the scenario example, it can be seen that, in the method, after the wireless sensor acquires the monitored event data, a symmetric key is generated by using the monitored event data and the identity of each node, and a sending node parameter of a sending node is obtained based on a random number corresponding to each node, so that a data signature is constructed by using the sending node parameter and other parameters. After the data signature and the monitoring event data are sent to the base station node, the base station node can acquire a corresponding parameter construction formula from the data signature based on the same logic, and judge whether the formula is established for signature verification, so that the identity of the wireless sensor is confirmed. By the method, the spatial position corresponding to the monitored event data is confused, the identity correctness of the wireless sensor is ensured, and the data transmission safety of the wireless sensor is ensured.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually manufacturing an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to the software compiler used in program development, but the original code before compiling is also written in a specific Programming Language, which is called Hardware Description Language (HDL), and the HDL is not only one kind but many kinds, such as abel (advanced boot Expression Language), ahdl (alternate Language Description Language), communication, CUPL (computer universal Programming Language), HDCal (Java Hardware Description Language), langa, Lola, mylar, HDL, PALASM, rhydl (runtime Description Language), vhjhdul (Hardware Description Language), and vhygl-Language, which are currently used commonly. It will also be apparent to those skilled in the art that hardware circuitry for implementing the logical method flows can be readily obtained by a mere need to program the method flows with some of the hardware description languages described above and into an integrated circuit.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
From the above description of the embodiments, it is clear to those skilled in the art that the present specification can be implemented by software plus the necessary first hardware platform. Based on such understanding, the technical solutions of the present specification may be essentially or partially implemented in the form of software products, which may be stored in a storage medium, such as ROM/RAM, magnetic disk, optical disk, etc., and include instructions for causing a computer device (which may be a personal computer, a server, or a network device, etc.) to execute the methods described in the embodiments or some parts of the embodiments of the present specification.
The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for the system embodiment, since it is substantially similar to the method embodiment, the description is simple, and for the relevant points, reference may be made to the partial description of the method embodiment.
The description is operational with numerous first or special purpose computing system environments or configurations. For example: personal computers, server computers, hand-held or portable devices, tablet-type devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments that include any of the above systems or devices, and the like.
This description may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The specification may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.
While the specification has been described with examples, those skilled in the art will appreciate that there are numerous variations and permutations of the specification that do not depart from the spirit of the specification, and it is intended that the appended claims include such variations and modifications that do not depart from the spirit of the specification.
