Based on the hardware framework of the intelligent home system, the first embodiment of the internet of things equipment management method based on the block chain system is provided.
Example one
The implementation provides an internet of things equipment management method based on a blockchain system, wherein the blockchain system at least comprises two main nodes which are in communication connection with each other, and each main node manages a plurality of node equipment which are in communication connection with the main node.
It should be noted that the master node may be set as a background server, and the background server may be used as a master node, and may store and monitor the device status of each node device, and may also send an instruction to each node device, and each node device completes a specific task based on the instruction, and moreover, information interaction between each node device also depends on the background server to perform data transmission. The node equipment can be intelligent household equipment, and an intelligent household system is formed by the plurality of intelligent household equipment and the background server. It is understood that the node device may also be an intelligent device in other fields, for example, when applied to the field of fire rescue, the node device may also be various sensors suitable for fire scene, such as a smoke sensor, a temperature sensor, etc. When the node equipment is applied to the field of logistics, the node equipment can also be a weight sensor, a bar code sensor and the like. In this embodiment, the host node is taken as a background server, and the node device is an intelligent home device. The intelligent household equipment comprises various intelligent household equipment which communicates with the background server through an Internet of Things (NB-IOT, which is called Narrow Band Internet of Things (NARROW) network, such as an intelligent curtain, an intelligent desk lamp, an intelligent projector, an intelligent sweeping robot and the like.
Referring to fig. 2, fig. 2 shows a system architecture of a block chain system, H (x) shows a background server, D (x, y) shows devices managed by H (x), a (x) shows an intelligent home system, x shows a number of the intelligent home system, y shows a number of the intelligent home device, and n shows a maximum number of the intelligent home devices in the intelligent home system.
Referring to fig. 3, the method for managing the internet of things device based on the blockchain system includes:
s110, any master node updates a first credit evaluation value and a second credit evaluation value, where the first credit evaluation value is obtained according to a degree or probability evaluation that the master node (i.e. a backend server) can provide effective services for other master nodes, and the second credit evaluation value is obtained according to a degree or probability evaluation that the node device can provide effective services for other node devices connected to the master node;
in order to improve the cooperation efficiency between the intelligent home devices in the intelligent home system, a trust mechanism needs to be established between the intelligent home devices, and the subjective abstract concept of trust is quantized through credit evaluation values, so that the intelligent home devices and the intelligent devices with higher credit evaluation values cooperate, namely data interaction and mutual communication are carried out, and further the cooperation efficiency between the intelligent devices is improved.
The first credit estimate is obtained according to a degree or probability estimate that the main node can provide effective services for other main nodes, specifically, the first credit estimate may be obtained according to a success rate of establishing a communication connection between the background server and other background servers, or according to a delay condition of establishing a communication connection between the background server and other background servers, and the first credit estimate may be quantized using a measurement range of 0 to 5. The following table illustrates the case where the first credit estimate is derived from the delay in establishing a communication connection between backend server H (1) and other backend servers.
The second credit estimate is derived based on an estimate of a degree or probability that the node device is capable of providing effective service to other node devices connected to the master node. Specifically, a second credit estimation value may be obtained according to a success rate of establishing a communication connection between the node device (i.e., the smart home device) and another smart home device, or according to a delay condition of establishing a communication connection between the node device (i.e., the smart home device) and another smart home device, where the second credit estimation value may be quantified using a measurement range of 0 to 5. Similarly, the following table illustrates a case where the second credit evaluation value is obtained according to a delay time of the smart home device D (1, 1) establishing a communication connection with another smart home device.
It should be noted that, the values of the first credit evaluation value and the second credit evaluation value are not fixed and unchanged, and the main node (i.e., the background server) updates the first credit evaluation value and the second credit evaluation value at intervals of a preset period, so that the node device (i.e., the smart home device) selects other node devices (i.e., other smart home devices) with higher credit evaluation values in real time for data communication, and the efficiency of cooperation is improved. In particular, the preset period may be set to 1-30 minutes, such as 10 minutes, 15 minutes or 20 minutes. Of course, the preset period can be flexibly set to other time lengths according to actual needs.
And S120, synchronizing the first credit evaluation value and the second credit evaluation value to each main node and node equipment in the block chain system based on a consensus algorithm.
In order to perform trust management among the participants across the smart home systems, the embodiment uses a block chain to implement the sharing and synchronization of trust data in the present invention. Blockchain technology is a distributed storage mechanism proposed that enables trusted data sharing and state consensus in a purely distributed environment. The block chain has the characteristics of distributed trust, non-tampering and public transparency. The distributed trust ensures the common recognition of uniqueness and correctness of the block chain copies among the intelligent home systems, the non-falsification ensures that data written into the block chain cannot be forged or modified maliciously, and the public transparency ensures that information on the block chain is open and all participants can check the information at any time.
Further, in this embodiment, a federation chain is used to implement sharing and maintenance of the first credit valuation and the second credit valuation in the distributed smart home system, and the advantages of using the federation chain mainly lie in that trust management and data sharing can be performed among different smart home systems without arbitration by a trusted third party.
In this embodiment, based on the byzantine fault-tolerant algorithm, when any one of the backend servers updates the first credit evaluation value and the second credit evaluation value, the backend server broadcasts the first credit evaluation value and the second credit evaluation value to all other backend servers and the smart home devices, and all other backend servers and the smart home devices keep the first credit evaluation value and the second credit evaluation value for accounting and storage, and the first credit evaluation value and the second credit evaluation value are not falsifiable. Therefore, sharing and synchronization of the first credit valuation and the second credit among the intelligent home systems and in the intelligent home systems are achieved. Through the block chain technology, the first credit evaluation value and the second credit evaluation value are stored in the main node and the node equipment and cannot be forged or modified maliciously, and the disclosure is transparent. The first credit estimate and the second credit estimate are made more accurate and reliable.
S130, the node equipment selects other node equipment to carry out data communication according to the first credit evaluation value and the second credit evaluation value.
After the first credit valuation and the second credit valuation are synchronized to each background server and each intelligent home device, the intelligent home devices with higher credit valuations are selected to directly carry out data communication based on the first credit valuations and the second credit valuations, for example, the intelligent home devices D (1, 1) of H (1) and the intelligent home devices D (2, 1) of H (2) with higher credit valuations are communicated to realize data interaction, and data interaction among the intelligent home devices of the cross-intelligent home system is realized; or the middle intelligent household equipment D (1, 1) of the H (1) is communicated with the intelligent household equipment D (1, 2) of the H (1) with higher credit evaluation value to realize data interaction, and the data interaction among the intelligent household equipment in the intelligent household system is realized.
In this embodiment, the trust degrees of the master nodes and the node devices in the blockchain system are quantized by setting the first credit evaluation value and the second credit evaluation value, and then the first credit evaluation value and the second credit evaluation value are synchronized to each master node and node device in the blockchain system based on a consensus algorithm, so that the node devices select other node devices with higher credit evaluation values according to the first credit evaluation value and the second credit evaluation value to perform data interaction. Therefore, the efficiency of data interaction between the intelligent home devices in the intelligent home system is improved.
The embodiment of the invention also provides a further optimized method for managing the equipment of the Internet of things based on the block chain system in the second embodiment, which is shown in the second embodiment.
Example two
Referring to fig. 4, the method for managing an internet of things device based on a blockchain system according to the embodiment includes:
s210, any main node updates a first credit evaluation value and a second credit evaluation value, wherein the first credit evaluation value is obtained according to the degree or probability evaluation value of effective service which can be provided by the main node for other main nodes, and the second credit evaluation value is obtained according to the degree or probability evaluation value of effective service which can be provided by the node equipment for other node equipment connected with the main node;
s220, any main node updates the first risk value and the second risk value; the first risk value is used for representing a risk value of the trust degree of the master node to any node device connected with the master node in a preset period, and the second risk value is used for representing a risk value of the trust degree of the node device to other node devices connected with the master node in the preset period;
the latest credit valuation of the intelligent home system and the intelligent home equipment in the intelligent home system provided by the block chain system can be inquired through the first credit valuation and the second credit valuation. For example, if there is a smart home device whose credit rating is always in continuous change of rising and falling, then although it may be higher at the time of the query, turning over its history of credit ratings over a period of time may create a doubt as to whether it has the current credit rating present. The concept of a risk value is set.
The first risk value is used for representing the risk value of the trust degree of the master node to any node device connected with the master node in a preset period. Specifically, the first risk value is set as the number of times that the evaluation value of the trust level of the master node to any node device connected to the master node is lower than a preset expected threshold value in a preset period, for example, the trust level of the background server to any smart home device to which the background server belongs is described by the success rate or the delay condition of the communication connection established between the background server and any smart home device to which the background server belongs, and then the trust level is quantified by using the measurement range of 0 to 5. The confidence level may be described with reference to the manner in which the first credit estimate is evaluated in the first implementation above. If the number of times that the trust degree is lower than the preset expected threshold value is too large in a preset period, the first risk value is considered to be high, and the trust degree of the intelligent household equipment is not stable enough. For example, if the confidence level is lower than the preset expected threshold for 10 times in a preset period, the first risk value is higher. The preset period and the preset expected threshold may be set according to actual needs, for example, the preset period is set to 1 to 7 days, specifically, the preset period is set to 3 days, and the preset expected threshold is set to 4. Within 3 days, if the number of times that the trust degree of the background server to any one of the smart home devices to which the background server belongs is lower than 4 exceeds 10 times, it is determined that the first risk value of the smart home device is high, and the trust degree of the smart home device for providing effective service is not stable enough. When the intelligent home devices are selected for data interaction, the first risk value is taken into consideration, so that the optimal intelligent home devices are searched for data interaction when the data interaction is carried out between the intelligent home systems, and the efficiency of the data interaction between the intelligent home devices in the intelligent home systems is improved.
The second risk value is used for representing a risk value of the trust degree of the node equipment to other node equipment connected with the main node in a preset period; in particular, the second risk value is set to the number of times the second credit estimate is below a preset desired threshold within a preset period. Similarly, if the second credit evaluation value is lower than the preset expected threshold for too many times in a preset period, the second risk value is considered to be higher, which indicates that the second credit evaluation value of the smart home device is not stable enough.
For example, the preset period is set to 1-7 days, specifically, the preset period is set to 3 days, and the preset expected threshold is set to 4. And in 3 days, if the number of times that the second credit valuation is lower than 4 exceeds 10 times, judging that the second risk value of the intelligent household equipment is higher, and enabling the second credit valuation of the intelligent household equipment for providing effective service to be not stable enough. When the intelligent home equipment is selected to perform data interaction, the second risk value is taken into consideration range, so that when data interaction is performed in the intelligent home system, the optimal intelligent home equipment is found to perform data interaction, and therefore the data interaction efficiency among the intelligent home equipment in the intelligent home system is improved.
S230, synchronizing the first credit evaluation value, the second credit evaluation value, the first risk value and the second risk value to each main node and node equipment in the block chain system based on a consensus algorithm;
based on the Byzantine fault-tolerant algorithm, when any one background server updates a first credit evaluation value, a second credit evaluation value, the first risk value and the second risk value, the background server broadcasts the first credit evaluation value, the second credit evaluation value, the first risk value and the second risk value to all other background servers and intelligent household equipment, and all other background servers and intelligent household equipment bill and store the first credit evaluation value, the second credit evaluation value, the first risk value and the second risk value, and the first credit evaluation value and the second risk value cannot be tampered. Therefore, sharing and synchronization of the first credit valuation and the second credit among the intelligent home systems and in the intelligent home systems are achieved.
And S240, the node equipment selects other node equipment for data communication according to the first credit evaluation value, the second credit evaluation value, the first risk value and the second risk value.
After the first credit evaluation value, the second credit evaluation value, the first risk value and the second risk value are synchronized to each background server and the smart home devices, the smart home devices with higher credit evaluation values are selected to directly perform data communication based on the first credit evaluation value, the second credit evaluation value, the first risk value and the second risk value. Compared with the first embodiment, in this embodiment, the smart home devices with higher credit valuations are selected to directly perform data communication based on the first credit valuation and the second credit valuation, and the first risk value and the second risk value are added as selection indexes.
