Detailed Description
Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations such as "comprises" or "comprising", etc., will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
The technical scheme provided by the embodiment of the invention can be applied to a power distribution communication system based on the Internet of things, the power distribution communication system adopts a 5G communication technology, and the power distribution communication system needs to encrypt transmitted data. Therefore, in the following embodiments, the power distribution communication system based on the internet of things is referred to as a power distribution 5G communication encryption system based on the internet of things.
It can be understood that in the power distribution 5G communication encryption system based on the Internet of things, two major mainstream technologies, namely the Internet of things technology and the 5G communication technology, are utilized. The internet of things technology is embodied in cascade connection and deployment among devices, and the 5G communication technology is embodied in communication among the devices.
Therefore, referring to fig. 1, a schematic structural diagram of an internet-of-things-based power distribution 5G communication encryption system 10 provided in an embodiment of the present invention is shown, where the encryption system includes: a distribution main station 11 and a distribution terminal 12.
In some embodiments, the number of the power distribution terminals 12 may be multiple, each power distribution terminal 12 is deployed with the corresponding power distribution master station 11 through the internet of things, and when data transmission is performed, data transmission is performed based on a 5G communication technology.
In some embodiments, the number of power distribution master stations 11 may be one, corresponding to the number of power distribution terminals 12 that govern their responsibility. In other embodiments, the number of the power distribution main stations 11 may be multiple, and each power distribution main station 11 governs the plurality of power distribution terminals 12 in charge of the power distribution main station.
The distribution terminals 12 may or may not be connected to each other, and may be configured according to a specific application scenario, which is not limited herein.
For 5G communication technology and internet of things technology, reference may be made to technologies mature in the field, and an emphasis of the embodiment of the present invention is on encryption technology, and therefore, these two technologies are not described in detail herein.
For the sake of understanding, in the embodiment of the present invention, the encrypted communication technology is described in terms of the power distribution master station 11, the encrypted communication technology is described in terms of the power distribution terminal 12, and finally, the encrypted communication technology is described in combination with the two.
Referring to fig. 2, a flowchart of an encryption method for power distribution 5G communication based on the internet of things according to an embodiment of the present invention is shown, where the encryption method is applied to the power distribution master station 11, and the encryption method includes:
step 210: and acquiring the data to be transmitted and the transmission conditions corresponding to the data to be transmitted.
The data to be transmitted may be various types of data required in the power distribution network, and is not limited herein.
The transmission conditions are used to characterize the 5G communication environment of the power distribution terminal 12 that receives the data to be transmitted. In some embodiments, the power distribution master station 11 stores transmission condition information of each power distribution terminal 12 that it is responsible for administration, and the transmission condition information is continuously updated.
In some embodiments, the transmission conditions may include: the distance between the power distribution terminal 12 and the power distribution master station 11, the number of 5G base stations on the transmission path between the power distribution terminal 12 and the power distribution master station 11, and the number of interference sources on the transmission path.
Wherein the distance may be a straight distance between the power distribution terminal 12 and the power distribution main station 11. The number of 5G base stations can be understood as the number of deployed 5G base stations at the straight-line distance; and, the interference source can be understood as an object having influence on the signal transceiving of the 5G base station, such as: some objects which can emit fixed frequency bands, and some buildings which have shielding effect on signals, such as tunnels and the like.
It will be appreciated that different transmission conditions will have different effects on the data transmission between the distribution main station 11 and the distribution terminals 12, such as: when the transmission conditions are poor, the transmitted data is easily stolen or easily lost. Therefore, different encryption modes can be adopted based on different transmission conditions to ensure the safe and stable transmission of data.
Therefore, based on the transmission conditions, step 220 is performed: a plurality of encryption levels are determined according to transmission conditions.
For the encryption level, there may be different configurations in different application scenarios. In some embodiments, more levels of encryption may be configured, such as: 1-10, and sequentially improving the encryption level. In other embodiments, fewer levels of encryption may be configured, such as: and A-D, sequentially improving the encryption level.
As an alternative embodiment, step 220 includes: determining a first influence value according to the number of the 5G base stations, a preset first weight value, the number of interference sources and a preset second weight value; determining a second influence value according to the distance, the first influence value and a preset correlation coefficient; determining a plurality of encryption levels corresponding to the second influence value according to the second influence value and the encryption levels corresponding to the preset different influence value ranges; wherein each range of influence values corresponds to at least 2 encryption levels.
Wherein the first impact value may be expressed as: s1= M × A1+ N × A2, M is the number of 5G base stations, A1 is a first weight value, N is the number of interference sources, and A2 is a second weight value; and, A1+ A2=1.
In this way, the first weight value and the second weight value can be reasonably configured according to the influence of the number of 5G base stations and the number of interference sources on data transmission, so that the determined first influence value is more accurate.
The second impact value may be expressed as: s2= S1+ (S1 + D) × A3, D represents a distance, A3 represents a preset correlation coefficient, and A3 is smaller than 1, the correlation coefficient being used for characterizing the correlation between the distance and the number of base stations and the number of interference sources.
In this way, the magnitude of the correlation coefficient can be reasonably configured according to the further influence of the distance on the number of the base stations and the influence brought by the interference source, so that the determined second influence value is more accurate.
In the embodiment of the invention, the encryption levels corresponding to different influence value ranges are preset, and each influence value range corresponds to at least 2 encryption levels.
For example: assuming that the number of influence values is 0-100 and the encryption levels are 10 in total, 5 influence value ranges with an interval of 20 may be set correspondingly, each influence value range corresponding to 2 encryption levels.
The setting mode can avoid the jump of encryption level caused by the change of the influence value.
Furthermore, on the premise that the second influence value is known, the influence value range corresponding to the second influence value is found, and then the encryption level corresponding to the corresponding influence value range is determined as a plurality of encryption levels.
Step 230: an encryption confirmation command is generated based on the plurality of encryption levels and transmitted to the distribution terminal 12.
Wherein, at least two encryption levels corresponding to each influence value can be configured with different influence values, such as: one encryption level corresponds to an impact value of 0-4 of 0-10 and the other encryption level corresponds to an impact value of 5-10 of 0-10.
In such an embodiment, step 230 may include: determining recommendation scores corresponding to the encryption levels respectively according to the difference values between the influence values corresponding to the encryption levels respectively and the second influence values; and generating an encryption confirmation instruction according to the plurality of encryption levels and the recommendation scores respectively corresponding to the plurality of encryption levels.
In this embodiment, since there are a plurality of encryption levels, in order to make it possible for the power distribution terminal 12 to better select a target encryption level, a recommendation score may be set for each encryption level, and the power distribution terminal 12 may select a target encryption level according to the recommendation score.
For the power distribution terminal 12, after receiving the plurality of encryption levels sent by the power distribution master station 11, according to the selection rule of the corresponding target encryption level, the target encryption level is selected, and an encryption confirmation result is generated and fed back to the power distribution master station 11. The specific selection manner of the power distribution terminal 12 is described in the following embodiments.
Step 240: and receiving the encrypted confirmation result returned by the power distribution terminal 12. The encryption confirmation result includes a target encryption level.
Step 250: and determining the encryption algorithm of the data to be transmitted according to the target encryption level and the preset 5G encryption algorithm corresponding to different encryption levels.
In the embodiment of the invention, 5G encryption algorithms corresponding to different encryption levels are preset, and after the target encryption level is determined, the 5G encryption algorithm corresponding to the target encryption level is determined as the encryption algorithm of the data to be transmitted.
Step 260: and encrypting the data to be transmitted according to an encryption algorithm, and transmitting the encrypted data to the power distribution terminal 12 through the 5G network.
After the encryption algorithm is determined, the data to be transmitted may be encrypted using the encryption algorithm, and the encrypted data may be transmitted to the power distribution terminal 12 via the 5G network.
In some embodiments, prior to step 260, the encryption method may further comprise: encrypting the test data according to an encryption algorithm, and transmitting the encrypted test data to the power distribution terminal 12 through a 5G network; receiving a test data transmission result fed back by the power distribution terminal 12; and determining whether the encryption algorithm is a feasible encryption algorithm according to the test data transmission result. Correspondingly, when the encryption algorithm is determined to be a feasible encryption algorithm, step 260 is performed.
In this embodiment, the test data may be encrypted by using an encryption algorithm, the encrypted test data is then sent to the power distribution terminal 12, the power distribution terminal 12 feeds back a transmission result of the test data, if the transmission result represents that the encryption is successful, the encryption algorithm is feasible, and if the transmission result represents that the encryption is unsuccessful, the encryption algorithm is infeasible. If the encryption algorithm is feasible, step 260 may be performed to encrypt the data that is actually needed to be transmitted by using the encryption algorithm. And if the encryption algorithm is not feasible, the encryption algorithm needs to be determined again.
How the power distribution terminal 12 feeds back the transmission result of the test data is described in the following embodiments. And the test data can be data irrelevant to the data of the power distribution network, or other data which cannot influence the power distribution network, and the like.
For the power distribution main station 11, timely maintenance can be performed on the configured 5G encryption algorithm to ensure the stability and the security of the 5G encryption algorithm.
Therefore, as an optional implementation manner, the encryption method further includes: determining the use times corresponding to the 5G encryption algorithm corresponding to the preset different encryption levels; and updating the 5G encryption algorithm corresponding to each encryption level according to the using times.
In such an embodiment, the encryption algorithm is updated based on the number of uses. It can be understood that the more times the encryption algorithm is used, the worse the security and stability, and the less times the encryption algorithm is used, the better the security and stability.
In some embodiments, updating the 5G encryption algorithm corresponding to each encryption level according to the number of times of use includes: deleting the 5G encryption algorithm with the use times larger than the preset use times and the corresponding encryption grade; adjusting a 5G encryption algorithm with the use times smaller than the preset use times; the corresponding encryption levels are replaced aiming at the 5G encryption algorithm with the same use times; aiming at a plurality of 5G encryption algorithms of which the difference value between the using times is greater than a preset difference value, integrating the corresponding encryption levels, and resetting the integrated encryption level to the encryption levels corresponding to the plurality of 5G encryption algorithms; and updating the plurality of 5G encryption algorithms aiming at the plurality of 5G encryption algorithms with the difference value between the use times smaller than the preset difference value.
The preset number of times of use may be the maximum number of times of use allowed by the encryption algorithm, and after the number of times of use is exceeded, the encryption algorithm is equivalent to invalid. For example: the preset number of uses may be 5.
For the 5G algorithm with the use times smaller than the preset use times, the algorithm can be correspondingly adjusted and can still be used continuously.
By determining the difference of the number of times of use between any two 5G encryption algorithms, if the difference is 0, that is, the number of times of use is the same, the corresponding encryption levels can be directly replaced. If the difference is greater than the predetermined difference, for example: 5, integrating the encryption levels, for example: and performing weighted average on the two encryption levels, or taking the higher encryption level of the two encryption levels, and determining the integrated encryption level as the corresponding encryption level.
If the difference is smaller than the preset difference, the algorithm is directly updated, for example: increase the complexity of the algorithm, replace with other new algorithms, etc.
By the method, the encryption algorithm can be effectively updated, and the security and the stability of the encryption algorithm are ensured.
Referring to fig. 3, a flowchart of an internet-of-things-based power distribution 5G communication encryption method according to another embodiment of the present invention is shown, where the encryption method is applied to a power distribution terminal 12, and includes:
step 310: and receiving an encrypted confirmation command sent by the power distribution main station 11.
In conjunction with the description of the foregoing embodiment, the encryption confirmation command includes a plurality of encryption levels.
Step 320: and judging whether the 5G encryption algorithm corresponding to each encryption level is the locally stored 5G encryption algorithm.
In this step, the 5G encryption algorithms corresponding to the plurality of encryption levels are compared with the locally stored 5G encryption algorithm, and if the same encryption algorithm exists, the locally stored encryption algorithm is determined. If the same encryption algorithm does not exist, the encryption algorithm is not locally stored.
Step 330: and if the 5G encryption algorithm corresponding to each of the plurality of encryption levels is the locally stored 5G encryption algorithm, determining the encryption level corresponding to the locally stored 5G encryption algorithm with the least use frequency as the target encryption level.
In this embodiment, the encryption level corresponding to the 5G encryption algorithm that is used the least number of times is determined as the target encryption level, so as to ensure the indestructibility of the corresponding 5G encryption algorithm.
In other embodiments, with reference to the descriptions in the foregoing embodiments, if each encryption level corresponds to a recommendation score, the encryption level with the highest recommendation score is selected as the target encryption level. Or, the encryption level with a small number of uses and a high recommendation score is determined as the target encryption level. Or other determination means, and is not limited herein.
Step 340: and generating an encryption confirmation result according to the target encryption level, and transmitting the encryption confirmation result to the power distribution main station 11.
After the target encryption level is determined, an encryption confirmation result is generated and transmitted to the distribution master 11.
In some embodiments, the encryption method further comprises: if the 5G encryption algorithm corresponding to each of the plurality of encryption levels is not the locally stored 5G encryption algorithm, determining the average encryption complexity corresponding to the locally stored 5G encryption algorithm; determining a target encryption level according to the average encryption complexity and preset encryption levels corresponding to different encryption complexities; and generating an encryption confirmation result according to the target encryption level, and transmitting the encryption confirmation result to the power distribution main station 11.
In this embodiment, if the 5G encryption algorithm corresponding to each of the plurality of encryption levels is not the locally stored 5G encryption algorithm, the average encryption complexity corresponding to the locally stored 5G encryption algorithm may be determined, and then the encryption level corresponding to the average complexity may be determined as the target encryption level.
The complexity of the 5G encryption algorithm may be used as attached information, that is, when the 5G encryption algorithm is configured, the complexity information is configured.
As described in the foregoing embodiment, it is possible for the power distribution master station 11 to transmit the test data to the power distribution terminal 12 first. Accordingly, correspondingly, for the distribution terminal 12, the encryption method further includes: receiving encrypted test data sent by the power distribution master station 11; decrypting the encrypted test data; comparing the decrypted test data with locally stored test data; if the decrypted test data is consistent with the locally stored test data, determining that the transmission result of the test data is successfully encrypted; if the decrypted test data is inconsistent with the locally stored test data, determining that the test transmission result is encryption failure; and feeding back the transmission result of the test data to the power distribution main station 11.
In this embodiment, the test data is decrypted, and the consistency with the locally stored test data is determined, and by determining the consistency, it is determined whether the encryption was successful.
