Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, as presented in the figures, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
In the prior art, in order to increase the security of data transmission, only data to be transmitted is encrypted, and the encrypted data is transmitted to a cloud storage server by using a fixed transmission link, however, when data transmission is performed by using the transmission method, the transmission link is unchanged, which easily causes the transmitted data to be acquired by hackers or enemies, especially, the data transmitted by troops or the data transmitted by public security authorities have high confidentiality, and once the data is leaked, a significant loss is caused.
Based on the above problem, as shown in fig. 1, an embodiment of the present application provides a method for data transmission, including:
s101, a sending end carries out fragment processing on a file to be transmitted to obtain at least two fragment files;
s102, the sending end determines a transmission strategy for each fragmented file according to the sending environment information;
s103, the sending end sends each fragment file to the receiving end according to the transmission strategy;
and S104, the sending end sends the transmission strategy to the receiving end.
In the step S101, the sending end may be a device that implements a data transceiving function, for example, a computer, a mobile phone, a tablet computer, and the like, which is not limited herein. The file to be transmitted may be data to be stored, such as a document, audio, video, picture, etc., and the application is not limited thereto. The fragment processing may be to cut the complete file by a preset cutting rule, where the preset cutting rule may be pre-stored in the sending end, and the preset cutting rule may be determined according to an actual situation, for example, the preset cutting rule may cut the complete file into n parts on average, or the preset cutting rule may cut the complete file according to a certain ratio (ratio is 1. When the file is fragmented, the complete file is obtained by cutting the complete file according to a preset rule, and if the complete file is cut into 3 parts according to the preset rule, a fragmented file 1, a fragmented file 2 and a fragmented file 3 are generated. In the application, data transmission is real-time transmission, and the condition of asynchronization does not exist between every two fragmented files.
Specifically, the leakage of transmission data can be caused by interception by a hacker or an enemy in the process of transmitting the complete file, the complete file to be transmitted can be cut into a plurality of fragments in order to improve the security of data transmission, even if the complete file to be transmitted is intercepted in the process of fragment transmission, the intercepted file is not the complete transmission file, and the leakage of the transmitted file is reduced because the intercepted file is incomplete. The file is fragmented, and a whole large file is divided into a plurality of small files, so that the transmission pressure of a transmission link can be reduced, and the data transmission efficiency is improved.
In the step S102, the integrated information may include one or more of the following information: and the sending end sends the sending environment information of the fragment files and the attribute information of the fragment files. The sending environment information may be information of an environment where the sending end sends the file to be transmitted, and the sending environment information may include any one or more of the following: the position of the sending end when sending the fragmented file and the time when the sending end sends the fragmented file. The transmission policy may be a transmission link selected by the transmitting end for each fragmented file according to the transmission environment information. A transmission link may be a path for a user to transmit data between a transmitting end and a receiving end. The transmission link may include a variety of forms, such as: the transmission link adopts a WiFi link, the transmission link adopts a mobile communication link, the transmission link adopts a satellite link and the like. The WiFi link needs to be provided with WiFi modules at the sending end and the receiving end, and the sending end and the receiving end are connected to the WiFi network through the WiFi modules, so that data interaction of the sending end and the receiving end is realized. The mobile communication link needs to install mobile communication modules at the sending end and the receiving end, the mobile communication modules can be 2G modules, 3G modules, 4G modules or 5G modules, and the like, and data interaction between the sending end and the receiving end is realized through a mobile communication technology. The satellite link needs to install satellite modules at the transmitting end and the receiving end, the satellite modules can achieve data interaction between the transmitting end and the receiving end through a satellite transmission technology, and the satellite transmission technology can achieve long-distance data transmission through an artificial satellite. Each form of transmission link may include at least one transmission link. The attribute information includes any one or more of the following: the quality condition of the fragmented files, the confidentiality condition of the fragmented files, and the classification condition of the fragmented files. The quality condition of the fragmented files can be the size of the fragmented files, the size of the fragmented files can be distinguished according to a preset numerical value, the quality of the fragmented files is high when the size of the fragmented files exceeds the preset numerical value, the quality of the fragmented files is low when the size of the fragmented files does not exceed the preset numerical value, the preset numerical value can be manually specified, and the fragmented files can be determined according to actual conditions. The secrecy of the fragmented files may be artificially defined, and the fragmented files may be divided into files with a high secrecy and files with a low secrecy. The fragment files may be classified according to the form of the fragment text, such as a voice file, a video file, a picture file, a text file, and the like, which is not limited herein.
Specifically, when the sending end sends the fragmented files, the sending end may select a corresponding transmission link according to the environment where the sending end is located. The sending end can select the corresponding transmission link according to the current position, or the sending end can select the corresponding transmission link according to the current time for sending the file to be transmitted.
The step S102 includes:
step 1021, aiming at each fragmented file, the sending end determines the transmission strategy for transmitting the fragmented file in the transmission link table according to the current sending environment information.
In step 1021, the sending environment information and the transmission link identifier in the transmission link table are stored in association with each other.
Specifically, after the sending end determines the sending environment information of the file to be sent currently, the transmission link corresponding to the sending environment information is found in the transmission link table, and then the transmission link of the fragmented file is determined.
For example, the current sending environment information is 10: 30, there are two fragment files, that is, fragment file 1 and fragment file 2, and the transmission link list is shown in table 1, then it is determined that the transmission link of fragment file 1 can be transmission link 4, and the transmission link of fragment file 2 can be transmission link 5, according to the current sending environment information.
TABLE 1
| Time information | Transmission link |
| 8:00-10:00 | 1、2、3 |
| 10:00-12:00 | 4、5、6 |
| 12:00-14:00 | 7、8、9 |
| 14:00-16:00 | 10、11、12 |
In order to make the determination of the transmission link of the fragmented file more accurate, the transmission link of the fragmented file may also be determined by a combination of different transmission environment information.
For example, the sending environment information of the fragmented files includes a time when the fragmented files are sent and a position where the fragmented files are sent, there are two fragmented files, which are a fragmented file 1 and a fragmented file 2, respectively, the sending end sends the fragmented file 1 at a location a, the sending time is 8: 30 minutes, the sending end sends the fragmented file 2 at a location B, the sending time is 13: 20 minutes, and the transmission link list is shown in table 2, it is determined that the transmission link of the fragmented file 1 may be a transmission link 2, and the transmission link of the fragmented file 2 may be a transmission link 7, according to the sending environment information of each fragmented file.
TABLE 2
In the above step S103, after determining the transmission link of each fragmented file in step S102, the sending end sends the fragmented file to the receiving end through the corresponding transmission link according to the determined transmission link.
In step S104, after the sending end sends the fragmented files to the receiving end, the receiving end does not know which fragmented files can form a complete file, and therefore, the sending end needs to send the transmission policy to the receiving end, so that the receiving end integrates the corresponding fragmented files according to the transmission policy to obtain the complete file.
In the embodiment of the application, through the four steps, after a complete transmission file is fragmented, the corresponding transmission link is selected for each fragmented file according to the comprehensive information, the fragmented files are transmitted to the receiving end through different transmission links, even if the fragmented files are intercepted, the complete transmission file cannot be obtained, and data leakage caused by the fact that data in the transmission process are intercepted is reduced.
Besides considering the sending environment information of the sending end to determine the transmission strategy for the fragmented files, the method can also consider the attribute information of the fragmented files, and the application also provides another data sending method, which comprises the following steps:
and 105, the transmitting end determines a transmission strategy for each fragment file according to the attribute information of each fragment file.
In the above step 105, the meaning of the attribute information may refer to the meaning of the attribute information mentioned above.
Specifically, step 105 includes:
step 1051, aiming at each fragmented file, the sending end determines a transmission strategy for transmitting the fragmented file in a transmission link list according to the attribute information of the fragmented file.
In the above step 1051, the attribute information of the fragment file in the transmission link list and the transmission link identifier are stored in association.
Specifically, in the transmission link list, the sending end selects one transmission link from the transmission links corresponding to the attribute information of the fragmented file.
For example, the attribute information of the fragmented files is the confidentiality of the fragmented files, two fragmented files are provided, namely, fragmented file 1 and fragmented file 2, the confidentiality of fragmented file 1 is high, the confidentiality of fragmented file 2 is low, and the transmission link list is shown in table 3, so that it is determined that the transmission link of fragmented file 1 can be transmission link 1, and the transmission link of fragmented file 2 can be transmission link 4, according to the confidentiality of each fragmented file.
TABLE 3
| Attribute information | Transmission link |
| High security | 1、2、3 |
| Low security | 4、5、6 |
In order to make the determination of the transmission link of the fragmented file more accurate, the transmission link of the fragmented file may also be determined by combining different attribute information.
For example, the attribute information of the fragmented file includes the confidentiality of the fragmented file and the quality of the fragmented file, there are two fragmented files, namely fragmented file 1 and fragmented file 2, the confidentiality of fragmented file 1 is high, the quality of fragmented file 1 is 1005KB, the confidentiality of fragmented file 2 is low, and the quality of fragmented file 2 is 300KB, and the transmission link list is shown in table 4, so that it is determined that the transmission link of fragmented file 1 can be transmission link 2, and the transmission link of fragmented file 2 can be transmission link 7, according to the confidentiality and the quality of each fragmented file.
TABLE 4
In addition to the determination of the transmission link through the combination of two attribute information and the determination of the transmission link through the combination of three attribute information given in the above example, the determination method may refer to the above step of determining the transmission link, and will not be described too much here.
In order to make the transmission of fragmented files more uncertain and to reduce the interception of fragmented files in the transmission link, a transmission policy may be determined for each fragmented file by sending a combination of environment information and attribute information of the fragmented file. The application provides another data transmission method, which comprises the following steps:
and 106, the sending end determines a transmission strategy for each fragmented file according to the sending environment information and the attribute information of each fragmented file.
In step 106, a corresponding transmission link is specifically determined for each fragmented file according to the sending status information and the attribute information corresponding to each fragmented file.
As shown in fig. 2, in step 106, an embodiment of the present application provides a method for determining a transmission policy, including:
s1061, the sending end screens out a transmission link list corresponding to the environment information from a transmission link library according to the sending environment information;
s1062, for each fragmented file, the sending end determines, according to the attribute information of the fragmented file, a transmission policy for transmitting the fragmented file in the transmission link list.
In the above step S1061, the transmission link library sends the environment information and the transmission link list for key storage, and the attribute information of the fragment file and the transmission link identifier in the transmission link list are stored in association.
Specifically, a transmission link list corresponding to the current sending environment information is found in a transmission link library according to the sending environment information of the current sending fragmented file of the sending end. By sending the combination of the environment information and the fragmented files, the transmission link can be timely changed, and the possibility of intercepting the fragmented files can be further reduced.
For example, when the sending environment information is the place a, a transmission link list for performing associated storage on the confidentiality of the fragmented file and the transmission link identifier can be determined in the transmission link library; when the sending environment information is the place B, a transmission link list for performing associated storage on the quality of the fragmented files and the transmission link identifiers can be determined in the transmission link library.
In the step S1062, after the transmission link list is determined in the step S1061, a transmission link of each fragmented file may be determined according to the attribute information of the fragmented file.
It will be appreciated from the above discussion that determining the transmission link for fragmented files may include any one or more of the following: and the sending end sends the sending environment information of the fragment file and the attribute information of the fragment file.
The transmission link can be randomly selected to transmit the fragmented files, so that the unit ensures that the receiving end can arrange the fragmented files into a complete file, and the transmitting end is required to transmit the randomly determined transmission strategy to the receiving end. The random determination of the transmission link can also reduce the possibility of intercepting the transmission file, and further reduce the possibility of leaking the data corresponding to the complete file.
In the prior art, there may also be a transit node having a connection relationship with a transmission link, and the intermediate node may include a base station, a server, a terminal device, a router, and the like, which is not limited herein. The transit node may be used to cache data. When a transmission link and a transit node are in a one-to-one correspondence relationship, the transit node does not need to be selected in the process of transmitting fragmented files. However, when one transmission link corresponds to a plurality of relay nodes, in order to more effectively improve the security of data transmission, the relay nodes may be determined for each fragmented file according to the integrated information, that is, the determination of the transmission policy includes determining the transmission link and determining the relay nodes.
In the process of transmitting fragmented files, when one transmission link corresponds to a plurality of transfer nodes, for one fragmented file, a transmission link corresponding to the fragmented file is determined according to the data transmission method, and then a transfer node is determined from the transfer nodes corresponding to the determined transmission link according to the current sending environment information and/or the attribute information of the fragmented file to transmit the fragmented file.
