Detailed Description
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 of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a first flowchart of a data transmission method according to an embodiment of the present application.
The data transmission method provided by the embodiment of the application can comprise the following steps:
step S101: the sending terminal acquires target data.
In practical application, the target data acquired by the sending terminal may be determined according to actual needs, for example, the data to be transmitted selected by the user in the sending terminal may be used as the target data. The type of the target data can also be determined according to actual needs, for example, the target data can be video, audio, pictures, and the like.
Step S102: and if the target data needs to be transmitted out of the sending terminal, the sending terminal automatically encrypts the target data to obtain encrypted data.
In practical application, when the target data needs to be transmitted out of the transmitting terminal, the transmitting terminal can automatically encrypt the target data to obtain encrypted data, so that the data transmitted out of the transmitting terminal are all encrypted data, the target data are difficult to obtain by the outside, and the safety of the target data is protected; it is understood that when the target data is lost or leaked secret, the target data is required to be transmitted out of the sending terminal, and the sending terminal still encrypts the target data at the moment, so that the lost or leaked secret is only encrypted data but not the target data, and the leakage or loss of the target data is avoided.
It should be noted that the manner in which the sending terminal encrypts the target data may be determined according to actual needs, and is not described herein again; in addition, in a specific application scenario, in order to facilitate management of a data transmission process by the outside, an option whether to enable automatic encryption may be set in the sending terminal, so that the outside can control whether to encrypt target data or not when the sending terminal needs to transmit data out of the sending terminal itself through the option.
Step S103: the transmitting terminal transmits the encrypted data to the receiving terminal.
Step S104: if the encrypted data needs to be transmitted into the receiving terminal, the receiving terminal acquires a first security level of a transmitting terminal that transmits the encrypted data.
Step S105: and the receiving terminal automatically processes the encrypted data based on the first security level and the second security level of the receiving terminal to obtain processed data.
Step S106: the receiving terminal transmits the processed data into itself.
In practical application, the sending terminal transmits the encrypted data to the receiving terminal, and when the receiving terminal needs to transmit the encrypted data into itself, the first security level of the sending terminal can be obtained, and the encrypted data is automatically processed based on the first security level and the second security level of itself, and the processed data is transmitted into itself. It should be noted that, the sending terminal automatically encrypts data when transmitting data, and the receiving terminal automatically processes data when transmitting data, so that the sending terminal and the receiving terminal can automatically complete data protection without affecting user experience.
In a specific application scenario, when encrypted data is transmitted by a sending terminal, the first security level of the sending terminal can be transmitted to a receiving terminal together, so that the receiving terminal can directly obtain the first security level; in addition, the first security level of the sending terminal may also be set in the receiving terminal in advance, so that the receiving terminal may directly search for the first security level of the sending terminal and the like in itself.
It should be noted that the types of the sending terminal and the receiving terminal may be determined according to actual needs, for example, the sending terminal and the receiving terminal may be cloud terminals, tablets, mobile phones, notebook computers, PC hosts, and the like.
The data transmission method is applied to a sending terminal and used for obtaining target data; if the target data needs to be transmitted out of the sending terminal, the target data is automatically encrypted to obtain encrypted data; the encrypted data is transmitted to the receiving terminal. According to the data transmission method, when the target data needs to be transmitted out of the transmitting terminal, the transmitting terminal automatically encrypts the target data and transmits the encrypted data to the receiving terminal, so that the data transmitted by the transmitting terminal are all encrypted data, the external cannot acquire the original target data, and the safety of the target data is protected; in addition, because the data transmitted out of the sending terminal are all encrypted data, the internal data of the sending terminal do not need to be encrypted, supervised and the like, the supervision on the data on the sending terminal can be reduced under the condition of ensuring the data safety, and the data on the sending terminal can be protected quickly.
Referring to fig. 2, fig. 2 is a second flowchart of a data transmission method according to an embodiment of the present application.
The data transmission method provided by the embodiment of the application can comprise the following steps:
step S201: and the server distributes the communication software to the sending terminal and the receiving terminal in a remote distribution mode.
In practical application, on the basis of managing data of a weakened terminal, in order to strengthen the management and control of data transmitted by the terminal and to realize automatic encryption and automatic processing of the data by the terminal, a principle of remote release application may be adopted to perform unified management and control on a communication mode between a sending terminal and a receiving terminal, that is, to perform unified management and control on channels through which data are transmitted by the terminal. Specifically, the server may be used to remotely release the communication software for the sending terminal and the receiving terminal, so that the sending terminal and the receiving terminal apply the communication software released by the server in a remote calling manner, and thus, the server may define a manner in which the sending terminal automatically encrypts data and the receiving terminal automatically processes data through the communication software, and bring the sending terminal and the receiving terminal under the management of the server. In addition, because the communication software applied by the sending terminal and the receiving terminal is remotely issued by the server, the data transmitted by the sending terminal and the receiving terminal need to pass through the server, namely, by means of the technology of remotely issuing the communication software by the server, the data channels of the sending terminal and the receiving terminal can be brought under the server, and the data safety protection of the sending terminal and the receiving terminal on the level of the data channel through the server is realized; in addition, the unified management of the sending terminal and the receiving terminal can be realized only by the server, and the complexity and the difficulty in protecting the data security of the terminal are reduced.
It should be noted that the type of the communication software may be determined according to actual needs, for example, it may be Notes and other mail software, RTX and other IM communication software, and the like. In addition, in order to reduce the influence of the communication software on other applications of the transmitting terminal and the receiving terminal, the transmitting terminal and the receiving terminal may deploy the communication software on themselves in an Application Virtualization (Application Virtualization) manner.
Step S202: the sending terminal acquires target data.
Step S203: and if the target data needs to be transmitted out of the sending terminal, the sending terminal automatically encrypts the target data based on the communication software to obtain encrypted data.
In practical application, the mode that the sending terminal automatically encrypts the target data can be built in the communication software, so that the server can conveniently manage and control the encryption mode of the sending terminal through the communication software.
Step S204: the transmitting terminal transmits the encrypted data to the server based on the communication software.
Step S205: the server transmits the encrypted data to the receiving terminal based on the communication software.
Step S206: if the encrypted data needs to be transmitted into the receiving terminal, the receiving terminal acquires the first security level of the transmitting terminal from the server based on the communication software.
In practical application, the first security level of the sending terminal may be pre-stored in the server, or the sending terminal may send the first security level to the server based on the communication software, so that the receiving terminal can quickly obtain the first security level from the server only based on the communication software.
Step S207: and the receiving terminal automatically processes the encrypted data based on the first security level and the second security level of the receiving terminal in a communication mode to obtain processed data.
Step S208: the receiving terminal transmits the processed data into itself through the communication software.
In a specific application scenario, when the receiving terminal automatically processes the encrypted data based on the first security level and the second security level, whether the first security level is higher than the second security level can be judged, and if yes, the encrypted data is directly used as processing data; whether the first security level is equal to the second security level or not can be judged, if yes, the encrypted data are automatically decrypted to obtain target data, and the target data are used as processing data; and whether the first security level is lower than the second security level or not can be judged, if yes, the encrypted data are automatically decrypted to obtain target data, and the target data are used as processing data.
For ease of understanding, the data transmission method provided in the present application is now described with reference to the system architecture and fig. 3 to 6. Fig. 3 is a schematic diagram of a conventional data transmission method, and fig. 4 is a system architecture diagram of the conventional data transmission method; fig. 5 is a schematic diagram of a data transmission method of the present application, and fig. 6 is a system architecture diagram of the data transmission method of the present application. In fig. 3 to 6, the high-density region indicates a terminal with a high security level, and the low-density region indicates a terminal with a low security level. In fig. 3, the conventional data transmission method does not manage the data transmission channel between the high-density region and the low-density region. In the system architecture diagram shown in fig. 4, the high-density area and the low-density area are isolated by a network and a core switch to ensure the safe transmission of data; the wireless terminal is connected with the core switch through the AR + access device; the central data center performs information interaction with the high-density region and the low-density region through the core switch, and data safety needs to be ensured through a data center safety boundary; the internet data needs to exchange information with the core switch through an internet security boundary. In fig. 5, the data transmission method provided by the present application focuses on the data exchange channel between the high-density area and the low-density area. In fig. 6, the high-density region is connected to the low-density region through the application distribution server and the intranet data center; the Internet data is also connected with the high-density region or the intranet data center through the application release server; the access area is directly connected with the high-density area, and the high-density area can directly provide a physical machine such as a desktop computer and the like for the access area to use or provide a virtual machine for the access area to use.
As can be seen from fig. 3 and 4, in the conventional data transmission method, both file operation and user behavior in the terminal are considered to be untrustworthy, so that a large number of security measures, such as real-time file encryption and decryption, global file monitoring, and the like, need to be applied to the interior of the terminal, which causes additional burden and a series of problems to the terminal. It can be known from fig. 5 and fig. 6 that, in the data transmission method provided in the present application, all behaviors occurring inside the terminal are considered to be trusted, and only the process of leaving the terminal or entering the terminal by data needs to be safely controlled, so that the data leaving the terminal or entering the terminal is safe, and the data inside the terminal does not need to be safely controlled, the control process is convenient and strong, on the basis, in order to improve the control efficiency, a data channel can be further set on the terminal, and the data on the terminal is quickly controlled by controlling the data channel.
