[0076] To make the technical problems, technical solutions and advantages of the present application clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0077] With the advent of the 5G era, short message service needs to be upgraded to rich media message service, which is referred to as 5G message service. The 5G message service not only supports multimedia message interaction between individual users, but also enables industry customers to provide new interactive digital services based on rich media for their users. 5G message is a basic communication service based on 4G network and 5G network for mobile terminal users, which is an upgrade of short multimedia message service under 4G network or 5G network, and is compatible with short multimedia message service

[0078] The existing 5G message transmission, the sender uploads files based on HTTP; and then sends the file address to the receiver through SIP Message signaling. According to whether the receiver is online, two transmission modes are provided: when the receiver 5G message is online, the file content is downloaded using the HTTP protocol according to the SIP Message content; when the receiver 5G message is not online, the user clicks the URL carried in the short message to download through the browser.

[0079] Although the file uploading and downloading both adopt the HTTPS encrypted transmission mode, and the platform adopts the GBA authentication process when uploading or downloading, the receiver's identity is not judged when the receiver downloads the file; for example, the file sent by the sender to a specific receiver a is not judged whether the receiver a receives the file in the receiving process, but any terminal that is online in the 5G message can receive the file.

[0080] In addition, since the SIP protocol is a text protocol, the file information transmitted through the SIP Message is in clear code, and if there is a background monitoring or Trojan program on the terminal, the related SIP signaling can be easily intercepted from the network card of the terminal through TCP dump, the related file download address can be obtained by analyzing the message, and then the download address is forwarded to another 5G message terminal to download through the other terminal, so that the file can be easily obtained;

[0081] In addition, when the receiver 5G message is not online, the system will be converted into a short message + URL link mode to send to the receiver, and if the receiver has a third-party short message monitoring program, the download link can be easily forwarded to other terminals, and then the user file can be obtained. In summary, the existing file transmission method has low file transmission security.

[0082] In order to solve the above problems, the application provides a file transmission method, device, file server and terminal, wherein the method and device are based on the same application concept, and the principles of solving problems are similar, so the implementation of the device and the method can be mutually referred, and the repeated parts will not be described.

[0083] As shown in the flowchart of the file transmission method provided by the embodiment of the application, the method is applied to a file server and includes the following steps. Figure 1

[0084] Step 101: receiving a first request message for requesting to download a target file sent by a first terminal;

[0085] In this step, the first request message supports the HTTP protocol, which can be an HTTPS GET request. ​

[0086] Step 102: transmitting the target file corresponding to the first request message to the first terminal in the case that the first request message carries a preset temporary password, the preset temporary password being assigned to the first terminal by the file server.

[0087] In this step, it is necessary to point out that the file server stores the target file, which is transmitted to the file server by the second terminal.

[0088] Since the preset temporary password is assigned to the first terminal by the file server, when the file server receives the first request message carrying the preset temporary password sent by the first terminal, it is equivalent to the identity authentication of the first terminal. Only the terminal that passes the identity authentication can obtain the target file, thereby improving the security of file transmission.

[0089] The file transmission method of the embodiment of the application receives the first request message for requesting to download the target file sent by the first terminal; in the case that the first request message carries a preset temporary password, the target file corresponding to the first request message is transmitted to the first terminal, the preset temporary password being assigned to the first terminal by the file server. In this way, the file server assigns the preset temporary password to the terminal, so that the preset temporary password is bound to the terminal, thereby ensuring that only the specified terminal, that is, the terminal carrying the preset temporary password in the request, can obtain the file, and further improving the security of file transmission.

[0090] It is necessary to point out that the first request message carries the preset temporary password, which means that the first terminal has obtained the preset temporary password assigned by the file server before sending the first request message. How to realize the file server assigning the preset temporary password can be selected as follows:

[0091] As an optional implementation, before receiving the first request message for requesting to download the target file sent by the first terminal, the method of the embodiment of the application can further include:

[0092] receiving the second request message for requesting to download the target file sent by the first terminal;

[0093] It is necessary to point out that before the first terminal sends the second request message, the first terminal receives the download link of the file address of the target file sent by the message processing device (such as the 5G message center), and generates the second request message for requesting to download the target file after receiving the access operation (such as click input) of the user to the download link. Then, the first terminal sends the second request message to the file server.

[0094] generating a preset temporary password in a case that a target file corresponding to the second request message needs to be downloaded securely;

[0095] It should be noted that whether the target file needs to be downloaded securely can be determined by the indication information stored in the file server. If the stored indication information is security indication information for indicating that the target file needs to be downloaded securely, the target file needs to be downloaded securely. If the stored indication information is indication information for indicating that the target file does not need to be downloaded securely, the target file does not need to be downloaded securely.

[0096] The preset temporary password is sent to the first terminal by the message processing device.

[0097] The step can specifically include:

[0098] The preset temporary password is sent to the message processing device, and the message processing device sends a binary data short message to the first terminal, the binary data short message carrying the preset temporary password.

[0099] It should be noted that the message processing device sends the preset temporary password to the first terminal in the form of a short message. The preset temporary password can be an OTP (One Time Password, one-time password). The short message is not a normal text message, but a binary data short message in a special format.

[0100] Here, the first terminal, i.e. the 5G message terminal, specifies a port to listen to the binary data short message when accessing wirelessly (such as wifi) and obtaining a registration configuration file from the message processing device (such as a 5G message center). The preset temporary password obtained by the first terminal is stored in the first terminal in a manner invisible to the user, and cannot be obtained by third-party software, greatly enhancing the security of file transmission.

[0101] As an optional implementation manner, the method of the embodiment of the application further includes:

[0102] The target file transmitted by the second terminal and security indication information associated with the target file are obtained, the security indication information being used to indicate that the target file needs to be downloaded securely.

[0103] Here, the second terminal can transmit the target file through HTTPS POST signaling. In order to facilitate the file server to subsequently determine whether the target file needs to be downloaded securely, the second terminal can transmit the security indication information associated with the target file (which can be generated by a security marking operation of a user of the second terminal on the transmitted target file) when transmitting the target file. Specifically, the security indication information associated with the target file can be added in the HTTPS POST signaling.

[0104] The file transmission method provided by the embodiment of the present application comprises the following steps: receiving a first request message for requesting to download a target file sent by a first terminal; and transmitting the target file corresponding to the first request message to the first terminal when the first request message carries a preset temporary password, wherein the preset temporary password is assigned to the first terminal by a file server. In this way, the preset temporary password is bound to the terminal by assigning the preset temporary password to the terminal by the file server, so that only the specified terminal, i.e., the terminal carrying the preset temporary password in the request, can obtain the file, thereby improving the security of file transmission.

[0105] As shown in Figure 2 FIG. 1 is a flowchart of a file transmission method provided by an embodiment of the present application, which is applied to a terminal, i.e., a first terminal, and comprises the following steps:

[0106] Step 201: transmitting a first request message for requesting to download a target file to a file server, wherein the first request message carries a preset temporary password, and the preset temporary password is assigned to the first terminal by the file server.

[0107] In this step, the first request message supports HTTP protocol, which can be an HTTPS GET request.

[0108] Here, since the preset temporary password is assigned to the first terminal by the file server, when the file server receives the first request message carrying the preset temporary password sent by the first terminal, it is equivalent to the identity authentication of the first terminal. Only the terminal passing the identity authentication can obtain the target file, thereby improving the security of file transmission.

[0109] Step 202: receiving the target file corresponding to the first request message transmitted by the file server.

[0110] In this step, when the file server determines that the first request message carries the preset temporary password, it transmits the target file corresponding to the first request message to the first terminal. That is, the first terminal receives the target file corresponding to the first request message transmitted by the file server.

[0111] The file transmission method provided by the embodiment of the present application comprises the following steps: transmitting a first request message for requesting to download a target file to a file server, wherein the first request message carries a preset temporary password, and the preset temporary password is assigned to the first terminal by the file server; and receiving the target file corresponding to the first request message transmitted by the file server. In this way, the preset temporary password is bound to the terminal by assigning the preset temporary password to the terminal by the file server, so that only the specified terminal, i.e., the terminal carrying the preset temporary password in the request, can obtain the file, thereby improving the security of file transmission.

[0112] It should be noted that the preset temporary password is carried in the first request message, which indicates that the first terminal has obtained the preset temporary password allocated by the file server before sending the first request message. How to obtain the preset temporary password allocated by the file server can be selected as follows:

[0113] As an optional implementation, before sending the first request message for requesting to download the target file to the file server, the method of the embodiment of the application can further include:

[0114] sending a second request message for requesting to download the target file to the file server, so that the file server generates a preset temporary password in the case that the target file corresponding to the second request message needs to be securely downloaded;

[0115] It should be noted that before this step is performed, the method of the embodiment of the application can further include:

[0116] First, receiving a download link including a file address of the target file sent by a message processing device, the download link being sent by the file server to the message processing device;

[0117] Based on this, sending a second request message for requesting to download the target file to the file server, that is, this step can specifically include:

[0118] generating the second request message for requesting to download the target file in the case that the user performs an access operation on the download link;

[0119] sending the second request message to the file server.

[0120] That is, before the first terminal sends the second request message, the first terminal receives a download link of a file address of the target file sent by a message processing device (such as a 5G message center), and generates the second request message for requesting to download the target file when receiving a user access operation (such as a click input) on the download link. Then, the first terminal sends the second request message to the file server. Then, the file server generates a preset temporary password in the case that the target file corresponding to the second request message needs to be securely downloaded.

[0121] Then, receiving the preset temporary password sent by the message processing device, the preset temporary password being sent by the file server to the message processing device;

[0122] After the above steps are performed, sending a first request message for requesting to download the target file to the file server can include:

[0123] In a case that the preset temporary password sent by the message processing device is received, a first request message for requesting to download the target file is sent to the file server.

[0124] That is, after receiving the preset temporary password, the first terminal reinitiates the first request message for requesting to download the target file, and the first request message carries the preset temporary password.

[0125] As an optional implementation, the receiving of the preset temporary password sent by the message processing device can include:

[0126] Receiving a binary data short message sent by the message processing device, and the binary data short message carries the preset temporary password.

[0127] It should be noted that the message processing device sends the preset temporary password to the first terminal in the form of a short message, and the preset temporary password can be an OTP (One Time Password, one-time password). The short message is not a normal text message, but a binary data short message in a special format.

[0128] Here, the first terminal, i.e., the 5G message terminal, specifies a port to listen to the binary data short message when accessing through wireless (such as wifi) and obtains a registration configuration file from the message processing device (such as a 5G message center). Moreover, the preset temporary password obtained by the first terminal is stored in the first terminal in a manner invisible to the user, and cannot be obtained by third-party software, which greatly enhances the security of file transmission.

[0129] Optionally, the target file is transmitted to the file server by a second terminal, and the target file is associated with security indication information, and the security indication information is used to indicate that the target file needs to be downloaded securely.

[0130] It should be noted that the second terminal can transmit the target file through HTTPS POST signaling. In order to facilitate the file server to subsequently judge whether the target file needs to be downloaded securely, the second terminal can transmit the security indication information associated with the target file (which can be generated by the user of the second terminal through a security marking operation on the transmitted target file) when transmitting the target file. Specifically, the security indication information associated with the target file can be added in the HTTPS POST signaling.

[0131] The file transmission method of the embodiment of the application, by sending a first request message for requesting to download a target file to a file server, the first request message carrying a preset temporary password, the preset temporary password being allocated to the first terminal by the file server; receiving the target file corresponding to the first request message transmitted by the file server, thus, by allocating the preset temporary password to the terminal by the file server, the preset temporary password is bound to the terminal, so as to ensure that only the specified terminal, that is, the terminal carrying the preset temporary password in the request, can obtain the file, thereby improving the security of file transmission.

[0132] The following two embodiments are described from the perspective of interaction between devices, and the implementation process of the file transmission method of the application is specifically described.

[0133] Embodiment one is described with reference to Figure 3

[0134] It should be noted that this embodiment corresponds to the processing mode of the receiving terminal 5G message online. In the figure, UE A is the sender terminal (second terminal), UE B is the receiver terminal (first terminal), and 5GMC is the 5G message center (message processing device).

[0135] S1: UE A selects media content to be sent in the terminal locally;

[0136] S2: UE A selects to send a file including the media content in a secure manner;

[0137] That is, the file including the media content needs to be downloaded securely.

[0138] S3-4: UE A performs GBA authentication and uploads the file to the file server through HTTPS POST; the file server returns an HTTPS 200 OK message to UE A after uploading successfully;

[0139] It should be noted that the HTTPS 200 OK message carries the XML of the file storage location.

[0140] Here, when UE A uploads the file through the HTTPS POST signaling, the indication information can be added in the HTTPS POST signaling, specifically, the indication information can be represented by a preset field, so as to identify that the file needs to be downloaded securely, for the file server to distinguish whether the file transmission needs special processing, that is, whether it needs to be downloaded securely.

[0141] For example, the following field is added:

[0142] x-3gpp-secutity-ft: true.

[0143] Here, the file server receives the file uploaded by UE A, and if the file carries the extension header x-3gpp-secutity-ft: true, the file is marked to indicate that the identity of the receiver needs to be verified before the file can be downloaded.

[0144] S5-6: UE A sends a SIP Message carrying the file address of the file storage to the 5GMC, and the 5GMC returns a 200 OK message after receiving the SIP Message.

[0145] S7-8: The 5GMC sends the SIP Message to UE B, and UE B returns a 200 OK message after receiving the SIP Message.

[0146] S9-12: If UE B chooses to download the file, it initiates HTTPS GET to download the media content. When the file server receives the file download request, it determines that the file needs to be downloaded securely, and then uses a binary data SMS to send an OTP to UE B through the 5GMC.

[0147] It should be noted that the binary data SMS carries the OTP, and the SMS carrying the OTP is not a normal text message, but a special format data message. According to the GSMA RCC.14 protocol, when the 5G message terminal accesses through wifi, it specifies a port to listen to this binary data SMS after obtaining the registration configuration file from the 5GMC.

[0148] Here, after the file server receives the file download request, it sends a 200 OK message with empty content to UE B. At this time, UE B receives the 200 OK message with empty content and does not make further processing, but waits to receive the binary data SMS carrying the OTP.

[0149] S13-14: UE B receives the SMS and automatically intercepts the OTP, and reinitiates the HTTPS request to download the file, which carries the OTP information.

[0150] S15-18: After successful download, UE B sends a message receipt.

[0151] Example Two Reference Figure 4

[0152] It should be noted that this embodiment corresponds to the processing method of the receiver terminal 5G message offline. In the figure, UE A is the sender terminal (second terminal), UE B is the receiver terminal (first terminal), and 5GMC is the 5G message center (message processing device).

[0153] S1001: UE A selects media content to be sent in terminal locally;

[0154] S1002: UE A selects to send file including the media content in a secure way;

[0155] That is, the file including the media content needs to be downloaded securely.

[0156] S1003-1004: UE A performs GBA authentication and uploads the file to the file server through HTTPS POST; the file server returns HTTPS 200 OK message to UE A after uploading successfully;

[0157] It should be noted that the HTTPS 200 OK message carries the XML of the file storage location.

[0158] Here, when UE A uploads the file through HTTPS POST signaling, the indication information can be added in the HTTPS POST signaling, specifically, the indication information can be represented by a preset field, so as to identify that the file needs to be downloaded securely, for making the file server distinguish whether the file transmission needs special processing, that is, whether it needs to be downloaded securely.

[0159] For example, the following field is added:

[0160] x-3gpp-secutity-ft: true.

[0161] Here, when the file server receives the file uploaded by UE A, if it finds that the file carries the extension header x-3gpp-secutity-ft: true, the file is marked to indicate that the identity of the receiver needs to be verified before the file can be downloaded.

[0162] S1005-1006: UE A sends SIP Message carrying the file address of the file storage to 5GMC, and 5GMC returns 200 OK message after receiving the SIP Message;

[0163] S1007-1008: When 5GMC determines that UE B is not online, it sends the file address of the file storage to UE B through SMS+URL, and UE B returns 200 OK message after receiving the message;

[0164] S1009-1012: If UE B clicks the URL in the SMS to download the file, HTTPS GET is started to download the media content; when the file server receives the file download request, it determines that the file needs to be downloaded securely, and then uses binary data short message to send OTP to UE B through 5GMC.

[0165] It should be noted that the binary data message carries the OTP, and the message carrying the OTP is not a normal text message, but a special format data message. According to the GSMA RCC.14 protocol, when a 5G message terminal accesses through WiFi, the terminal specifies a port to listen to the binary data message when obtaining a registration configuration file in 5GMC.
