具体实施方式Detailed ways

这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with aspects of the disclosure as detailed in the appended claims.

在本公开使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "the" and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise. It will also be understood that the term "and/or" as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

应当理解，尽管在本公开可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various information, the information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present disclosure, the first information may also be called second information, and similarly, the second information may also be called first information. Depending on the context, the word "if" as used herein may be interpreted as "when" or "when" or "in response to determining."

近年来，不同终端设备之间的数据交互形式越来越多，例如投屏连接等。投屏连接的场景下，一个终端设备将其视频、音频等数据通过录屏、录音等方式保存成多帧数据，再通过有线连接或无线连接的方式传输到另一个终端设备，另一个终端设备则可以对多帧数据进行解析后得到原视频、音频等数据，进而对其进行显示或播放等展示操作。在两个终端设备之间持续传输大量数据的过程中，数据存在被恶意应用截取的可能，即数据交互的安全性较差，如果这些数据中包含用户的通话数据、联系人、账号密码等，可能会导致这些信息的泄露，严重影响用户的个人信息安全。In recent years, there have been more and more forms of data interaction between different terminal devices, such as screen projection connections. In the scenario of screen casting connection, one terminal device saves its video, audio and other data into multi-frame data through screen recording, audio recording, etc., and then transmits it to another terminal device through wired connection or wireless connection, and the other terminal device Then you can parse the multi-frame data to obtain the original video, audio and other data, and then perform display operations such as display or playback. During the continuous transmission of large amounts of data between two terminal devices, the data may be intercepted by malicious applications, that is, the security of data interaction is poor. If the data contains the user's call data, contacts, account passwords, etc., It may lead to the leakage of this information and seriously affect the security of users' personal information.

为了保证数据交互的安全性，相关技术中，一个终端设备在传输数据前对数据进行加密处理，另一个终端设备在接收到数据后再对数据进行解密处理。但是上述加密解密的过程不仅会降低数据交互的效率，还会增加终端设备的运算负荷。以投屏连接的场景为例，上述加密和加密的过程会会大大降低视频、音频传输的效率，造成视频画面的卡顿或者模糊，以及音频卡顿或者失真等问题。而且如果截取交互数据的恶意应用具有解密能力，则会还续获取交互数据并解密，造成重要信息的持续泄露，对数据安全的影响较大。In order to ensure the security of data interaction, in related technologies, one terminal device encrypts the data before transmitting the data, and the other terminal device decrypts the data after receiving the data. However, the above-mentioned encryption and decryption process will not only reduce the efficiency of data interaction, but also increase the computing load of the terminal device. Taking the screen-casting connection scenario as an example, the above-mentioned encryption and encryption processes will greatly reduce the efficiency of video and audio transmission, causing problems such as stuck or blurred video images, and audio stuck or distortion. Moreover, if the malicious application that intercepts the interactive data has the decryption capability, it will continue to obtain and decrypt the interactive data, causing the continuous leakage of important information and having a greater impact on data security.

基于此，第一方面，本公开至少一个实施例提供了一种数据交互方法，请参照附图1，其示出了该方法的流程，包括步骤S101和步骤S103。Based on this, in the first aspect, at least one embodiment of the present disclosure provides a data interaction method. Please refer to FIG. 1 , which shows the flow of the method, including step S101 and step S103.

其中，该方法可以应用于第一终端设备，所述第一终端与第二终端进行投屏交互。第一终端设备可以为用户设备(User Equipment，UE)、移动设备、用户终端、终端、蜂窝电话、无绳电话、个人数字处理(Personal Digital Assistant，PDA)手持设备、计算设备、可穿戴设备等。第一终端设备可以为数据交互场景下的数据源头，也就是向外发送数据的一侧，例如智能手机向电视机投屏的场景下，智能手机为数据源头，电视机为数据终点。Wherein, this method can be applied to a first terminal device, and the first terminal and the second terminal perform screen projection interaction. The first terminal device may be a user equipment (User Equipment, UE), a mobile device, a user terminal, a terminal, a cellular phone, a cordless phone, a personal digital assistant (Personal Digital Assistant, PDA) handheld device, a computing device, a wearable device, etc. The first terminal device can be the data source in a data interaction scenario, that is, the side that sends data outward. For example, in a scenario where a smartphone projects a screen to a TV, the smartphone is the data source and the TV is the data destination.

可以理解的是，可以由第一终端设备的特定应用程序或特定模块等来执行该方法。例如，可以按照附图2，作为第一终端设备的终端A具有用于数据交互的应用C，应用C可以与应用1、应用2、应用3等其他应用程序通信连接，从而向其他应用程序获取音频数据、视频数据等交互数据，并对这些交互数据进行封装并发送至作为第二终端设备的终端B，终端B是数据交互的数据终点，其可以接收应用C发送的数据，并对接收的数据进行解封装，同时还能够反控终端A的应用，即向应用C发送控制指令，然后应用C将这些控制指令发送至对应的应用程序。这些其他应用程序可以为音乐类应用程序、视频类应用程序、导航类应用程序、社交类应用程序等。It can be understood that the method may be executed by a specific application program or a specific module of the first terminal device, or the like. For example, according to Figure 2, terminal A as the first terminal device has application C for data interaction. Application C can communicate and connect with other application programs such as application 1, application 2, application 3, etc., thereby obtaining information from other application programs. Interactive data such as audio data, video data, etc. are encapsulated and sent to Terminal B as the second terminal device. Terminal B is the data end point of data interaction. It can receive the data sent by Application C and process the received data. The data is decapsulated, and at the same time, the application of terminal A can be counter-controlled, that is, control instructions are sent to application C, and then application C sends these control instructions to the corresponding application. These other applications may be music applications, video applications, navigation applications, social applications, etc.

在步骤S101中，获取交互数据中的关键数据，并将所述关键数据封装为M个第一数据包，其中，M为大于1的自然数。In step S101, key data in the interaction data is obtained, and the key data is encapsulated into M first data packets, where M is a natural number greater than 1.

其中，交互数据为数据交互所针对的数据，也就是第一终端设备向第二终端设备所发送的数据。以投屏场景为例，交互数据为视频、音频等数据。关键数据可以为涉及到用户隐私或者账户安全的数据。The interaction data is data targeted by data interaction, that is, data sent by the first terminal device to the second terminal device. Taking the screencasting scenario as an example, the interactive data is video, audio and other data. Key data can be data related to user privacy or account security.

在数据交互的过程中，第一终端设备可以根据交互控制指令确定交互数据，以及交互数据所属的应用程序，并向交互数据所属的应用程序获取所述交互数据，其中，所述交互控制指令基于用户对所述第一终端设备或所述第二终端设备的操作生成。以投屏场景为例，在第一终端设备和第二终端设备建立投屏连接后，第一终端设备会将默认画面发送至第二终端设备，以使第二终端设备显示该默认画面，该默认画面可以为第一终端设备的当前画面、桌面或者投屏程序的专用初始画面；接下来，用户可以对第一终端设备进行操作，则第一终端设备基于该操作生成交互控制指令，或者对第二终端设备上显示的上述默认画面进行操作，第二终端设备基于该操作生成交互控制指令并将该交互控制指令发送至第一终端设备，第一终端设备根据该交互控制指令向对应的应用程序获取画面、音频等数据，例如交互控制指令是启动桌面上的某个应用程序，则第一终端设备启动该应用程序，并获取该应用程序启动后的初始界面作为交互数据。During the process of data interaction, the first terminal device can determine the interaction data and the application program to which the interaction data belongs according to the interaction control instruction, and obtain the interaction data from the application program to which the interaction data belongs, wherein the interaction control instruction is based on Generated by a user's operation on the first terminal device or the second terminal device. Taking the screencasting scenario as an example, after the first terminal device and the second terminal device establish a screencasting connection, the first terminal device will send the default screen to the second terminal device so that the second terminal device displays the default screen. The default screen can be the current screen of the first terminal device, the desktop, or the dedicated initial screen of the screen projection program; next, the user can operate the first terminal device, and the first terminal device generates an interactive control instruction based on the operation, or The second terminal device operates on the above-mentioned default screen displayed on the second terminal device. The second terminal device generates an interactive control instruction based on the operation and sends the interactive control instruction to the first terminal device. The first terminal device sends a request to the corresponding application according to the interactive control instruction. The program obtains picture, audio and other data. For example, if the interactive control instruction is to start an application on the desktop, then the first terminal device starts the application and obtains the initial interface after the application is started as the interaction data.

第一终端设备在获取交互数据后，可以按照下述方式确定该交互数据中是否存在关键数据：首先，确定所述交互数据中是否存在属于预设关键数据列表的数据，示例性的，第一终端设备内预先设置了预设关键数据列表；接下来，在所述交互数据中存在属于预设关键数据列表的数据的情况下，确定所述交互数据中存在关键数据，并确定所述交互数据中，属于所述预设关键数据列表的数据为关键数据；在所述交互数据中不存在预设关键数据列表中的数据的情况下，确定所述交互数据中不存在关键数据。After acquiring the interaction data, the first terminal device can determine whether there is key data in the interaction data in the following manner: first, determine whether there is data belonging to the preset key data list in the interaction data. For example, first A preset key data list is preset in the terminal device; next, if there is data belonging to the preset key data list in the interaction data, it is determined that key data exists in the interaction data, and the interaction data is determined , the data belonging to the preset key data list is key data; when there is no data in the preset key data list in the interaction data, it is determined that there is no key data in the interaction data.

在所述交互数据中存在关键数据的情况下，可以执行本步骤，即获取所述交互数据中的关键数据。由于受到传输通道带宽的影响，关键数据无法直接传输至第二终端设备，因此可以参照附图3，将关键数据封装为M个第一数据包。In the case where key data exists in the interaction data, this step can be performed, that is, obtaining the key data in the interaction data. Due to the influence of the bandwidth of the transmission channel, the key data cannot be directly transmitted to the second terminal device. Therefore, the key data can be encapsulated into M first data packets with reference to Figure 3.

另外，还可以获取所述交互数据中的非关键数据，并将关键数据封装为多个第二数据包，以及将所述多个第二数据包发送至所述第二终端设备，以使所述第二终端设备解析并展示所述非关键数据。In addition, non-critical data in the interactive data can also be obtained, the critical data can be encapsulated into a plurality of second data packets, and the plurality of second data packets can be sent to the second terminal device, so that all The second terminal device parses and displays the non-critical data.

在所述交互数据中不存在关键数据的情况下，可以将交互数据封装为多个第三数据包，以及将所述多个第三数据包发送至所述第二终端设备，以使所述第二终端设备解析并展示所述交互数据。When there is no key data in the interaction data, the interaction data may be encapsulated into a plurality of third data packets, and the plurality of third data packets may be sent to the second terminal device, so that the The second terminal device parses and displays the interaction data.

在步骤S102中，将所述M个第一数据包中N个第一数据包进行加密处理，并依次发送所述M个第一数据包至第二终端设备，其中，N大于等于1，且小于M。In step S102, N first data packets among the M first data packets are encrypted, and the M first data packets are sent to the second terminal device in sequence, where N is greater than or equal to 1, and Less than M.

其中，进行加密处理的第一数据包可以为所述M个第一数据包中的部分。示例性的，可以先根据所述第一终端设备的计算力p和数据传输链路的质量参数q，确定所述加密比例K，第一终端设备的计算力p可以用于表征第一终端设备的加密速度，数据传输链路的质量参数q可以用于表征丢包率，如果丢包率过高则可能会造成加密的第一数据包丢失，进而造成加密无意义，以投屏场景为例，丢包率极低，q的值在0.98-1之间，例如可以按照下述公式计算K：K＝p*q；然后根据所述M和加密比例K，确定加密数量N，例如可以按照下述公式计算N：N＝M*K；最后将所述多个第一数据包中的前N个第一数据包进行加密处理。可以参照附图4，关键数据被封装为4个第一数据包后，前3个第一数据包被加密。可以理解的是，附图4仅为实例，一般加密比例K 在20％-30％之间。The first data packet to be encrypted may be part of the M first data packets. For example, the encryption ratio K can be determined first based on the computing power p of the first terminal device and the quality parameter q of the data transmission link. The computing power p of the first terminal device can be used to characterize the first terminal device. The encryption speed, the quality parameter q of the data transmission link can be used to characterize the packet loss rate. If the packet loss rate is too high, the first encrypted data packet may be lost, which will make the encryption meaningless. Take the screen projection scenario as an example. , the packet loss rate is extremely low, and the value of q is between 0.98-1. For example, K can be calculated according to the following formula: K = p*q; then according to the M and the encryption ratio K, the encryption number N is determined, for example, according to The following formula is used to calculate N: N=M*K; finally, the first N first data packets among the plurality of first data packets are encrypted. Referring to Figure 4, after key data is encapsulated into four first data packets, the first three first data packets are encrypted. It can be understood that Figure 4 is only an example, and the general encryption ratio K is between 20% and 30%.

在一个可能的实施例中，可以按照如图5所示的方式对第一数据包进行加密处理：将加密标识F、加密信息I和第一数据包进行加密处理，得到加密后的第一数据包，其中，所述加密标识F用于第二终端设备从所述多个第一数据包中确定经过加密处理的第一数据包。In a possible embodiment, the first data packet can be encrypted as shown in Figure 5: the encryption identifier F, the encryption information I and the first data packet are encrypted to obtain the encrypted first data. package, wherein the encryption identifier F is used by the second terminal device to determine the encrypted first data packet from the plurality of first data packets.

可以理解的是，在数据交互的过程中，第一终端设备会持续的根据交互控制指令获取交互数据，并判断交互数据中是否存在关键数据，若存在关键数据则对关键数据封装得到的多个第一数据包中的部分或全部进行加密后发送到第二终端设备，并对非关键数据封装得到的多个第二数据包直接发送至第二终端设备，若不存在关键数据则直接将交互数据封装后得到的多个第三数据包发送至第二终端设备。可以根据获取交互数据的顺序确定上述交互数据的处理和发送顺序。It can be understood that during the process of data interaction, the first terminal device will continuously obtain the interaction data according to the interaction control instructions, and determine whether there is key data in the interaction data. If there is key data, the key data will be encapsulated into multiple Part or all of the first data packet is encrypted and sent to the second terminal device, and the multiple second data packets obtained by encapsulating non-critical data are directly sent to the second terminal device. If there is no critical data, the interaction is directly The plurality of third data packets obtained after data encapsulation are sent to the second terminal device. The order of processing and sending the above interactive data can be determined according to the order in which the interactive data is obtained.

在步骤S103中，接收到所述第二终端设备返回的加密信息，根据所述加密信息确定是否继续发送所述交互数据，其中，所述加密信息由所述第二终端设备对经过加密处理的第一数据包进行解密得到。In step S103, the encrypted information returned by the second terminal device is received, and whether to continue sending the interactive data is determined according to the encrypted information, wherein the encrypted information is used by the second terminal device to encrypt the encrypted information. The first data packet is decrypted and obtained.

其中，第二终端设备在数据交互过程中持续接收第一终端设备以数据包的形式所发送的交互数据，然后依次对接收到的交互数据进行处理，即依次对接收到的数据包进行处理。在处理数据包前，可以查看数据包是否具有加密标识，若不具有加密标识，则该数据包为第二数据包、第三数据包或未经加密处理的第一数据包，若具有加密标识，则该数据包为经过加密的第一数据包。The second terminal device continues to receive the interaction data sent by the first terminal device in the form of data packets during the data interaction process, and then processes the received interaction data in sequence, that is, processes the received data packets in sequence. Before processing the data packet, you can check whether the data packet has an encryption identifier. If it does not have an encryption identifier, the data packet is the second data packet, the third data packet, or the first data packet that has not been encrypted. If it has an encryption identifier, , then the data packet is the encrypted first data packet.

在接收第一终端设备发送的多个第二数据包之后，可以按照接收顺序依次对所述多个第二数据包进行解析处理，得到所述非关键数据，并按照所述非关键数据的展示方式，对所述非关键数据进行展示。示例性的，非关键数据为画面，则可以对图像进行显示；非关键数据为视频，则可以对视频进行播放。After receiving a plurality of second data packets sent by the first terminal device, the plurality of second data packets can be parsed in sequence according to the order of reception, to obtain the non-critical data, and display the non-critical data according to the method to display the non-critical data. For example, if the non-key data is a picture, the image can be displayed; if the non-key data is a video, the video can be played.

在接收第一终端设备发送的多个第三数据包之后，可以按照接收顺序依次对所述多个第三数据包进行解析处理，得到所述交互数据，并按照所述交互数据的展示方式，对所述交互数据进行展示。示例性的，交互数据为画面，则可以对图像进行显示；交互数据为视频，则可以对视频进行播放。After receiving a plurality of third data packets sent by the first terminal device, the plurality of third data packets may be parsed and processed in sequence according to the reception order to obtain the interactive data, and according to the display method of the interactive data, Display the interactive data. For example, if the interactive data is a picture, the image can be displayed; if the interactive data is a video, the video can be played.

在接收第一终端设备发送的多个第一数据包之后，可以先将所述多个第一数据包中具有加密标识的第一数据包，确定为经过加密处理的第一数据包，然后对经过加密处理的所述N个第一数据包进行解密处理，得到加密信息和解密后的第一数据包，然后按照接收顺序依次对所述多个第一数据包进行解析处理，得到所述关键数据，并按照所述关键数据的展示方式，对所述关键数据进行展示，示例性的，关键数据为画面，则可以对图像进行显示；关键数据为视频，则可以对视频进行播放；同时可以将加密信息发送至第一终端设备。After receiving a plurality of first data packets sent by the first terminal device, the first data packet with an encryption identifier among the plurality of first data packets may first be determined as the encrypted first data packet, and then the first data packet may be The N first data packets that have been encrypted are decrypted to obtain the encrypted information and the decrypted first data packets, and then the multiple first data packets are parsed in sequence according to the order of reception to obtain the key data, and display the key data according to the display method of the key data. For example, if the key data is a picture, the image can be displayed; if the key data is a video, the video can be played; at the same time, Send the encrypted information to the first terminal device.

第一终端设备在预设时长内接收到所述第二终端设备返回的加密信息，且所述加密信息通过验证的情况下，继续发送所述交互数据，即继续以数据包的形式发送存在关键数据的交互数据中的关键数据和非关键数据，以及不存在关键数据的交互数据；否则(即第一终端设备未在预设时长内接收到所述第二终端设备返回的加密信息，或第一终端设备在预设时长内接收到所述第二终端设备返回的加密信息，但加密信息未通过验证的情况下)，停止发送交互数据，即停止以发送存在关键数据的交互数据中的关键数据和非关键数据，以及不存在关键数据的交互数据，例如，在投屏场景下，可以停止投屏，断开与第二终端设备间的投屏连接。If the first terminal device receives the encrypted information returned by the second terminal device within the preset time period, and the encrypted information passes the verification, it will continue to send the interactive data, that is, continue to send the existence key in the form of data packets. Key data and non-key data in the interactive data of the data, as well as interactive data without critical data; otherwise (that is, the first terminal device does not receive the encrypted information returned by the second terminal device within the preset time period, or the first terminal device does not receive the encrypted information returned by the second terminal device within the preset time period, or the When a terminal device receives the encrypted information returned by the second terminal device within a preset time period, but the encrypted information fails to pass verification), it stops sending interactive data, that is, it stops sending key interactive data in which critical data exists. Data and non-critical data, as well as interactive data without critical data. For example, in a screencasting scenario, you can stop screencasting and disconnect the screencasting connection with the second terminal device.

可以理解的是，第一终端设备在第一终端设备未在预设时长内接收到所述第二终端设备返回的加密信息，或第一终端设备在预设时长内接收到所述第二终端设备返回的加密信息，但加密信息未通过验证的情况下，还可以生成提示信息，例如显示在显示屏上的文字提示信息，或由扬声器播放的音频提示信息。It can be understood that the first terminal device does not receive the encrypted information returned by the second terminal device within the preset time period, or the first terminal device receives the encrypted information returned by the second terminal device within the preset time period. If the device returns encrypted information, but the encrypted information fails to pass verification, it can also generate prompt information, such as text prompt information displayed on the display, or audio prompt information played by the speaker.

本公开通过获取交互数据中的关键数据，并将关键数据封装为M个第一数据包，然后可以将所述M个第一数据包中N个第一数据包进行加密处理，并依次发送所述M个第一数据包至第二终端设备，最后接收所述第二终端设备返回的加密信息，根据所述加密信息确定是否继续发送所述交互数据，其中，所述加密信息由所述第二终端设备对经过加密处理的第一数据包进行解密得到。由于对交互数据中的关键数据所封装的M个第一数据包中N个第一数据包进行了加密处理，因此可以在M个数据包发送至第二终端设备后，根据第二终端设备是否返回了能够通过验证的加密信息，来判断第二终端设备是否成功解密了被加密的第一数据包，进而能够判断发送至第二终端设备的数据是否安全，并在不安全的情况停止发送交互数据，从而避免数据泄露，保证数据安全。This disclosure obtains the key data in the interactive data and encapsulates the key data into M first data packets. Then, the N first data packets among the M first data packets can be encrypted and sent in sequence. The M first data packets are sent to the second terminal device, and finally the encrypted information returned by the second terminal device is received, and whether to continue sending the interactive data is determined according to the encrypted information, wherein the encrypted information is provided by the third terminal device. The second terminal device decrypts the encrypted first data packet to obtain the encrypted data packet. Since the N first data packets among the M first data packets encapsulated by the key data in the interactive data are encrypted, after the M data packets are sent to the second terminal device, the second terminal device can be encrypted according to whether the second terminal device Encrypted information that can pass verification is returned to determine whether the second terminal device has successfully decrypted the encrypted first data packet, and then can determine whether the data sent to the second terminal device is safe, and stop sending interactions if it is unsafe. data, thereby avoiding data leakage and ensuring data security.

本公开中，对封装得到的多个第一数据包中的部分进行加密处理，从而可以降低第一终端设备的加密处理的运算负荷，以及第二终端设备的解密处理的运算负荷，从而避免出现卡顿和断流的问题。而且本公开的进一步根据第二终端设备对加密的第一数据包的解密情况，来控制第一终端设备后续的数据交互，即在第二终端设备对加密的第一数据包成功解密的情况下继续进行数据交互，在第二终端设备对加密的第一数据包未成功解密的情况下停止进行数据交互，从而避免了第二终端设备中的恶意应用虽然不能够解密经过加密处理的第一数据包，但依然可以继续获取未经过加密处理的第一数据包而造成的用户信息泄露。再者本公开将多个第一数据包中的前N个第一数据包进行加密，能够在存在恶意应用截取数据的情况下避免后续未加密的数据包被截取，最大程度的保证了数据安全。In the present disclosure, some of the encapsulated first data packets are encrypted, thereby reducing the computational load of the encryption process of the first terminal device and the computational load of the decryption process of the second terminal device, thereby avoiding the occurrence of Problems with lags and interruptions. Moreover, the present disclosure further controls the subsequent data interaction of the first terminal device based on the decryption of the encrypted first data packet by the second terminal device, that is, when the second terminal device successfully decrypts the encrypted first data packet. Continue data interaction, and stop data interaction if the second terminal device fails to decrypt the encrypted first data packet, thereby avoiding the possibility that a malicious application in the second terminal device cannot decrypt the encrypted first data. package, but it is still possible to continue to obtain the first data package that has not been encrypted, resulting in the leakage of user information. Furthermore, the present disclosure encrypts the first N first data packets among multiple first data packets, which can prevent subsequent unencrypted data packets from being intercepted when there is a malicious application intercepting data, thus ensuring data security to the greatest extent. .

第二方面，本公开至少一个实施例提供了一种数据交互方法，请参照附图6，其示出了该方法的流程，包括步骤S601和步骤S503。In the second aspect, at least one embodiment of the present disclosure provides a data interaction method. Please refer to FIG. 6 , which shows the flow of the method, including step S601 and step S503.

其中，该方法可以应用于第二终端设备。第二终端设备可以为电视机、车载终端等。第二终端设备可以为数据交互场景下的数据终点，也就是接收数据的一侧，例如智能手机向电视机投屏的场景下，智能手机为数据源头，电视机为数据终点。Wherein, the method can be applied to the second terminal device. The second terminal device may be a television, a vehicle-mounted terminal, etc. The second terminal device can be the data destination in a data interaction scenario, that is, the side that receives data. For example, in a scenario where a smartphone projects a screen to a TV, the smartphone is the data source and the TV is the data destination.

M is a natural number greater than 1, and N is greater than or equal to 1 and less than M.

本步骤中第一终端设备对关键数据的获取、封装、加密、发送等操作已经在第一方面的实施例中进行了详细的介绍，因此这里不再重复赘述。In this step, the operations of obtaining, encapsulating, encrypting, and sending key data by the first terminal device have been described in detail in the embodiment of the first aspect, so the details will not be repeated here.

在步骤S602中，对经过加密处理的所述N个第一数据包进行解密处理，得到加密信息。In step S602, the N first data packets that have been encrypted are decrypted to obtain encrypted information.

首先，可以将所述M个第一数据包中具有加密标识的第一数据包，确定为经过加密处理的第一数据包，接下来，对经过加密处理的第一数据包进行解密处理。解密后，不仅得到了解密后的第一数据包，还得到了第一终端设备在解密出来过程中加入的加密信息。First, the first data packet with the encryption identifier among the M first data packets may be determined as the encrypted first data packet. Next, the encrypted first data packet may be decrypted. After decryption, not only the decrypted first data packet is obtained, but also the encrypted information added by the first terminal device during the decryption process is obtained.

在对经过加密处理的所述N个第一数据包进行解密处理之后，可以按照接收顺序依次对所述M个第一数据包进行解析处理，得到所述关键数据，并按照所述关键数据的展示方式，对所述关键数据进行展示。示例性的，非关键数据为画面，则可以对图像进行显示；非关键数据为视频，则可以对视频进行播放。After decrypting the encrypted N first data packets, the M first data packets can be parsed in sequence according to the receiving order to obtain the key data, and according to the key data Display method to display the key data. For example, if the non-key data is a picture, the image can be displayed; if the non-key data is a video, the video can be played.

在步骤S603中，将所述加密信息发送至所述第一终端设备，以使所述第一终端设备继续发送所述交互数据。In step S603, the encrypted information is sent to the first terminal device, so that the first terminal device continues to send the interaction data.

本步骤中第一终端设备对加密信息的接收、验证以及根据验证结果进行的继续或停止发送交互数据等操作，已经在第一方面的实施例中进行了详细的介绍，因此这里不再重复赘述。In this step, operations such as receiving and verifying the encrypted information by the first terminal device and continuing or stopping sending interactive data based on the verification results have been described in detail in the embodiment of the first aspect, so the details will not be repeated here. .

另外，第二终端设备还可以接收第一终端设备发送的多个第二数据包，其中，所述多个第二数据包由所述第一终端设备对交互数据中的非关键数据进行封装得到；并按照接收顺序依次对所述多个第二数据包进行解析处理，得到所述非关键数据；以及按照所述非关键数据的展示方式，对所述非关键数据进行展示。示例性的，非关键数据为画面，则可以对图像进行显示；非关键数据为视频，则可以对视频进行播放。In addition, the second terminal device may also receive a plurality of second data packets sent by the first terminal device, wherein the plurality of second data packets are obtained by the first terminal device encapsulating non-critical data in the interactive data. ; and sequentially parse and process the plurality of second data packets according to the order of reception to obtain the non-critical data; and display the non-critical data according to the display method of the non-critical data. For example, if the non-key data is a picture, the image can be displayed; if the non-key data is a video, the video can be played.

另外，第二终端设备还可以接收第一终端设备发送的多个第三数据包，其中，所述多个第三数据包由所述第一终端设备对不存在关键数据的交互数据进行封装得到；并按照接收顺序依次对所述多个第三数据包进行解析处理，得到所述交互数据；以及按照所述交互数据的展示方式，对所述交互数据进行展示。示例性的，非关键数据为画面，则可以对图像进行显示；非关键数据为视频，则可以对视频进行播放。In addition, the second terminal device may also receive a plurality of third data packets sent by the first terminal device, wherein the plurality of third data packets are obtained by the first terminal device encapsulating interactive data without critical data. ; and sequentially parse and process the plurality of third data packets according to the order of reception to obtain the interactive data; and display the interactive data according to the display method of the interactive data. For example, if the non-key data is a picture, the image can be displayed; if the non-key data is a video, the video can be played.

可以参照附图7，其示出了作为第二终端设备的终端B在接收到交互数据后的处理流程。终端B收到数据后，首先确定是否需要解密；若不需要解密，即数据为存在关键数据的交互数据中的非关键数据，或不存在关键数据的交互数据，则解析数据并展示；若需要解密，则对数据进行加密，并对解密的数据进行解析并展示，同时解密过程中获取加密信息I，然后将加密信息I发送到作为第一终端设备的终端A，终端A确定信息I是否正确，若正确(即通过验证)则继续发送数据，若不正确(即未通过验证)则终止发送数据。Reference may be made to FIG. 7 , which shows the processing flow of terminal B as the second terminal device after receiving interactive data. After receiving the data, terminal B first determines whether decryption is required; if decryption is not required, that is, the data is non-critical data in the interactive data where critical data exists, or interactive data where critical data does not exist, the data will be parsed and displayed; if necessary To decrypt, the data is encrypted, and the decrypted data is parsed and displayed. At the same time, the encrypted information I is obtained during the decryption process, and then the encrypted information I is sent to terminal A as the first terminal device. Terminal A determines whether the information I is correct. , if it is correct (that is, it passes the verification), it will continue to send the data, if it is incorrect (that is, it does not pass the verification), it will stop sending the data.

基于第二终端设备对交互数据的展示，用户可以对交互数据的展示结果进行操作，例如对第二终端设备显示的投屏界面进行操作；第二终端设备则可以基于用户对所述交互数据的展示结果的操作，生成交互控制指令，并将所述交互控制指令发送至所述第一终端设备，以使所述终端设备继续返回所述交互数据。Based on the display of the interactive data by the second terminal device, the user can operate on the display result of the interactive data, such as operating the screen projection interface displayed by the second terminal device; the second terminal device can then operate on the display result of the interactive data based on the user's display of the interactive data. The operation of displaying the results generates an interaction control instruction, and sends the interaction control instruction to the first terminal device, so that the terminal device continues to return the interaction data.

可以将上述两个方面介绍的数据交互方法进行结合，得到下述数据交互方法。在该数据交互方法中，第一终端设备持续的，根据交互控制指令(所述交互控制指令基于用户对所述第一终端设备或所述第二终端设备的操作生成)获取交互数据，并将交互数据封装后发送至第二终端设备，第二终端设备接收到交互数据后进行解封装，然后进行展示，例如显示画面和播放音视频等。在上述交互数据中存在关键数据，关键数据涉及用户隐私或者账号信息，因此需要加密进行保护，因此在对关键数据进行封装后，对得到的多个第一数据包中的部分进行加密，然后发送到第二终端设备，第二终端设备接收到加密的第一数据包需要先进行解密，然后解封装，再进行展示。同时，关键数据中的加密的第一数据包还作为数据交互过程中的安全性验证手段，即第一数据包在加密过程中加入了加密信息，而第二终端设备在解密后会得到该加密信息，并将该加密信息返回至第一终端设备，因此第一终端设备接收到正确的加密信息则表示目前交互过程安全，可以继续进行数据交互，第一终端设备未接收到正确的加密信息则表示目前交互过程不安全，可以停止进行数据交互。The data interaction methods introduced in the above two aspects can be combined to obtain the following data interaction method. In this data interaction method, the first terminal device continuously obtains interaction data according to the interaction control instructions (the interaction control instructions are generated based on the user's operation of the first terminal device or the second terminal device), and The interactive data is encapsulated and sent to the second terminal device. After receiving the interactive data, the second terminal device decapsulates the data and then displays it, such as displaying pictures and playing audio and video. There is key data in the above interactive data. The key data involves user privacy or account information, so it needs to be encrypted for protection. Therefore, after the key data is encapsulated, parts of the multiple first data packets obtained are encrypted and then sent. To the second terminal device, the second terminal device receives the encrypted first data packet and needs to first decrypt it, then decapsulate it, and then display it. At the same time, the encrypted first data packet in the key data also serves as a security verification method during the data interaction process. That is, the first data packet adds encrypted information during the encryption process, and the second terminal device will obtain the encrypted information after decryption. information and returns the encrypted information to the first terminal device. Therefore, if the first terminal device receives the correct encrypted information, it means that the current interaction process is safe and data interaction can continue. If the first terminal device does not receive the correct encrypted information, then Indicates that the current interaction process is unsafe and data interaction can be stopped.
