[0002] With the development of science and technology, smart terminals based on the fifth generation of mobile communications (5G) continue to highlight their important role in various application scenarios. While people enjoy the convenience of ultra-high-speed networks brought by smart terminals of the fifth generation of mobile communications (5G), they cannot ignore the potential safety hazards of smart terminals of the fifth generation of mobile communications (5G). At the same time, due to their low latency and high speed, smart terminals of the fifth generation of mobile communications (5G) are particularly suitable for ultra-high-definition video, Internet of Vehicles, networked drones, telemedicine, smart electricity, smart factories, smart security, personal AI assistants and other fields, and these fields have extremely high security requirements.

[0003] One solution to the current communication security issues between 5G smart terminals is to implement encryption and decryption through software algorithms. This can solve security issues for low-latency and medium-speed application scenarios, but the speed of software encryption and decryption cannot meet the requirements for applications with extremely low latency requirements (such as telemedicine) and extremely high speed requirements (ultra-high-definition video). Another solution is to use TF cryptographic cards for encryption, but the encryption speed of TF cryptographic cards is also limited and cannot meet the high-speed requirements of 5G networks.

[0004] In order to overcome the defects of the above-mentioned prior art, the present invention provides a 5G encrypted smart terminal. Summary of the invention

If the parsing determines that the control instruction or data is sent to the communication module, the encryption module processes the parsed data again according to the custom protocol, and then sends the processed instruction or data to the communication module to control the communication module to perform the corresponding function. In this way, the application module and the communication module of the mobile terminal are completely isolated, and the application module cannot directly communicate with the communication module. In this way, not only the encryption requirements are met, but also high-speed communication can be processed. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0028] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present invention, and have no specific meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0029] It should be noted that the terms "first", "second" and the like in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0030] Figure 1 A mobile terminal provided for the present embodiment is used for communication and Internet access. The mobile terminal includes an application module, a communication module and an encryption module. The encryption module is connected between the application module and the communication module. The application module, the communication module and the encryption module are three independent modules. In the present embodiment, the application module, the communication module and the encryption module are physically independent. In other embodiments, the application module, the communication module and the encryption module are logically independent. The application module can send control instructions or data to each other with the encryption module, and the communication module can send control instructions or data to each other with the encryption module. The application module and the communication module cannot directly transmit control instructions or data, and need to be processed by the encryption module. The encryption module receives control instructions or data from the application module or the communication module, and after parsing the control instructions or data, determines to execute the corresponding instructions according to the parsing results or transmits the parsing results to the communication module or the application module after further processing.

[0031] In this way, the application module and the communication module of the mobile terminal are completely isolated, and the application module cannot directly exchange data with the communication module. In this way, not only the encryption requirements are met, but also high-speed communication can be handled.

[0032] The application module is used to perform initial control instruction transmission or initial data transmission with the encryption module according to a custom protocol.

[0033] In this embodiment, the application module can be an application processor, and the application processor generates corresponding instructions according to the application program installed on the operating system of the mobile terminal. The initial control instruction or initial data refers to the instruction or data from the instruction generating end or the data generating end. The custom protocol refers to a set of customized protocols for encrypting control instructions or data, thereby replacing traditional control instructions or data. It should be noted that the custom protocol is applied to the application module, encryption module and communication module of the mobile terminal, that is, when each module sends control instructions or data to other modules, it will package the information according to the custom protocol to form encrypted control instructions or data.

[0034] In an optional embodiment, if Figure 2 As shown, the custom protocol includes length, protocol header, type field, status field, command field, data field and check field, among which the type field is used to define the instructions or data transmission mode between the application module, communication module and encryption module; the status field is used to define the status of the application module, communication module and encryption module, and the command field is used to define instructions of different functions. Check field: used to check the integrity of the packet

[0069] Through the above-mentioned custom protocol, when each module sends information, it can be packaged into corresponding control instructions or data according to the custom protocol, so that the module that receives the control instruction or data can parse it according to the custom protocol. In this way, the purpose of completely isolating the application module and the communication module through the encryption module is achieved.

[0070] In an optional embodiment, if Figure 3 As shown, the application module and the encryption module transmit instructions through a control channel, and the application module and the encryption module transmit data through a data channel. In this embodiment, the application module is used to transmit initial control instructions to the encryption module through the control channel. The control channel is used to control key negotiation, key management, data encryption and decryption and other processes.

[0071] The encryption module is used to receive and parse the initial control instruction or initial data, generate a target control instruction or target data from the parsed initial control instruction or initial data according to the custom protocol, and send the target control instruction or target data to the communication module.

[0072] Specifically, in this embodiment, the encryption module is used to receive and parse the initial control instruction to perform the corresponding function. The encryption module pre-configures the content in the custom protocol, so that when the encryption module receives the initial control instruction or initial data sent by the application module, the initial control instruction or initial data can be parsed according to the custom protocol. After parsing, the specific control content or data content of the initial control instruction can be obtained. For example, the specific control instruction can be an instruction to control the encryption module to perform a corresponding function, such as changing a password, and the specific control instruction can also be an instruction to control the communication module to perform a corresponding function, such as turning on the 5G data function.

[0073] In an optional embodiment, in this embodiment, the encryption module and the communication module transmit instructions through the control channel, and the encryption module and the communication module transmit data through the data channel. The encryption module is also used to, when receiving and parsing the initial control instruction as a control instruction sent to the communication module, generate a target control instruction according to the custom protocol from the instruction data obtained by parsing the initial control instruction, and transmit the target control instruction to the communication module through the control channel. Specifically, in order to isolate the application module and the communication module, by setting the encryption module in the middle of the data transmission process between the application module and the communication module, the encryption module needs to parse the control instruction or data sent by any module according to the custom protocol first, and then determine whether it needs to be re-packaged according to the custom protocol and sent to another module based on the result of the parsing.

[0074] The communication module is used to receive and analyze the target control instruction or target data, and perform corresponding operations.

[0075] Specifically, the communication module is a 5G communication module. The communication module is also pre-configured with the content of the custom protocol. The communication module receives the target control instruction or target data through the control channel, and parses the target control instruction or data according to the custom protocol to obtain specific control content or data. In this embodiment, a control channel is included between the communication module and the encryption module, and the communication module receives the target control instruction transmitted by the encryption module through the control control.

[0076] Furthermore, the encryption module is also used to negotiate keys with the application module and the communication module respectively to establish an encryption channel, and the encryption channel is used to transmit data. The encryption channel refers to the data channel mentioned above. Specifically, when the encryption module executes the corresponding function according to the control instruction received through the control channel or when the encryption module receives the status information fed back by the communication module, if it is determined that data transmission is required, the control module negotiates keys with the application module and the communication module respectively to establish an encryption channel. It should be noted that the encryption module can establish an encrypted data channel only with the application module or only with the communication module according to the specific situation, or establish an encrypted channel between the application module and the communication module.

[0077] In an optional embodiment, the encryption module is further used to re-negotiate keys with the application module and the communication module respectively to establish an encryption channel when a change in the IP address is detected or at every preset time interval.

[0078] Through the above implementation, the application module, encryption module and communication module are completely isolated, and different contents are transmitted through different transmission channels, namely, control channel and data channel. Since the data channel uses Gigabit Ethernet port, it can handle high-speed communication. At the same time, the control channel is used to control key negotiation, key management, data encryption and decryption and other processes. In this way, the data encryption requirements in the case of 5G high-speed network data transmission are realized.

[0079] Below, according to the attached Figure 4 This article gives examples to illustrate the process of each module processing through custom protocols.

[0080] The application module packages the instruction data according to the custom protocol to generate a control command, and sends the control command to the encryption module through the control channel. The encryption module parses the control instruction according to the custom protocol to determine its control content. The control content includes reporting the status to the application module, sending it to the communication module, and the encryption module processing the instruction. In this example, the control content is sent to the communication module. Therefore, the encryption module repackages the parsed content according to the custom protocol to send it to the communication module through the control channel. The communication module parses the control instruction according to the custom protocol and performs corresponding operations according to the parsed content, for example, reporting the status to the encryption module or processing the command. It should be noted that the content that can be parsed by each module is pre-defined by the custom protocol, and the specific content is as shown in the custom protocol content above.

[0081] Furthermore, in order to improve the security of the mobile terminal, Figure 5 As shown, when the mobile terminal is turned on, the application module is also used to determine whether the encryption module is detected when the mobile terminal is detected to be turned on. When the encryption module is not detected, the control is shut down; when the encryption module is detected, the control is turned on.

[0082] Specifically, when the mobile terminal is turned on, the encryption module is detected by the application module to ensure that the encryption module is in a normal working state or a standby state. If the encryption module is not detected, the system determines that the mobile terminal is in an unsafe state at this time, and therefore controls the shutdown so that the current operator cannot use the mobile terminal. In an optional embodiment, when the encryption module is not detected, a prompt message is displayed on the screen, such as "no valid encryption module is detected". If the encryption module is detected, the power is controlled to be turned on.

[0083] Furthermore, in order to further improve the security of the mobile terminal, Figure 6 As shown, the application module is also used to perform verification when the encryption module is detected, and control shutdown when the verification fails; and control startup when the verification passes.

[0084] Specifically, since the current user is still an illegal user after the mobile terminal detects the encryption module, that is, not the owner of the mobile terminal, in order to prevent the illegal user from deciphering the screen decryption password of the mobile terminal through software after the mobile terminal is turned on, the application further verifies the encryption module after detecting the encryption module and before the power-on is completed. In this embodiment, the verification includes password verification, and when the password verification fails, the control is shut down. In an optional embodiment, when the password verification fails, the control is shut down, and at the same time, the encryption module is deregistered to face the illegal user to crack the password. In other embodiments, the verification also includes authentication, and when the authentication is successful, the control is turned on, and when the authentication is unsuccessful, the control is shut down.

[0085] Through the mobile terminal provided by the present application, an encryption module is added between the application module and the communication module of the traditional mobile terminal, and the control instruction or data generated by the control application module according to the custom protocol is not a conventional control instruction or data, and then the control instruction or data generated according to the custom protocol is sent to the encryption module, and the received control instruction or data is parsed by the encryption module. If the parsing determines that the control instruction or data is sent to the communication module, the encryption module processes the parsed data again according to the custom protocol, and then sends the processed instruction or data to the communication module to control the communication module to perform the corresponding function. In this way, the application module and the communication module of the mobile terminal are completely isolated, and the application module cannot directly communicate with the communication module. In this way, not only the encryption requirements are met, but also high-speed communication can be handled.

[0086] It should be noted that the computer program content that may be involved in the scheme recorded in the above specific implementation method is the prior art and is not an improvement of this application. This application improves the connection relationship between the modules in the circuit so that the modules can cooperate with each other when working, recover the heat energy lost by the equipment, and convert it into electrochemical energy stored in the power module. On the one hand, the heat dissipation effect of the equipment is enhanced through thermoelectric materials to achieve the effect of cooling and extending the battery life. On the other hand, the energy utilization rate of the power module is improved to extend the battery life of the equipment.
