While the embodiments of the present application provide an embodiment of an encrypted communication method, it should be noted that, although a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different from that shown or described herein.
The encryption communication method comprises the following steps:
step S10, the first terminal establishes a communication connection with the second terminal based on a fifth-generation mobile communication technology, and sends a key request to the second terminal, where the second terminal sends feedback information corresponding to the key request to the first terminal after receiving the key request;
the first terminal is a key requester, specifically a vehicle, a mobile terminal, an infrastructure capable of communication, etc., and the second terminal is a key sender, specifically a vehicle, a mobile terminal, an infrastructure capable of communication, etc. In the present embodiment, the first terminal is exemplified by the vehicle a, and the second terminal is exemplified by the vehicle B.
In the present embodiment, the vehicle a and the vehicle B establish a communication connection based on a fifth-generation mobile communication technology. It can be understood that, in the prior art, a key generation server needs to be constructed after the different terminals establish connections, that is, when determining that communication data between the vehicle a and the vehicle B needs to be encrypted, the process is that the vehicle a sends a key request to the server, the server generates a key according to the key request, and sends the generated key to the vehicle a and the vehicle B, so that the vehicle a and the vehicle B encrypt the communication data according to the key acquired from the server.
It can be understood that, in the present application, the first terminal and the second terminal are installed with an application program for encryption and decryption, when a user uses the first terminal to perform data communication, the application program for communication of the first terminal is started, whether the user starts encrypted communication is determined, and if the user selects to perform encrypted communication, a key request is generated by the application program.
The key request is request information for acquiring a key sent by the first terminal. The format of the key request may be a http (hypertext Transfer protocol) request, a ftp (file Transfer protocol) request, or a format conforming to other feasible text Transfer formats, and the present invention is not limited thereto. More specifically, the key request may be embodied as a message, which may consist of a request line, a message header and a message body, for example, for a key request in http format. After the second terminal receives the key request, the second terminal knows that the first terminal requests to obtain the key according to the message body in the key request, generates corresponding feedback information containing the key, and sends the feedback information to the first terminal.
Similarly, the format of the feedback information generated by the second terminal may be a http (hypertext Transfer protocol) request, a ftp (file Transfer protocol) request, or a format conforming to other feasible text Transfer formats, and the present invention is not limited thereto. The feedback information comprises a response line, a response head and a response body, wherein the first terminal obtains the secret key in the response body after receiving the feedback information of the second terminal.
Step S20, receiving the feedback information, and obtaining a key according to the feedback information;
and after receiving the feedback information, the second terminal sends the feedback information to the application program. The application gets the key from the responder.
Before the step of receiving the feedback information and obtaining the key according to the feedback information, the method includes:
a step S01 of, when the feedback information is not received, executing a step of sending a key request to the second terminal;
step S02, calculating the number of times of sending the key request;
and step 03, when the number of times is greater than the preset number of times, performing plaintext communication, wherein the plaintext communication is to encrypt the communication data.
In this embodiment, after the first terminal sends the key request to the second terminal, the timer is started to start timing, and when the counted time is greater than the preset time (20s), the sending of the key request instruction to the second terminal is executed again, the number of times of sending the key request instruction to the second terminal is counted, and when the counted time is greater than the preset number of times (3 times), it is determined that plaintext communication is performed with the second terminal. The preset time and the preset times can be changed according to the requirement of the user on the communication quality. In this embodiment, when the number of times that the first terminal sends the key request to the second terminal is greater than the preset number of times, the plaintext communication between the first terminal and the second terminal is controlled, that is, the encryption operation is not performed on the communication data between the first terminal and the second terminal, so that the problem that the first terminal frequently sends the key request to the second terminal when the second terminal cannot perform encrypted communication is avoided, and the communication quality is reduced.
Step S30, encrypting the communication data according to the secret key, and sending the encrypted communication data to the second terminal.
The communication data is data generated by the first terminal and the second terminal in the communication process and comprises data transmitted by a file or communication data generated during communication. In the present application, a description is given of call data generated when a first terminal and a second terminal make a call by using communication data as an example.
Specifically, the present embodiment can be exemplified as follows. When detecting that the user initiates a call with the vehicle B by operating an application installed in the vehicle A, and when determining that the user selects to establish encrypted communication with the vehicle B, sending a request for obtaining the secret key to the vehicle B. After the vehicle B receives the key request, prompt information of 'the vehicle B requests for encrypted communication' is displayed on a terminal interface, and when confirmation information that a user selects 'enter encrypted communication' is received, an application program in the vehicle B is controlled to generate a key for encrypted communication with the vehicle B, and the key is packaged to generate feedback information and is sent to the vehicle A. After the vehicle a receives the key, the call data to be sent to the vehicle B is encrypted by the key, and the call data acquired in the vehicle B is decrypted.
After the step of encrypting the communication data according to the key and sending the encrypted communication data to the second terminal, the method further includes:
step S40, after the communication data is sent, sending an instruction to delete the key to the second terminal.
After the first terminal and the second terminal complete communication, the first terminal sends an instruction for deleting the secret key, and meanwhile, an application program in the first terminal also executes operation for deleting the secret key used in the transmission process, so that the secret key is prevented from being leaked.
With the rapid development of artificial intelligence technology, the realization of intelligent and automated driving of vehicles has become the key point of the development of the automobile industry, and V2X (vehicle to electric) technology is the basis for realizing automatic driving of vehicles. Especially, the service data interaction between the terminals can improve the driving safety, reduce the congestion and the vehicle energy consumption, improve the traffic efficiency and the like. In the prior art, the key for encrypted communication is generally obtained by the key generation server, but when the server is attacked, the security of communication data between terminals is definitely affected. In this embodiment, the first terminal establishes a connection with the second terminal based on a fifth generation mobile communication technology, and sends a key request to the second terminal after receiving an instruction that encrypted communication needs to be performed with the second terminal, so that the second terminal generates feedback information including a key according to the key request and sends the feedback information to the first terminal when receiving the key request of the first terminal. When the second terminal acquires the request instruction of the first terminal, the second terminal directly generates feedback information corresponding to the request instruction, wherein the feedback information comprises the secret key and is sent to the first terminal, and a server for generating the secret key is not required to generate and forward the secret key, so that the problem of secret key leakage caused by the fact that the server for generating the secret key is attacked is avoided, and the security of encrypted transmission between the first terminal and the second terminal is improved.
The steps that the first terminal establishes communication connection with a second terminal based on a fifth generation mobile communication technology and sends a secret key request to the second terminal include:
step S11, the first terminal sends broadcast information of the connection address of the second terminal, where the second terminal sends response information after receiving the broadcast information;
step S12, establishing connection with the second terminal according to the response information;
step S13, sending the key request to the second terminal based on the connection.
The connection address is an address for establishing connection with the second terminal. In this embodiment, the first terminal may send and obtain a connection address of the second terminal, and if the first terminal and the second terminal are in the same local area network, the second terminal directly establishes a connection with the first terminal; and if the first terminal and the second terminal are in different networks, the base station performs rebroadcasting. And after the second terminal receives the rebroadcast broadcast information, sending response information so that the first terminal establishes connection with the second terminal according to the response information and sends a key request to the second terminal after establishing the connection.
Before the step of sending the key request to the second terminal based on the connection, the method includes:
step S01, receiving the operation information of the user, and determining whether to carry out encrypted communication according to the operation information;
step S02, when it is determined that the encrypted communication is performed, performs a step of transmitting a key request to the second terminal based on the connection.
In this embodiment, after the first terminal and the second terminal establish a connection, the first terminal receives operation information of the user to determine whether the user selects to enter encrypted communication, and when the user selects to perform encrypted communication with the second terminal by installing an application program in the first terminal, the first terminal sends a key request for obtaining a key to the second terminal, so that the second terminal generates the key by the application program installed in the second terminal after receiving the key request. In this embodiment, after the specific information selected by the user is obtained, the second terminal sends the key request for obtaining the key, so that the key server for generating the key is not required to generate the key, and the security of the key is improved.
Further, referring to fig. 3, a further embodiment of the encryption communication method of the present application is provided.
The second embodiment of the encrypted communication method differs from the first embodiment of the encrypted communication method in that, after the step of encrypting the communication data according to the key and transmitting the encrypted communication data to the second terminal, the method further includes:
step S40, when receiving a request instruction for modifying the key, sending modification information to the second terminal, where the second terminal modifies the key after receiving the modification request, and sends the modified key to the first terminal;
in step S50, the first terminal encrypts the communication data based on the modified key.
It can be understood that, when encrypted transmission is performed between the first terminal and the second terminal, if all encrypted data are encrypted by using the uniform key, there is a risk of information leakage to all communication data in the communication process between the first terminal and the second terminal undoubtedly when the key is stolen. For this purpose, in the request, after the second terminal receives the key request of the first terminal, the second terminal adds the use time of the key to the feedback information sent by the second terminal according to the communication protocol. When the time for the first terminal to encrypt and decrypt by using the key is longer than the preset time, the key request for obtaining the key is sent to the second terminal again so as to change the key for encrypting communication between the first terminal and the second terminal, and the security of communication between the first terminal and the second terminal is enhanced.
Further, referring to fig. 4, another embodiment of the encrypted communication method of the present application is provided.
In this embodiment, the communication encryption method is applied to the second terminal, and includes:
step S100, the second terminal establishes communication connection with the first terminal based on a fifth generation mobile communication technology and receives a secret key request sent by the first terminal;
step S200, generating corresponding feedback information according to the secret key request, wherein the feedback information comprises the secret key;
step S300, sending the feedback information to the first terminal.
The second terminal establishes connection with the second terminal based on the fifth generation mobile communication technology, and receives a key request sent by the second terminal. Further, an application for realizing communication data transmission with the second terminal is installed, and a key is generated based on the received key request, and it is understood that the key generation method may generate a key based on a key generation algorithm in the application, and generate feedback information from the generated key and other information (the use time of the key, the address information of the first terminal, and the like) and transmit the feedback information to the first terminal. When the first terminal receives the secret key, the communication data is encrypted or decrypted according to the secret key, so that when the encrypted communication is carried out between the first terminal and the second terminal, the secret key can be directly generated at the second terminal without reconstructing a server for generating the secret key, and the security of the encrypted communication between the first terminal and the second terminal is improved.
The step of generating corresponding feedback information according to the key request includes:
step S210, randomly generating a secret key according to the secret key request;
step S220, packing the secret key to generate corresponding feedback information.
After receiving the request instruction of the first terminal, the second terminal randomly generates a key through an application program installed in the first terminal, packages information such as the randomly generated key and the survival time of the key to generate feedback information, and sends the feedback information to the first terminal. The mode of randomly generating the secret key is used, and the security of encrypted communication between the first terminal and the second terminal is improved.
After the step of sending the feedback information to the first terminal, the method further includes:
step S400, performing an encryption operation on the communication data sent to the first terminal according to the key in the feedback information, and performing a decryption operation on the communication data received from the first terminal.
In this embodiment, when receiving the key of the second terminal, the first terminal sends the confirmation information to the second terminal based on the received key, so that the second terminal confirms that the first terminal has received the key. After confirming the key received by the first terminal, when the second terminal sends the communication data to the first terminal, the encryption operation is executed on the communication data sent to the first terminal by using the key. At the same time, the received communication data from the first terminal is decrypted using the key. The second terminal encrypts the communication data sent to the first terminal, so that the communication safety between the first terminal and the second terminal is improved.
