[0013] This application solves the problem of how to efficiently and securely perform key exchange and digital certificate transmission between the starting device and the terminal device in the existing technology by providing an end-to-end encrypted communication method and electronic equipment in wireless communication construction. It achieves the goal of end-to-end encrypted secure communication, and achieves the technical effect of ensuring the security of communication data during transmission and preventing unauthorized access and data leakage.

[0014] Below, the technical solutions in the present application will be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments of the present application. It should be understood that the present application is not limited to the example embodiments described herein. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application. It should also be noted that, for the convenience of description, only the parts related to the present application are shown in the accompanying drawings, rather than all of them.

[0015] For example, please refer to the attached Figure 1 The present application provides an end-to-end encrypted communication method in wireless communication construction, wherein the method specifically comprises the following steps: Step S100: Acquire a starting-end device in wireless communication construction, and generate a predetermined key through the starting-end device.

[0016] Specifically, firstly, the starting end device in the wireless communication construction is obtained. Then, a predetermined key is generated through the starting end device. In this way, the starting end device has the basis for secure communication, which provides a basic guarantee for communication security in the wireless communication construction.

[0017] Step S200: Obtain a predetermined digital certificate, transmit a predetermined public key in the predetermined key to a terminal device in the wireless communication construction based on the predetermined digital certificate, and determine through the terminal device whether the predetermined digital certificate complies with the effective transmission constraints.

[0018] Specifically, first obtain a predetermined digital certificate. Next, based on the digital certificate, transmit the public key in the predetermined key to the terminal device in the wireless communication construction. Then, the validity of the digital certificate is judged by the terminal device to determine whether it meets the effective transmission constraints. This ensures the security of communication and prevents unauthorized access and data leakage. By obtaining and verifying the digital certificate and transmitting the public key to the terminal device, security is provided for wireless communication. This helps to ensure the confidentiality and integrity of communication and improves the reliability of communication.

[0019] Step S300: If the predetermined digital certificate meets the effective transmission constraint, an encrypted communication instruction is issued.

[0020] Step S400: Based on the encryption communication instruction, the target communication data is encrypted on the starting end device using a predetermined private key in the predetermined key to obtain target encrypted communication data, and the target encrypted communication data is transmitted to the terminal device.

[0021] Specifically, first check whether the predetermined digital certificate meets the effective transmission constraint. If so, issue an encrypted communication instruction. Next, based on this instruction, the initiating device uses the private key in the predetermined key to encrypt the target communication data and generate the target encrypted communication data. Then, the encrypted data is transmitted to the terminal device. In this way, the communication data is protected during the entire transmission process to prevent unauthorized access and data leakage. By verifying the validity of the digital certificate, issuing an encrypted communication instruction, and encrypting and transmitting the communication data on the initiating device, secure data transmission in wireless communication is successfully achieved.

[0022] Step S500: At the terminal device, the target encrypted communication data is decrypted using the predetermined public key.

[0023] Specifically, at the terminal device, the target encrypted communication data is decrypted using a predetermined public key. In this way, the communication data originally encrypted during the transmission process can be restored to its original state for use by the receiving party. By using a predetermined public key to decrypt the encrypted communication data at the terminal device, the security of the data during the transmission process is ensured. This helps prevent unauthorized access and data leakage, and improves the reliability of communication.

[0024] Further, step S100 of the present application includes: An initial value is generated based on the principle of a chaotic mapping algorithm, wherein the initial value is sensitively dependent on initial conditions; a pseudo-random number sequence is generated based on the initial value, and the predetermined key is constructed according to the pseudo-random number sequence; wherein the predetermined key is constructed according to the pseudo-random number sequence, including: randomly extracting a first pseudo-random number from the pseudo-random number sequence, and using the first pseudo-random number as the predetermined private key; randomly extracting a second pseudo-random number from the pseudo-random number sequence, and binding the second pseudo-random number with the starting device identifier of the starting end device to obtain the predetermined public key; and binding and encapsulating the predetermined private key and the predetermined public key to obtain the predetermined key.

[0025] Specifically, a chaotic mapping algorithm is used to generate a secure predetermined key. That is, firstly, an initial value is generated, a pseudo-random number sequence is constructed, and these pseudo-random numbers are used to generate a predetermined private key and a public key, and finally the two are bound and encapsulated to form a predetermined key.

[0026] Specifically, first, an initial value is generated based on the principle of the chaotic mapping algorithm. Since the chaotic system is sensitively dependent on the initial conditions, even a small change in the initial value will lead to completely different outputs, thereby increasing the security of the system. Next, a pseudo-random number sequence is generated based on this initial value. Then, the first pseudo-random number is randomly extracted from this pseudo-random number sequence as the predetermined private key, and then the second pseudo-random number is randomly extracted and bound to the identifier of the starting device to form a predetermined public key. Finally, the predetermined private key is bound and encapsulated with the predetermined public key to obtain the predetermined key. In this way, the generation process of the predetermined key not only ensures randomness, but also ensures a secure association with a specific device.

[0027] The initial value and pseudo-random number sequence generated by the chaotic mapping algorithm successfully constructed the predetermined key. This not only improves the security of key generation, but also ensures the unique binding of the key to a specific device, thereby enhancing the security of the entire communication system.

[0028] Furthermore, the present application also includes: After randomly extracting a second pseudo-random number from the pseudo-random number sequence and binding the second pseudo-random number to the starting device identifier of the starting end device to obtain the predetermined public key, the method also includes digitally signing the predetermined public key to obtain a predetermined signature public key, wherein the predetermined signature public key is used to replace the predetermined public key, and is bound and encapsulated with the predetermined private key to obtain the predetermined secret key.

[0029] Specifically, the security of the predetermined public key is enhanced by digital signature processing. After randomly extracting the second pseudo-random number in the pseudo-random number sequence and binding it with the identification of the starting end device, the predetermined public key is further digitally signed to generate a predetermined signature public key. That is to say, first, after randomly extracting the second pseudo-random number in the pseudo-random number sequence, it is bound to the identification of the starting end device to form a predetermined public key. Next, the predetermined public key is digitally signed. Digital signature is an encryption technology that ensures the integrity of the public key and the verification of the source. The predetermined signature public key is obtained through this step. This predetermined signature public key then replaces the original predetermined public key, and is bound and encapsulated with the predetermined private key to finally form a predetermined key. In this way, the predetermined key not only has randomness and device specificity, but also increases the security of the digital signature.

[0030] The security of the key is further enhanced by performing digital signature processing after the predetermined public key is generated. The use of the predetermined signature public key ensures the integrity and reliability of the public key during transmission and application.

[0031] Further, step S300 of the present application includes: Based on the starting device identification, digital signature and certificate validity period, the predetermined digital certificate is formed; when the starting device identification, digital signature and certificate validity period in the predetermined digital certificate all meet the valid transmission constraints, the encrypted communication instruction is issued.

[0032] Specifically, a secure predetermined digital certificate is constructed through the starting device identification, digital signature and certificate validity period, and an encrypted communication instruction is issued under the condition of meeting the effective transmission constraints to ensure the security of communication. Specifically, first, a predetermined digital certificate is formed based on the starting device identification, digital signature and certificate validity period. This digital certificate contains key information for verifying the identity of the starting device and ensuring the integrity of the public key. Next, it is checked whether the starting device identification, digital signature and certificate validity period in the predetermined digital certificate all meet the effective transmission constraints. These constraints may include the legitimacy of the device, the validity of the digital signature, and whether the certificate is within the validity period. If all these conditions are met, an encrypted communication instruction will be issued. In this way, encrypted communication will only be carried out after the identities of the communicating parties and the validity of the certificate are ensured, thereby improving the security of communication. By constructing and verifying the predetermined digital certificate and issuing an encrypted communication instruction under the condition of meeting the effective transmission constraints, secure data transmission in wireless communication is successfully achieved.

[0033] Further, step S400 of the present application includes: Acquire a temporary session key, and use the predetermined private key to asymmetrically encrypt the temporary session key to obtain an encrypted session key; symmetrically encrypt the target communication data based on the temporary session key and the predetermined private key to obtain the target encrypted communication data; mark the encrypted session key to the target encrypted communication data, and transmit it to the terminal device.

[0034] Specifically, the communication data is encrypted using a temporary session key and a predetermined private key to ensure the security of the communication. This mainly includes obtaining a temporary session key, asymmetrically encrypting the temporary session key using a predetermined private key, and symmetrically encrypting the target communication data using these keys, and finally transmitting the encrypted session key and the target encrypted communication data to the terminal device.

[0035] Specifically, first obtain a temporary session key. This key is used to symmetrically encrypt communication data, which increases the flexibility and security of communication. Next, use a predetermined private key to asymmetrically encrypt the temporary session key to obtain an encrypted session key. In this way, even if the encrypted session key is intercepted during transmission, it cannot be decrypted without a predetermined public key, ensuring the security of the session key. Then, based on the temporary session key and the predetermined private key, the target communication data is symmetrically encrypted to obtain the target encrypted communication data. Symmetric encryption algorithms are highly efficient and suitable for encrypting large amounts of data. Finally, the encrypted session key is marked to the target encrypted communication data and transmitted to the terminal device. In this way, the terminal device can use the predetermined public key to decrypt the encrypted session key, and then use the decrypted session key to decrypt the target communication data.

[0036] By obtaining temporary session keys, asymmetrically encrypting them with predetermined private keys, and symmetrically encrypting target communication data using these keys, secure data transmission in wireless communications is successfully achieved.

[0037] Furthermore, the present application specifically includes: The target communication data is sliced ​​to obtain a target slicing result, wherein the target slicing result includes multiple slice data segments; a first slice data segment among the multiple slice data segments is encrypted based on the temporary session key and the predetermined private key to obtain a first encrypted data segment; and a set of encrypted data segments formed based on the first encrypted data segment is compressed to obtain the target encrypted communication data.

[0038] Specifically, the security and transmission efficiency of communication data are enhanced through slicing and encryption processing. It mainly includes slicing the target communication data, encrypting the slice data segment using a temporary session key and a predetermined private key, and compressing the encrypted data segment set to finally form the target encrypted communication data. Specifically, first, the target communication data is sliced ​​to obtain a target slicing result including multiple slice data segments. Slicing processing can improve the flexibility and efficiency of data processing. Next, based on the temporary session key and the predetermined private key, the first slice data segment of the multiple slice data segments is encrypted to obtain a first encrypted data segment. In this way, each slice data segment is individually encrypted and protected. Then, the encrypted data segment set formed based on the first encrypted data segment is compressed to obtain the target encrypted communication data. Compression processing can reduce the size of the data, improve the transmission efficiency, and maintain the integrity of the data. By slicing and encrypting the target communication data, and compressing the encrypted data segment set, secure and efficient data transmission in wireless communication is successfully achieved.

[0039] Further, step S500 of the present application includes: The terminal device asymmetrically decrypts the encrypted session key on the target encrypted communication data based on the predetermined public key to obtain the temporary session key; uses the temporary session key to symmetrically decrypt the target encrypted communication data to obtain target decrypted data; and sequentially adjusts and reorganizes multiple decrypted data segments in the target decrypted data to obtain the target communication data.

[0040] Specifically, first, the terminal device uses a predetermined public key to asymmetrically decrypt the encrypted session key on the target encrypted communication data to obtain a temporary session key. This step is safe because only the corresponding private key can decrypt the data encrypted by the public key. Next, the target encrypted communication data is symmetrically decrypted using this temporary session key to obtain the target decrypted data. Symmetric decryption is efficient and suitable for rapid decryption of large amounts of data. Finally, multiple decrypted data segments in the target decrypted data are sequentially adjusted and reorganized to obtain the target communication data. This step ensures the integrity of the data so that the recipient can correctly understand and use the communication data. By using a predetermined public key to decrypt the encrypted session key on the terminal device, then using the temporary session key to decrypt the target communication data, and reorganizing the decrypted data segments, secure data reception and decryption in wireless communication is successfully achieved. Ensure that the terminal device can safely and accurately receive and decrypt the communication data from the initiating device.

[0041] In summary, the end-to-end encrypted communication method in wireless communication construction provided by this application has the following technical effects: By acquiring the starting-end device in the wireless communication construction, and generating a predetermined key through the starting-end device; acquiring a predetermined digital certificate, transmitting the predetermined public key in the predetermined key to the terminal device in the wireless communication construction based on the predetermined digital certificate, and judging whether the predetermined digital certificate meets the effective transmission constraint through the terminal device; if the predetermined digital certificate meets the effective transmission constraint, issuing an encryption communication instruction; based on the encryption communication instruction, encrypting the target communication data using the predetermined private key in the predetermined key on the starting-end device to obtain the target encrypted communication data, and transmitting the target encrypted communication data to the terminal device; at the terminal device, decrypting the target encrypted communication data using the predetermined public key. That is to say, firstly, ensuring the communication security in the wireless communication construction, specifically including acquiring the starting-end device and generating the predetermined key, then acquiring the digital certificate, and judging whether the certificate meets the effective transmission constraint through the terminal device. Next, if the digital certificate meets the effective transmission constraint, an encryption communication instruction will be issued, and then based on this instruction, the starting-end device uses the predetermined private key to encrypt the target communication data, and transmits the encrypted data to the terminal device. Finally, at the terminal device, the encrypted communication data is decrypted using the predetermined public key.
