If they do not match, access is rejected.

[0058] Each data block is initialized to ensure that each data block is unique;

[0059] The initialized data block is restored according to the reversal rule to obtain the offset data block;

[0060] To restore the offset data block, the offset data block is shifted forward by k positions according to the rotation offset k, to obtain the data block before the offset.

[0061] The data block before the offset is processed by the SHA-256 secure hash algorithm to generate a new message authentication code (MAC). This new MAC is then compared with the original MAC. If they match, it means that the data has not been tampered with.

[0062] Reconnect all data blocks according to the segmentation rules to obtain the plaintext data of the original communication content.

[0065] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0066] like Figure 1 As shown, a wireless communication transmission system based on a 5G base station includes a management center, which is communicatively connected to an information receiving module, an information preprocessing module, an information processing module, and an information transmission module.

[0067] The information receiving module consists of several antenna arrays installed in the 5G base station and is used to receive and send communication information.

[0068] The antenna array includes several subarrays, and each subarray includes several antenna elements; each antenna array is configured with a corresponding communication information range; each subarray is configured with a corresponding frequency service range; the antenna elements are divided into idle state and occupied state, and each antenna element has a different transmission rate;

[0069] Each antenna array is assigned a first-level information identification code, each subarray in each antenna array is assigned a second-level information identification code, and each antenna element in each subarray is assigned a third-level information identification code, with each information identification code being unique.

[0070] The communication information includes an information type tag, the IP address of the information sender, the communication content, and the IP address of the information receiver; the information type tag includes a primary tag and a secondary tag, wherein communication information with a primary tag is ordinary communication information, and communication information with a secondary tag is special communication information; the communication content includes plaintext data, the amount of communication information, and the frequency of communication information.

[0071] After receiving communication information, the information receiving module selects the corresponding communication link to transmit the received communication information. The specific process includes:

[0072] The appropriate antenna array is selected by matching the size of the received communication information with the range of communication information set in the antenna array.

[0073] The corresponding subarray is selected by matching the frequency of the received communication information with the frequency service range set in the corresponding subarray of the antenna array.

[0074] Antenna units are selected based on their status. If the antenna unit status is idle, the maximum transmission rate corresponding to each antenna unit is obtained, the antenna unit corresponding to the maximum value is marked, and that antenna unit is selected. If all antenna units are occupied, they are queued and wait for an idle state to appear.

[0075] The process of constructing a communication link based on the selected antenna array, its subarrays, and the antenna elements within those subarrays, and obtaining the communication link quality check code PX, includes:

[0076] Obtain the first-level information identification code of the antenna array, the second-level information identification code of the sub-array in the antenna array, and the third-level information identification code of the antenna element in the sub-array in the corresponding communication link, all of which are binary codes;

[0077] Identifiers are set to be associated with the first-level information identification code, the second-level information identification code, and the third-level information identification code respectively;

[0078] Generate first-level and second-level separators based on the first-level information identification code, the second-level information identification code, and the third-level information identification code, respectively;

[0079] The first-level separator separates the first-level information identification code and the second-level information identification code. The second-level separator separates the second-level information identification code and the third-level information identification code to form the corresponding communication link quality inspection code PX.

[0080] The information preprocessing module processes the communication information uploaded by the information receiving module and the communication link quality check code PX. The specific processing steps include:

[0081] Generate a three-level separator based on the communication link quality check code PX;

[0082] The communication link quality check code PX and the communication information are combined using a three-level separator to form preprocessed communication information;

[0083] Regarding the communication link quality check code PX, it should be further explained that the communication link quality check code is used to verify whether the communication links matched by the sender and receiver are consistent.

[0084] The information processing module processes the preprocessed communication information uploaded by the information preprocessing module. The specific processing steps include:

[0085] Based on the information type label in the obtained preprocessed communication information, the corresponding encryption scheme is selected. It should be further explained that, in the specific implementation process, the encryption scheme includes a first-class encryption scheme and a second-class encryption scheme. When the information type label is a first-class label, a first-class encryption scheme is selected, and when the information type label is a second-class label, a second-class encryption scheme is selected.

[0086] The information processing module is used to encrypt the preprocessed communication information according to the selected encryption scheme. The specific encryption process includes:

[0087] When the information type tag is a level-one tag, a type of encryption scheme is adopted, and the specific encryption process includes:

[0088] Obtain preprocessed communication information;

[0089] The communication link quality check code PX and the communication information are separated by the three-level separator of the preprocessed communication information.

[0090] The communication link quality check code PX is encrypted using the AES symmetric encryption algorithm;

[0091] The encrypted communication link quality check code PX and the communication information are combined using a three-level separator to form pre-transmission communication information.

[0092] When the information type tag is a level 2 tag, a type 2 encryption scheme is adopted, and the specific encryption process includes:

[0093] The communication link quality check code PX is separated from the communication information based on the three-level separator in the preprocessed communication information, and the communication link quality check code PX is encrypted using the AES encryption algorithm.

[0094] To improve information security, plaintext data of communication content is divided into data blocks according to segmentation rules.

[0095] It should be further explained that the segmentation is performed in the order of appearance and with equal size.

[0096] Each data block is processed by the SHA-256 secure hash algorithm to generate a message authentication code (MAC). This can detect whether the information has been tampered with during the information transmission process, thereby improving the authenticity of the information.

[0097] Generate a corresponding and unique initialization vector v for each data block, and perform initialization operations on the data block to ensure that each data block is unique, thereby improving the uniqueness of information;

[0098] For each data block, a corresponding and unique rotation offset k is generated. The characters in each data block are shifted k positions to the right according to the rotation offset k. Characters that exceed the data block boundary are returned to the beginning to improve information security.

[0099] Each character of the offset data block is reversed according to the reverse key rule to form ciphertext information;

[0100] Regarding the aforementioned inversion key rule, it should be further explained that the inversion key reverses characters in increments of three characters. If the number of characters in the data block is a multiple of three characters, the inversion proceeds normally; if the number of characters in the data block is not a multiple of three characters, the remaining characters are not inverted.

[0101] The encrypted communication link check code PX, the corresponding initialization vector v, the message authentication code MAC group, and the ciphertext information are packaged into a data packet to form new communication information.

[0102] The encrypted communication link quality check code PX and the new communication information are combined using a three-level delimiter to form pre-transmission communication information, which is then sent to the information transmission module.

[0103] The information transmission module is used to transmit pre-transmission communication information and send the pre-transmission communication information to the information receiving module of the receiver.

[0104] The receiving module of the receiver processes the pre-transmission communication information uploaded by the information processing module. The specific processing steps include:

[0105] The encrypted communication link quality check code PX is separated by a three-level separator in the pre-transmitted communication information;

[0106] The AES decryption algorithm is used to decrypt the communication link quality check code PX;

[0107] After decrypting the communication link quality check code PX, it determines whether the communication information is encrypted and selects the corresponding decryption scheme.

[0108] It should be further explained that, in the specific implementation process, the decryption scheme includes a first-class decryption scheme and a second-class decryption scheme;

[0109] When the information type label is a level-one label, a decryption scheme is selected, and the specific decryption process includes:

[0110] The encrypted communication link quality check code PX is separated by a three-level separator in the pre-transmitted communication information;

[0111] The AES decryption algorithm is used to decrypt the communication link quality check code PX;

[0112] To decrypt the communication link quality check code PX, it is necessary to further explain that the decoded communication link quality check code PX is split according to the delimiter, the corresponding information identification code is found according to the identifier, and compared with the three sets of information identification codes in the communication link before transmission to ensure that the communication link before and after the uploaded pre-transmission communication information is consistent. If they do not match, access is rejected; if they match, the transmitted communication information is received.

[0113] When the information type tag is a level 2 tag, it proves that the pre-transmission communication information uses a type 2 encryption scheme. A type 2 decryption scheme is then selected, and the specific decryption process includes:

[0114] The encrypted communication link quality check code PX is separated by a three-level separator in the pre-transmitted communication information;

[0115] The AES decryption algorithm is used to decrypt the communication link quality check code PX;

[0116] The communication link quality check code PX is split according to the delimiter, the corresponding information identification code is found according to the identifier, and compared with the three sets of information identification codes in the communication link before transmission to ensure that the communication link before and after the uploaded pre-transmission communication information is consistent. If they do not match, access is rejected.

[0117] Each data block is initialized to ensure that each data block is unique;

[0118] The initialized data block is reversed again according to the reverse key rule to obtain the offset data block;

[0119] Regarding the reversal operation, it should be further explained that the characters are reversed according to the reversal key in three-character increments, and the reversal operation is also performed by restoring the original characters in three-character increments. If the number of characters in the data block is an integer multiple of three characters, the reversal operation is performed again; if the number of characters in the data block is not an integer multiple of three characters, the reversal operation is performed by reading three characters at a time, and the remaining characters are not reversed.

[0120] For example:

[0121] Set the string corresponding to the initialization data block to ABCDEFGHIJK;

[0122] When encrypting a data block, every three characters of the initial data block are reversed according to the reverse key rule, resulting in CBAFEDIHGJK;

[0123] When decrypting the data block, every three characters of the encrypted initial data block are reversed again according to the reverse key rule, resulting in ABCDEFGHIJK;

[0124] Based on the decrypted result, the data block can be reversed again to recover the unencrypted data block;

[0125] To restore the offset data block, the offset data block is shifted forward by k positions according to the rotation offset k to obtain the original data block;

[0126] The data block after the offset is recovered is processed by the SHA-256 secure hash algorithm to generate a new message authentication code (MAC). This new MAC is then compared with the original MAC. If they match, it means that the data has not been tampered with, and the original communication information is obtained.

[0127] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
