Description

Technical Field

[0001] The present invention relates to the technical field of data security transmission, and in particular to a computer data security transmission method. Background Art

[0002] Computer storage is a virtual space, and it involves many security issues during information transmission. The existence of these security issues has a very adverse impact on the security of computer information transmission. In serious cases, it may even cause devastating damage to the stored information, causing serious damage to the economic property and privacy security of enterprises or individuals.

[0003] Existing data transmission technologies usually rely on basic encryption technology, but these technologies often lack real-time monitoring and effective response to illegal access during data transmission, making it difficult to detect problems in a timely manner and take measures to remedy them. Therefore, a computer data security transmission method is needed. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a computer data security transmission method, which solves the problem of lack of real-time monitoring during data transmission and effective response to illegal access during data transmission.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A computer data secure transmission method comprises the following steps:

[0007] Step 1: Determine whether the data file to be transmitted needs to be classified. If it is determined to be not, no classification is performed. If it is determined to be yes, encryption classification is performed for the corresponding file type;

[0008] Step 2: Configure a secure transmission channel. Configure the corresponding file transmission channel and transmission path according to the data file type. The transmission channel is equipped with specialized encryption for the data type.

[0009] Step 3: Release the inspection unit to the transmission channel. The inspection unit conducts a rapid inspection in the transmission channel to detect illegal access encountered during the transmission process and respond to the illegal access.

[0010] Step 4: During the data file transmission process, a check node is set to verify the integrity of the file. If the integrity is missing, it will be rejected. During the check node, the inspection unit is temporarily recovered to change the characteristics of the inspection unit;

[0011] Step 5: The data file is separated from the inspection node and the inspection unit is released again;

[0012] Step 6: After the data file arrives at the receiver, the sender sends the encryption classification key to classify and integrate the classified data;

[0013] Step 7: After data transmission is completed, disconnect the secure transmission channel and perform maintenance on the secure transmission channel.

[0014] Preferably, the specific steps of classifying the data files in step 1 include:

[0015] S1. Configure a quantitative function for the classified data in the same batch, and generate a classification number by the quantitative function;

[0016] S2. Assign numbers to the data files, insert random codes into the numbers, encrypt them, and take any extreme value of the inverse function of the quantitative function as the code.

[0017] Preferably, the inspection unit in step three only includes key bytes of the data file as priority retrieval individuals for illegal access, and when the inspection individual is retrieved, illegal access is triggered.

[0018] Preferably, the specific steps for responding to illegal access in step three are: performing data encryption, access interception, inducing data delivery and access countermeasures in sequence according to the progress of illegal access, and continuously issuing warnings to the sender and the receiver.

[0019] Preferably, the specific steps of verifying the integrity of the file in step 4 are:

[0020] S1. Retrieve the data file according to the key bytes carried by the inspection unit, and quickly verify the integrity of the key byte information;

[0021] S2. If the verification fails, a comprehensive verification is performed. If the missing rate is lower than the threshold, the message is rejected and resent. If the missing rate is higher than the threshold, the message is rejected and a warning is issued to the sender and receiver.

[0022] Preferably, the specific steps of changing the characteristics of the inspection unit in step 4 are: gradually increasing the number of inspection units and adjusting the inspection frequency of the inspection units.

[0023] Preferably, the encrypted classification key in step six is ​​an inverse function of the quantitative function of the classification key.

[0024] A computer data security transmission system, comprising:

[0025] A secure transmission channel establishment module is used to establish secure transmission channels that are specialized in different data information secure transmission protection capabilities;

[0026] Data classification module, used to classify and package data and perform classified encryption;

[0027] A data patrol unit sending module is used to output a patrol unit for patrol detection in a secure transmission channel to target illegal access and make an alarm for illegal access;

[0028] The illegal access countermeasure module is used to receive the alarms issued by the inspection unit and allocate response plans according to the progress of illegal access;

[0029] The data integration and decoding module is used to decode, integrate and restore the data after the receiving party receives the data file.

[0030] The present invention provides a computer data security transmission method, which has the following beneficial effects:

[0031] 1. The present invention significantly enhances the protection of data during transmission by encrypting classification and configuring specialized secure transmission channels, effectively preventing illegal access and data tampering, and ensuring information security. In addition, it also improves the monitoring capability of data integrity. Once integrity problems are found, they can be processed in a timely manner, thereby ensuring the reliability and security of data transmission.

[0032] 2. The present invention achieves rapid response and effective countermeasures to illegal access behavior by introducing inspection units and illegal access response mechanisms during the data transmission process. This method can not only detect and prevent illegal access in a timely manner, but also issue warnings to the sender and receiver when necessary, thereby enhancing the active defense capability of the entire transmission process and further ensuring the security and stability of data transmission.

[0045] S1. Retrieve the data file according to the key bytes carried by the inspection unit, and quickly verify the integrity of the key byte information;

[0046] S2. If verification fails, a comprehensive verification is performed. If the missing rate is lower than the threshold, the message is rejected and resent. If the missing rate is higher than the threshold, the message is rejected and a warning is issued to the sender and the receiver.

[0047] The specific steps of changing the characteristics of the inspection unit are: gradually increasing the number of inspection units and adjusting the inspection frequency of the inspection units.

[0048] Step 5: The data file is separated from the inspection node and the inspection unit is released again;

[0049] Step 6: After the data file arrives at the receiver, the sender sends the encryption classification key to classify and integrate the classified data. The encryption classification key is the inverse function of the quantitative function of the classification key.

[0050] Step 7: After data transmission is completed, disconnect the secure transmission channel and perform maintenance on the secure transmission channel.
