Embodiment 1

[0028] figure 1 It shows the flow of the data transmission method for intranet and intranet Internet provided by the embodiment of the present invention, and only shows the part related to the embodiment of the present invention for the convenience of description.

[0029] Such as figure 1 As shown, the intranet and intranet data transmission method provided in this step includes the following steps:

[0030] Step S1. Obtain the field names of the fields in the data tables that need to be synchronized to the intranet from the Internet structured database, and each piece of data has a corresponding encrypted value under each field name.

[0031] Structured data refers to data that is logically expressed and realized by a two-dimensional table structure, strictly follows the data format and length specifications, and is mainly stored and managed through a relational database. A relational database refers to a database that uses a relational model to organize data. It stores da...

Embodiment 2

[0047] figure 2 The structure of the intranet and Internet data transmission device provided by the embodiment of the present invention is shown, and only the parts related to the embodiment of the present invention are shown for convenience of description.

[0048] Such as figure 2 As shown, the internal and external network Internet data transmission device provided in this embodiment includes:

[0049] The database value acquisition unit 1 is used to obtain the field name of each field in the data table that needs to be synchronized to the intranet in the Internet structured database, and there is a corresponding encrypted value under each field name of each piece of data;

[0050] The string composition unit 2 is used to combine all field names and corresponding encrypted values ​​according to shuffling rules for each piece of data to be transmitted to obtain combined data. Each piece of combined data is separated by a delimiter, and multiple pieces of combination The ...

Abstract

The invention is suitable for the technical field of internet security, and provides an intranet and extranet internet data transmission method and device, and the method comprises the steps: specifying a field name needing to be synchronized, encrypting a field value through an encryption algorithm to obtain an encryption value, carrying out the mixed arrangement of the field name and the encryption value, and packaging the field name and the encryption value into a data character string through processing; storing the data character string into a temporary file, copying the data character string into a specified address, restoring the data character string in an intranet through reverse analysis to obtain original format data, and finally adding the original format data into an intranetdata table. Through field value encryption and mixed arrangement, the security of data transmission is improved, the data is converted into the temporary file and then copied to the specified addressof the intranet security boundary access platform, and the data in the address can only be read by the intranet security boundary access platform, so that the security of the data is further ensured.

Description

technical field [0001] The invention belongs to the technical field of Internet security, and in particular relates to an Internet data transmission method and device for internal and external networks. Background technique [0002] As informatization brings people various material and cultural enjoyments, we are also facing increasingly serious security threats from the Internet, such as network data thieves, hacker attacks, virus publishers, and even leakers inside the system. . Although we are widely using various complex software technologies, such as firewalls, proxy servers, intrusion detectors, and channel control mechanisms, hacker activities are becoming more and more rampant in both developed countries and developing countries, and they are pervasive. caused serious harm to society. At the same time, what is even more disturbing is that the number of hacker websites on the Internet is still increasing, making it easy to learn hacking techniques and obtain hacking...
