Embodiment 1

[0043] Example 1: The following combination Figure 1 to 3 What is shown is only one of the embodiments of the present invention. In order to solve the above-mentioned problems, the present invention adopts the following technical solutions to achieve: a database adaptive encryption method, including the following steps:

[0044] S1: Record the requested content of the application's database;

[0045] To encrypt data, first obtain the data, obtain the database request content in the database, and analyze and encrypt the data based on the content.

[0046] Modern Web application systems have relatively fixed usage patterns for databases, and specific encryption methods can be selected according to the specific characteristics and usage of the data to avoid efficiency problems caused by encryption and achieve a better balance between confidentiality and availability.

[0047] S2: Analyze the usage of specific fields, scan the database mode, and obtain data characteristics;

[0048] Under...

Embodiment 2

[0064] Example 2: Still combined Figure 1 to 3 What is shown is only one of the embodiments of the present invention. In order to make a database adaptive encryption method of the present invention more accurate, the encryption process is more rigorous and more convenient, there are many data processing steps in the present invention:

[0065] First, before performing step S1, a storage library for storing the recorded database request content is established.

[0066] Due to the large communication traffic of the database service, the storage library here uses a caching mechanism. First, it is stored in the form of a file on the disk and recorded for a period of time so that the data in it contains all the patterns used by the application on the database. Make the coverage of data analysis more comprehensive.

[0067] Then, step S2 is specifically:

[0068] S21: Obtain database request data;

[0069] Here is to get the database request data from the repository.

[0070] S22: Read the ...

Abstract

The invention provides a database self-adaptive encryption method and relates to the technical field of database security. The database self-adaptive encryption method comprises the steps that S1, request content of a database of application programs is recorded; S2, use modes of specific fields are analyzed, database patterns are scanned, and data features are acquired; S3, semantic features of the fields in the database are determined; and S4, different encryption algorithms are selected according to the semantic features of the fields. Through the database self-adaptive encryption method, database field types can be effectively recognized, appropriate encryption algorithms are selected according to the field types to perform encryption, encryption is rigorous, the encryption process isconvenient, and the high efficiency of the database on data retrieval still can be maintained.

Description

Technical field [0001] The present invention relates to the technical field of database security, [0002] In particular, the present invention relates to a database adaptive encryption method. Background technique [0003] Data information resource sharing application is the basic principle of information construction. Each enterprise has its own enterprise system, which stores some information that can be disclosed. In addition, there is information sharing among some enterprises. With the in-depth development of informatization, the demand for the sharing and application of these information resources is increasing, but there is A certain number of business systems that share and use relevant information resources have weak information security assurance capabilities and serious security risks. If some data information is leaked and abused, it will directly have a bad social impact and directly threaten social stability and national security. [0004] With the increasing applic...
