Problems solved by technology

[0005] (1) Decreased access efficiency
Since the data is encrypted and stored, the user needs to decrypt the plaintext information when accessing the data, which reduces the efficiency of user access
[0006] (2) Key loss will result in unavailable data
[0007] To sum up, in the database system, usability and confidentiality have become mutually checks and balances and contradictions. How to coordinate the relationship between the two to achieve a flexible and reasonable balance in the application has become an important issue. However, in the existing In technology, there is no technical solution to this problem

Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of the present invention is not limited in any way.

[0029] In one embodiment of the present invention, construct as attached figure 1 The database cluster encryption system shown includes: a user application (10), a cluster controller (11), a plaintext node (13), an encryption component (12) and a ciphertext node (14). Wherein, the plaintext and ciphertext forms of the table testtab used for testing are respectively stored in the plaintext node (13) and the ciphertext node (14). Moreover, the administrator sets the cluster encryption system to work in a high security mode.

[0030] When the user application (10) initiates a write operation, for example, executes the following SQL command:

[0031] SQL=insert into table testtab values('test')

[0032] After receiving the request, the cluster controller connects to the ...

Abstract

The invention discloses a database cluster encrypting method and a database cluster encrypting system employing the method. The database cluster encrypting system comprises: one or more user applications, a cluster controller, one or more plaintext nodes, one or more ciphertext nodes and one or more encryption assemblies attached to the ciphertext node(s) and corresponding to the ciphertext node(s) one to one. The invention also discloses the database cluster encrypting method applied to the database cluster encrypting system. The method and the system provided in the invention solve major problems of a ciphertext database system in application and provide a more flexible technical implementation proposal for wider application of the database encryption technology, so that the security of the database system is improved.

Description

technical field [0001] The invention relates to a database cluster system, in particular to a database cluster encryption method and a database cluster encryption system using the method. It belongs to the field of information technology. Background technique [0002] With the continuous advancement of informatization, information assets have become one of the core assets of enterprises. How to use technical means to maintain the confidentiality and availability of enterprise business data has become a common concern of enterprises. As the core component of data storage and management, the confidentiality and availability of database systems have attracted widespread attention. [0003] Cluster technology is one of the important technical means to enhance the usability of database system. A database cluster gathers a group of database servers together to provide services to users using a unified input and output interface to obtain higher availability, faster response spee...
