Big data security protection cloud system based on trusted calculation

Abstract

The invention discloses a big data security protection cloud system based on trusted calculation. The big data security protection cloud system constructs a security configuration system based on a trusted security grading system and minimal trees on the basis of systems having security grading functions and trusted security configuration functions, and provides a trusted calculating environment for the security protection of information through the cooperation with a security network monitoring system. The trusted protection cloud system starts from the acquisition and security grading of basic data, divides the network nodes into four different security grades by calculating the importance values of the network nodes, and constructs an integral trusted environment, and by means of the security grading configuration with high credibility, the trusted security of information security and protection is guaranteed, the data cannot be acquired randomly, and a good balance between the calculated quantity and trusted security configuration is achieved.

Description

technical field [0001] The invention relates to the field of big data, in particular to a big data security protection cloud system based on trusted computing. Background technique [0002] Cloud computing has attracted more and more users, especially enterprise users. Through cloud computing, enterprise users do not need to build and maintain their own data centers, but only need to quickly apply for and release cloud service providers according to their own business load requirements. The various resources provided have successfully liberated major enterprise users from the huge cost consumption of infrastructure construction and maintenance, allowing them to focus more on the development of their core business. Cloud computing has such powerful advantages, but due to its unique features such as virtualization technology, data hosting and outsourcing services, it also faces unprecedented security challenges. First of all, security problems in traditional networks, such as...

Problems solved by technology

First of all, security problems in traditional networks, such as denial of service attacks and distributed denial of service attacks, are increasing in the cloud platform. At the same time, the characteristics of multi-tenant sharing of cloud computing also breed some new security risks, such as side channel attacks; Although there have been many studies on cloud security in industry and academia, the research on cloud internal network protection is still in its infancy.
