Secure cloud computing system

Abstract

The invention is applicable to the field of information security, and provides a secure cloud computing system. The secure cloud computing system comprises a cloud center, a secure cloud computing server and a proxy terminal, the cloud center is connected with the secure cloud computing server, the proxy terminal is installed on the secure cloud computing server and is in communication connection with the cloud center; a data storage form of three structures, namely, an independent database, an isolated database and a shared database, is adopted, the storage form can be selected according to the data security level, thereby not only saving resources and reducing the cost, but also providing effective security guarantee for the data storage; meanwhile, by means of the identity verification manner, the condition of user information leakage caused by the weak protection measure of the cloud computing terminal is effectively solved, the identity loss, data stealing, information loss and other potential safety hazards are prevented, and in the case of communication abnormality or network interruption, local terminal backup area data and local terminal backup area data and parameters can be used to prevent the loss of user data information in extreme cases.

Description

technical field [0001] The invention belongs to the field of information security, in particular to a secure cloud computing system. Background technique [0002] Cloud computing is a new type of computing model that can more effectively use computing resources to provide users with various data services. It links a large number of computing resources, storage resources and software resources, and uses virtual technology to provide users with customizable Computing, storage and application services, avoiding the construction and maintenance of users' own heavy infrastructure. However, the centrally managed cloud computing center will become a key target of hacker attacks. Due to its unprecedented openness and complexity, its security is facing more severe tests than ever before. The access control of big data resources in cloud computing is the key to cloud computing security. At the core of the problem, access control is an important means to realize the confidentiality of...
