Cloud computing data security label management method and system

Abstract

The invention provides a cloud computing data security label management method and system, and relates to the field of cloud computing and data security. The method comprises the steps of setting a format of a cloud data security label, generating a new cloud data security label, storing the new cloud data security label in a client database and a server database; and loading client label data containing the new cloud data security label to a memory when a client is started, updating the label data in the operation process of the client in real time, and moreover, updating the server label data of the new cloud data security label to the server database. According to the method and the system, the format composition of the cloud data security label is defined; a label data type involved in the application and management of the cloud computing data security label is analyzed; a distributed storage scheme is provided; three response modes are designed for carrying out efficient processing on establishment, search, modification and deletion operations of the label data, and the influence on performance efficiency of the client is reduced.

Description

technical field [0001] The invention relates to the field of cloud computing and data security, in particular to a cloud computing data security label management method and system. Background technique [0002] Cloud computing represents an important trend in the development of scale, specialization and intensification in the IT field. The security of cloud computing has received more and more attention, and has become an important factor restricting the development of cloud computing technology and industry. Cloud computing security faces many challenges. Among them, data security is due to its basic position in practical applications. , has become the primary problem that needs to be broken through and solved most urgently. [0003] The root of cloud computing data security problems lies in the separation of data ownership and control rights. The service model of cloud computing is that users hand over data to cloud service providers for storage or entrust them to run cer...

Problems solved by technology

[0003] The root of cloud computing data security problems lies in the separation of data ownership and control rights. The service model of cloud computing is that users hand over data to cloud service providers for storage or entrust them to run certain applications, and users lose control over their data. In this service mode, malicious cloud services can directly steal users' private data without being discovered by users; untrustworthy components in the cloud platform, hackers, Trojan horses and other malicious software can illegally read, leak or tamper with users' sensitive data; Malicious behaviors such as virtual machine escape will lead to unauthorized use of user data between virtual machines. Due to the lack of strong security control technology support, users cannot ensure that their data is used correctly in the cloud platform
