Access control method and system in cloud computing system

Abstract

The invention provides an access control method and system in a cloud computing system. The method comprises: receiving an access request of the could computing system from a user, wherein the access request comprises identify information of the user; according to the identify information of the user, determining the role of the user in the could computing system, and according to the role of the user, checking the operation authority of the roll in the could computing system; according to the identity information of the user, determining resources accessible to the user in the could computing system; according to the operation authority of the roll of the user and the resources accessible to the user, obtaining an authorization certificate, wherein the authorization certificate records the user's operation authority over the accessible resources; and after obtaining the access request of the user, according to the authorization certificate of the user, controlling the access request of the user.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to a method and system for access control in a cloud computing system. Background technique [0002] With the rise of cloud computing, the computer field is undergoing profound changes. my country's cloud computing service market is in its infancy, and cloud computing technology and equipment already have a certain foundation for development. The overall scale of my country's cloud computing service market is small, but the momentum of catching up is obvious. According to Gartner estimates, in 2011, my country accounted for less than 3% of the global cloud computing service market of about 90 billion US dollars, but the annual growth rate reached 40%. It is expected that the gap between my country and foreign countries in cloud computing will gradually narrow in the future. [0003] To sum up, cloud computing has the following characteristics: [0004] (1) Ultra-large scale: ...

AI Technical Summary

Problems solved by technology

In 2009, the cloud computing services of companies such as Google, Microsoft, and Amazon experienced major failures, which affected the information services of thousands of customers and further aggravated the industry's concerns about the security of cloud computing applications.

[0013] The development of cloud computing provides powerful redundant storage and fault-tolerant mechanisms, as well as more reliable data physical storage security, but there is a sufficiently secure solution in terms of access control. The security issues mentioned above are also access caused by control security
