Cloud computing secure access method, device and system

Abstract

The invention discloses a cloud computing secure access method, a device and a system. The method includes obtaining authentication information input by a client, determining a client identification of the client, which can not be changed voluntarily, when a common password corresponding to a user name is determined to be correct, determining whether a corresponding relationship between the client identification and the address of a cloud machine exists in a data base of a distribution authentication server or not through the distribution authentication server, determining whether a dynamic password is correct or not as well, if the corresponding relationship exists and the dynamic password is correct, informing the client of a successful logging, otherwise, informing the client of a failed logging, and when the password information corresponding to the user name is determined to be incorrect, informing the client of a failed logging. By means of the scheme, even though an illegal user steals the user name and the common password, the illegal user is incapable of establishing the corresponding relationship between the client identification and the address of the cloud machine, and the illegal user can not obtain a permission of logging in the cloud machine through stealing the common password, and thereby the safety of logging in the cloud machine is improved.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a cloud computing security access method, device and system. Background technique [0002] Cloud computing is an Internet-based computing method in which shared hardware and software resources and information are provided to computers and other devices on demand. The cloud platform provides services based on cloud computing. It is the supplier who provides the cloud platform, and the customer enjoys the service of the cloud platform provided by the supplier, so that the customer does not have to build his own company's infrastructure, and can completely rely on the cloud platform to create a new mirror instance . [0003] In specific cloud computing services, the provider's infrastructure can conveniently provide users with cloud machines. Users can use remote connection tools to connect to cloud machines, just like using a real physical machine. When t...

[0005] Although the existing cloud machine login method has a certain security effect, if the user name and password of the client are leaked, or the user name and password are stolen during the transmission process, then the illegal user can have the authority to log in to the cloud machine, so the existing The method of logging into the cloud machine is less secure
