Data transmitting method and system applied to cloud system

Abstract

The invention discloses a data transmitting method and system applied to a cloud system. The method comprises the steps of receiving an identity authentication request transmitted by a user at a user side through dynamic data generating equipment; authenticating the identity of the user according to the identity authentication request; issuing an access license for the user who passes the identity authentication, and confirming a communication secret key in the data transmission process, wherein the access license has an expiry date; and dynamically authenticating the identity of the user if the access license of the user is within the expiry date during transmitting the enciphered data to the user, and stopping the data transmission when the authentication is failed. In the scheme, during the data transmission, the identity of the user is continuously authenticated by the user current status information obtained by the dynamic data generating equipment, and the encryption measures are cooperatively performed, so that the security of the data transmission in the process of interaction between a cloud side server and the user is improved.

Description

A data transmission method and system applied to a cloud system technical field The invention relates to the technical field of information security, in particular to a data transmission method and system applied to a cloud system. Background technique Cloud computing is based on open standards and services, centered on the Internet, and provides safe, fast, and convenient data storage and network computing services. It makes the "cloud" of the Internet a data center and computing center for every Internet user. In the cloud computing system, the processing and storage of massive data is located in the cloud server. When a user who logs in to the cloud server needs a service, he only needs to transmit the required service to the cloud server, and the cloud server will analyze and process the received service request, and finally return the corresponding result to the user. Even complex calculations or large-scale data query tasks can be quickly completed by cloud servers....
