Embodiment Construction

[0089] We use the login process of the mobile cloud application to illustrate the flow of the dynamic authentication solution of the present invention, but it is not limited to the login process. After logging in, we will still periodically upload location information to detect anomalies. Once an exception occurs, execute the verification process in the program flow.

[0090] Such as figure 1 As shown, the flow of the entire authentication scheme is as follows:

[0091] ① The user sends a service request to the nearest server through the client. This mode is applicable to any connection model of mobile cloud computing. At this point, since the user has not logged in, similar to the current application, the user needs to be authenticated. The client sends the account and password information (input by the user or bound to the application) together with the geographic location information to the authentication server.

[0092] ②After receiving the user request, the authentic...

Abstract

The invention discloses a dynamic authentication method of a client side suitable for a mobile cloud. The method comprises the following steps: 1) conducting cluster analysis of historical location information of a user; 2) sending a cloud service request / requests to an authentication server through the client side by the user; 3) confirming a cluster A to which the current location information of the client side corresponds by the authentication server, if the ratio of the number of data points in the cluster A to a sum is less than a threshold value t, deciding that the current location information is an outlier and conducting authentication, if the authentication is passed, recording the current location information in a misinformation point collection and responding to the request, otherwise, refusing the request, and recording the current location information in an outlier collection; 4) if the sum of the recorded misinformation point collection and the recorded outlier collection is greater than a threshold value L, marking and combining the sum to be used as a training data of classification to obtain a classification model; and 5) as for subsequent cloud service requests of the user, utilizing the classification model to conduct classification for outliers to respond to the cloud service request. The method improves the data security and account security of the user.

Description

technical field [0001] The invention relates to a client dynamic authentication method suitable for mobile cloud, which belongs to the security field of mobile cloud environment, and is mainly applied in the authentication process of mobile client accessing cloud service in the mobile cloud computing environment, so as to ensure the user's data security and account Safety. Background technique [0002] Mobile cloud computing is a product of the integration of mobile computing and cloud computing. It hopes to use cloud computing technology to store and process data on mobile devices, so as to alleviate the inherent limitations of mobile devices, so that mobile applications can provide users with a richer service experience at a lower cost. [0003] First of all, the concept of mobile cloud should be clarified. The so-called mobile cloud refers to the computing facilities where mobile devices and cloud computing facilities jointly complete computing tasks such as data storag...
