Problems solved by technology

Problems caused by this mechanism: 1) The system may reject the user's normal request for a long time due to the user's early misoperation; 2) For non-sensitive services, this approach also greatly affects the service continuity of the system and availability, resulting in reduced revenue for cloud service providers

Embodiment Construction

[0040] The present invention is based on dynamic game theory and cloud service classification user belief correction method, such as figure 1 shown, including the following steps:

[0041] (1) Establish the payment matrix of cloud service providers and trusted users, cloud service providers and untrusted users respectively, based on which establish incomplete information of cloud service providers and trusted users, cloud service providers and untrusted users Dynamic game model.

[0042] The payment matrix between the cloud service provider and the trusted user is: the trusted user sends a normal service request, and the corresponding matrix payment values ​​of the cloud service provider accepting the service request, not responding to the service request, and rejecting the service request are: ((1- α )( U n - C n ), (1- α )( S n - Q n )), (- αq i C n , - αq i ( S n + Q n )), (- α (1- q i )( C n + P a ), - α (1- q i )( S n + Q n ));

Abstract

The invention relates to a user belief revision method based on a dynamic game theory and cloud service classification. The method comprises the following steps: (1) establishing payment matrixes of a cloud service provider and a credible user as well as the cloud service provider and an incredible user respectively, and establishing incomplete information dynamic game models of the cloud service provider and the credible user as well as the cloud service provider and the incredible user; (2) classifying cloud services into sensitive services and non-sensitive services, and performing belief revision respectively in order to monitor user behaviors; (3) computing the current belief values of the users in combination with the history behavior sequences of the users in order to give different response strategies. By adopting the method, the balance of the cloud services between continuity and safety is facilitated.

Description

technical field [0001] The invention relates to the technical field of cloud services, in particular to a user belief correction method based on dynamic game theory and cloud service classification. Background technique [0002] In recent years, cloud computing, as a new industrial model, has led a new business revolution and at the same time has aroused a research boom of global researchers. However, the existing cloud system architecture makes the cloud service system have a huge number of users, especially the diversity of user behaviors, which will cause the system to face more threats that are difficult to prevent; if too harsh security policies are adopted, user services may be interrupted. Therefore, the high availability and fault tolerance mechanism of the system are also important aspects of security. Therefore, cloud service providers must improve their services from the following aspects: availability management, access control management, and access monitoring;...
