Embodiment Construction

[0060] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0061] A method for calculating trust based on AIFS weight of the present invention comprises the following steps,

[0062] S1: Select a cloud service provider for interaction;

[0063] S2: The user requests a service level l from the cloud service provider according to the demand; wherein, the service level l of the cloud service provider includes n service indicators k i l , and expressed in the form of a set of service index vectors as Depending on the service level l, k i l The service index values ​​are also different;

[0064] S3: Using the AIFS weight calculation method to determine the weight of the service index vector in step S2;

[0065] S4: Cloud service provision provides cloud service to the request according to the requested service level l;

[0066] S5: The user evaluates the service according to the obtained cloud...

Abstract

The invention relates to a method for calculating trust based on AIFS weight. The method is characterized in that one cloud service provider is selected to carry out interaction; a user requests one service grade for the cloud service provider according to a demand, wherein the service grade of the cloud service provider includes n service indexes and a form of a group of service index vectors is used to express; then an AIFS weight calculating method is used to determine weight of the service index vectors; the cloud service provider provides a cloud service for the request according to the requested service grade; the user evaluates the service according to the acquired cloud service so as to acquire an actual measured value of the service index vectors; and then according to the determined weight of the service index vectors, an evaluation value of the user to the cloud service provider is calculated; and the evaluation of the user to the cloud service provided by the cloud service provider determines a credit grade of the cloud service provider, global cloud service provider reputation calculation is performed and a total reputation value of the cloud service provider is acquired. The invention provides a cloud service provider optimization selection method which can be used to objectively and credibly evaluate a cloud service provider service result by the user.

Description

technical field [0001] The invention relates to a method for calculating trust based on AIFS weight. Background technique [0002] Trust plays an important role in a commercial cloud environment. It is one of the biggest challenges facing cloud technology. Trust enables users to choose the best resources in a heterogeneous cloud infrastructure. Evaluating cloud service security before choosing cloud services is also a must. Therefore, Trust Model(TM) serves as a security strength assessment and grading service for cloud applications and services. It can be used as a baseline for establishing the security of cloud services, uncovering deficiencies and improving cloud infrastructure. Literature [1] found that security issues are inseparable from trust issues. The trust model TM is an effective method. In recent years, more and more scholars have paid attention to and proposed methods to be applied to the field of cloud computing security. Cloud Service Provider (Cloud Ser...
