Abstract

In order to promote mutual trust and win-win cooperation between the users and the providers, we propose a trust-game-based access control model for cloud service in the paper. First, we construct a trust evaluation model based on multiple factors, such as the direct trust, feedback trust, reward punishment, and trust risk and further propose a weight method by maximum discrete degree and information entropy theory; second, we combine trust evaluation with the payoff matrix for game analysis and calculate the mixed Nash equilibrium strategy for the users and service providers; third, we give the game control condition based on trust level prediction and payment matrix to encourage participants to make honest strategy. Experimental results show that our research has good effect in terms of acceptance probability, deception probability, accuracy of trust evaluation, and cooperation rate in the cloud service.

Highlights

Cloud computing is a very popular technology in the field of information technology and is highly valued by the government, academia, and industry [1, 2]
We propose a trust-gamebased access control model for cloud service, which is one of the types of dynamic models, each access is modeled as a game between the subjects and objects, and the result of the game services is used as the basis for authorization decision
Baranwal and Vidyarth [15] proposed a new license control framework based on game theory in the cloud computing, and the results showed that there were a dominant strategy and Nash equilibrium in pure strategy

Summary

Introduction

Cloud computing is a very popular technology in the field of information technology and is highly valued by the government, academia, and industry [1, 2]. Apple and Amazon have launched cloud computing services, which allow personals and organizations to use dynamic computing infrastructure based on needs. Convenient and fast services are the core advantages of cloud computing, but cloud computing services have a lot of security problems, which have attracted widespread attention in the industry [3]. It is necessary to choose a good solution for requirement of customer in terms of service quality and cost
