Abstract

The demands for computing resource allocation, user management, and various contents management are increasing with the proliferation of cloud computing. A cloud service system has to provide the system services that are combined or shared based on the web environment, unlike a single application in the past. It has also evolved to appropriately allocate and combine service resources according to the needs and needs of various users to provide a user-dependent web environment. There is an increasing need for software convergence services in the form of software. In response to these needs, a variety of customized services are provided to a user who promises an optional service environment. Those services can be used in combination according to a user's purpose and needs, instead of providing an environment in which a user purchases and uses software locally. In particular, because cloud computing provides the process that a user gain accessing authority to the system which has been granted a service access right for a certain period of time, and including a process of expire the corresponding right is completed, a various authority access control method is designed. In this paper, we define the roles of users who access cloud computing service, and manage user rights according to each role, provide and expire appropriate service resources according to user's privilege and session information. Moreover we analyzed the procedures for constructing an algorithm for service ripple effects according to the procedure of granting service resources to each user and accessing web services and constructing a new role.

Highlights

  • The demands for computing resource allocation, user management, and various contents management are increasing with the proliferation of cloud computing

  • We define the roles of users who access cloud computing service, manage user authorities according to each role, and provide and expire appropriate service resources according to user's privilege and session information

  • In the privilege control system according to the existing user role, the process of granting the appropriate role defined to the user and the authority and access control for the service according to the privilege granted to the user have been defined

Introduction

The demands for computing resource allocation, user management, and various contents management are increasing with the proliferation of cloud computing. There is an increasing need for software convergence services in the form of software In response to these needs, a variety of customized services are provided to a user who promises an optional service environment. We define the roles of users who access cloud computing service, manage user authorities according to each role, and provide and expire appropriate service resources according to user's privilege and session information. Analyze the service ripple effects according to the procedure of each user accessing cloud computing service, granting service resource, and expiring. We analyze the effect of each user on the other users and the influence of other users on the service according to the correlation between the authority to access the cloud computing service that defined by the web portal and the role of the user who allocated the corresponding authority. Each service includes a function to control or share resources to be provided to users
