Abstract

The problems (lack of storage, system trouble, problem of power supply etc.) in a single cloud with increase the use of clouds are being raised. For these reasons, multi-clouds are needed. In multi-clouds, Cloud providers as different forms of systems with different authentication systems demand an authentication to a user. So users using multi-clouds have different authentication ID and Password for each cloud because they have to authenticate differently for each cloud. As a result, users are inconvenient to manage multiple of authentication IDs and Passwords and users’ authentication information exposed whenever they access to multi-clouds is in a poor security. Integrated user authentication is needed to ensure an authentication of user’s safety and convenience in multi-clouds. So this paper suggests the user focused integrated authentication methods in multi-clouds environment using an authentication ticket issued from Brokerage Authentication Center (BAC).
