摘要：Cloud computing has changed the IT industry ever since it evolved. Cloud computing is basically cost effective and on demand service offered to the clients. The resources in the cloud are rented according to the needs and budget of the client. As the cloud has involvement of many parties and resources its security remains a major issue. Cloud Computing is still not able to reach its true potential due to limitations in security offered in the cloud. In the present scenario, there is dependency on more than one cloud i.e. organizations use services from multiple clouds. This leads to a multi-cloud or cloud-of-clouds environment. Security in such a multi cloud environment is an even more complex issue to deal with as authentication and authorization of more than one cloud are required at once. Cloud is synonymous with the Internet. So the first step in dealing with the cloud security is the use of usernames and passwords. Even passwords get hacked and can prove to be unsafe if used over a long time. One Time Passwords are better way of using user name-password based authentication. In this paper we discuss the use the one time password implementation for authenticating services from multiple clouds at once. This paper elaborates what actually the cloud is. It then elaborates about the use of multi-clouds in organizations. It then investigates the security issues in cloud and finally the one time password co ncep t. The implementation of this model is then discussed.
