A Novel Strong Password Generator for Improving Cloud Authentication

Abstract

In recent years, there has been a growing interest in the cloud computing paradigm thanks to its benefits, such as multi-tenancy, scalability, cost efficiency and its unlimited storage. However, like any new technology, there are still a number of challenges relevant to this paradigm and most notably user authentication. In order to achieve better security than the alphanumerical password, this paper describes a scheme which allows strengthening the authentication process in the cloud environment using the password generator module by means of a combination of different techniques such as multi-factor authentication, One-time password and SHA1.
