Integrating OTP Authentication Service in OpenStack

Cloud Computing is being intended to deliver information technology services based on internet on demand. The benefits of cloud technology are incomparable which takes the information technology into a new dimension. Organizations already invested for their own infrastructure are likely to set up private clouds to reap the benefits of cloud computing technologies. Cloud services are thriving by the open source software OpenStack. In this paper, we aim to introduce the largest open-source cloud operating system OpenStack with a new authentication mechanism. This paper tries to address the challenge of finding legitimate users by introducing One Time Password (OTP) as an authentication mechanism in OpenStack. Replay attacks can be defeated by using One Time Password. The OTP mechanism provides an extra level of protection which makes it extremely difficult for any potential intruder to abuse the recorded password that was already used to log into cloud service. The integration of OTP mechanism into OpenStack allows users to protect their credentials from unauthorized access. Also One Time Password is used to grant access to legitimate users into the cloud environment and to prevent access to malicious users bot attacks.With secured cloud environment users can enjoy lot many benefits of private cloud service.
