Asymmetric Authentication as a Service in Private Cloud, Formal Validation by Scyther

Abstract

Cloud computing is beneficial instoring and operating from anywhere along with many other benefits to society. Cloud computing benefits can be taken in Public Cloud, Private Cloud or Hybrid Cloud. It can be accessed in mainly three services namely Platform as a service, Infrastructure as a service and Software as a service. To enhance its reach as per the user requirements anything as a service model is there, in which as per user’s required service is provided. Authentication plays a vital role in access management to cloud data. Private cloud is the most secured cloud as it is mainly used by Organizations to provide data to their Employees. Employee Authentication in an organization for the employees is also done by employees. To make authentication process more secure this paper proposes Authentication as a Service in Private cloud. The proposed Protocol is validated by Formal system tool Scyther which shows Proposed protocol is robust in nature.
