MULTI FACTOR MODEL FOR AUTHENTICATION IN SECURITY OF CLOUDS

Abstract

In this dissertation, we present a layered framework for cloud security. Cloud computing is a new way to deliver services over the internet. Cloud computing architecture gives a proper management to share and distribute all available resources and services over the whole world via computer network. Authentication is a key factor for security, which is a mechanism to establish connection that authenticates the person‟s identity. Traditional authentication approaches are not good enough to provide strong information security in modern cyber-attacks.A number of well-known protocols for authentication are considered the next-generation mobile and computer network services. The potential weaknesses of current existing protocols can be solved by categorization of services and authentication levels in terms of their significance and confidentiality. This can offers mutual and also two-factor authentication that is considered more secure against various phishing attempts than existing authentication protocol. We propose a new level wise authentication imposing several factors for cloud computing. This proposed framework provides efficient and feasible mechanism which can be easily integrated into existing password authentication techniques. This proposed framework is verified by cloud server which authenticates user data. We are using several factors like arithmetic expression, one time password and magic number.
