Novel signature verification process

Cloud computing is a model to access computing resources from anywhere. Cloud provides companies the opportunity to store their large amount of sensitive and confidential data on three different platforms-SaaS, PaaS, and IaaS. Among these three models of Cloud, SaaS has more security threats. So how is SaaS architecture improved to withstand security threats? In this paper, we present the vulnerabilities of SaaS architecture for security attacks and address the authentication attack among them. In our study, we analyze that every attack is possible only when the attacker overcomes the obligations of authentication and once he gains the access then everything is in his hands. So, in this paper we discuss about authentication attack with detailed information. Also, we find weakness of SaaS architecture. To overcome this weakness, we proposed novel process for signature verification architecture to improve the SaaS signature verification process by closing the vulnerability for authentication attacks. We design a new algorithm to prove our proposed plan and implemented using C language. With this, we are overcoming the authentication attack by closing the wrapping attack, which improves the efficiency of the SaaS model.
