An Efficient Two Factor Authentication Scheme Providing Secure Communication in Mobile Cloud Computing

Abstract

Integration of mobile networks with cloud computing platform led to development of mobile cloud computing. Since the communication between mobile devices and the cloud computing occur over wireless medium, securing the network becomes paramount. With the thorough literature survey, we found that many two factor authentication schemes proposed so far to preserve user anonymity are vulnerable to various security attacks, they also had shortcomes to achieve security goals. To overcome the issues related to the two factor authentication schemes in mobile cloud computing, a new scheme is proposed. Furthermore, we have simulated the proposed scheme using widely accepted AVISPA (Automated Validation of Internet Security Protocols and Applications) tool. With the simulated result of the proposed scheme, we show that the proposed scheme is secure against active and passive security attacks. Additionally, the proposed scheme is compared with Gope and Hwang's scheme and other related schemes in terms of computational cost and communication overhead. The proposed scheme is efficient, robust and suitable for practical implementation
