Secure scheme on mobile multi cloud computing based on homomorphic encryption

Mobile technologies have become increasingly essential in our life as they offer great possibilities of uses, to users. Mobile cloud computing is a new paradigm that allows users to fully utilize mobile technologies exceeding the resources calculation limit. This exponential use of cloud services through mobile devices has allowed users to download, to share and retrieve their personal data anywhere and anytime. This increase in mobile traffic and circulation of personal data of users through internet has caused many security problems and sparked the interest of the attackers. We propose in this paper a light and strong authentication mechanism based on homomorphic encryption, to secure access for mobile users to the remote multi cloud servers. It also provide an implementation and simulation of our mechanism to demonstrate its robustness and reliability, and give a proof of concept of the authentication, integrity and confidentiality.
