Maha Jebalia, Asma Ben Letaïfa, Mohamed Hamdi, Sami Tabbane · 2014
Cloud computing is a revolutionary model that allows companies and individuals to outsource their data to external data centers which become responsible for their storage and processing. Nevertheless, this new computing model has raised some issues related to data security. In fact, since cloud computing environments are shared between different users, there is definitely a way that a malicious (undesirable) cloud user will find to access and alter other users' data. Ponemon Institute research report [1] has showed that data security has become of great concern to the users who aren't likely to entrust their data to an external company without a guarantee. In fact, cloud users are still unenthusiastic about storing their data in an external data centers and think that storage cloud systems are vulnerable. In this context, several proposals have been presented in the literature to provide secure cloud storage.
