Interest in cloud computing market is growing rapidly in the recent years. It provides on-demand, high scalability computing resources with high availability and reliability. However, security is considered as one of the biggest obstacles for cloud computing. In this paper, we focus on the main security and privacy issues, pertinent to store and share data on untrusted cloud storage. We have investigated several existing approaches focused on security concerns in cloud computing. We classify the discussed studies based on three categories, which are: encryption and key management approaches, searching methods over encrypted data and access control schemes. We provide a comparative study of the existing solutions from each category identifying their strengths and limitations. We emphasize that although several techniques were proposed to protect data from cloud provider or any unauthorized users, there are still limitations need to be tackled. Therefore, we identified the research challenges indicating the future research directions in this area.
