Mobile Cloud computing applications are the new extensions of cloud technologies. Nowadays, these clouds technologies have rapid growth in IT Industry.using cloud, mobile devices can store and retrieve any kind of data from cloud networks. Despite the many benefits of these technologies, there are some issues such as security and privacy that degrade the efficiency of mobile cloud computing. In the first part, we discussed data sharing in mobile cloud computing. In the second part, we discussed the detailed literature review of various algorithms and methodologies. The purpose of the review is considering the problems and limitations of previous research gaps in terms of secure optimal data sharing with limited resources security paradigms such as using public key cryptographic systems

AES algorithm, DES algorithm, Proxy-Re-encryption
