With the development of cloud computing and
mobility, mobile cloud computing has emerged and become a
focus of research. By the means of on-demand self-service and
extendibility, it can offer the infrastructure, platform, and
software services in a cloud to mobile users through the mobile
network. Security and privacy are the key issues for mobile
cloud computing applications, and still face some enormous
challenges. In order to facilitate this emerging domain, we
firstly in brief review the advantages and system model of
mobile cloud computing, and then pay attention to the security
and privacy in the mobile cloud computing. By deeply
analyzing the security and privacy issues from three aspects:
mobile terminal, mobile network and cloud, we give the
current security and privacy approaches.
