MOBILE CLOUDS COMPUTING: CURRENT STATE, ARCHITECTURE AND PROBLEMSThe

SECURITY AND PRIVACY ISSUES IN MOBILE CLOUD COMPUTINGThis article investigates security and privacy issues on cloud platforms used in mobile cloud computing. Threats arisen from users' data protection and network security in mobile cloud computing are analyzed. At the same time, the article analyzes information security in mobile cloud computing, confidentiality, location and displacement of data, completeness of data, cyber attacks. Scientific-theoretical problems of security and privacy issues of mobile cloud computing are investigated and the status of researches in this direction is analyzed. IntroductionAt present, intensive research is being carried out to effectively utilize the computing and memory resources of data processing centers with the use of Cloud Computing technology throughout the world. The systems with large computing and memory resources are built based on computer networks with high-speed connection channel. The emergence of new cloud services and the development of mobile applications for mobile devices has recently led to the creation of mobile computing systems based on these technologies. At present, mobile users are widely benefitting from Cloud Computing technologies. The rapid growth of mobile devices (laptops, tablets, smartphones, etc.) in the world and their integration to cloud computing over the Internet through appropriate telecommunication technologies (GPS, 3G, 4G, Wi-Fi, etc.) has led to the development of a new technology -mobile cloud computing. Obviously, the capabilities of any mobile device (computing and memory resources) are limited. Nevertheless, mobile users use these devices to solve issues requiring great computing and memory resources. In this regard, cloud computing technologies are widely used. Thus, the problem of restricted computing and memory resources available on mobile devices can be eliminated with the use of cloud technologies. In recent years, the fall in prices of cloud services has enabled mobile users to benefit from these services.Storage and use of large-scale data of users and organizations in cloud attracts hackers and create privacy problems for mobile users [1,2]. In this regard, the threats to the security of mobile devices and the risks of mobile cloud computing have been studied and recommendations have been given. The main goal of a mobile computing environment is to provide mobile users with software applications and services through cloud service providers over the Internet. Thus, to ensure the access of users of mobile cloud computing to the applications on cloud servers, it is important to analyze problems occurring in different parts of the network, that is in mobile devices, network, mobile applications and their security.This article thoroughly explores the problem of data security and confidentiality of personal data emerged from the use of mobile cloud computing.

The term e-health is generally used to refer to the application of information technology in the delivery of different types of healthcare services. The use of technology in healthcare not only makes life easier for people, but also raises a number security issues. The article discuses and providers solutions for the security of smart devices and patient information stored in cloud services. Also considered were the methods of further enhancing the security of the electronic health system. Besides, the architecture and safety standards of smart hospitals have been researched.
