Data Security of Mobile Cloud Computing on Cloud Server:

Abstract

Cloud Computing have a great impact to modern life. It change the way of our living. From the smart home to smart city, smart agriculture to smart healthcare, from smart governance to defence, they promise to make our surroundings more intelligent, easier and efficient. In spite of their usefulness, the challenges they face are the security issues. The data or the information that flows over the network are bidirectional. So, the most vital question that may arise is how far the communication is secured from unauthorized access. Therefore a robust security model is needed to make the device communication as well as data communication more secure. In this paper I show some security on data in mobile computing.

Cloud Computing :

Cloud computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. The term is generally used to describe data centers available to many users over the Internet.

Mobile cloud computing security:

Mobile Cloud Computing Security One of the key concerns of most cloud operators’ is securing the mobile computing user’s privacy and the data or application integrity. With both the mobile users and application developers benefiting from the large storage area the cloud, they must also be aware of the danger when dealing with data/application integrity, authentication, and digital rights. Mobile Cloud Computing is actually a combination of Cloud Computing and mobile networks, thus,issues relating to security can be divided into cloud security and mobile network user’s security,

1.1. Mobile Network User’s Security

There are many types of security vulnerabilities and threats to different mobile devices such as smart phones, PDAs, cellular phones, laptops, etc. Some applications can also cause security and privacy issues for mobile users (Dinh, et al., 2011). The four main problems concerning user or subscriber security are discussed below:

1.1.1.Security for mobile applications

One of the simplest ways to detect any security threats is to install and run security software or an antivirus programme on the mobile device. However, because mobile devices have limited processing capabilities and power, it could be difficult to protect these devices against threats.Several approaches have been developed to transfer the security and threat detections mechanisms such as authentication, token management, authorization, and data encryption to the clouds.

1.1.2.Privacy

Private information such as the user’s current location and other important data could

compromise a user’s, privacy. For example, the use of the global positioning system (GPS) for location based services (LBS). These threats to privacy can be minimised by selecting and analysing the nature of the applications, and what are the specific services that should be moved to the cloud. However, this gives rise to concerns that cloud providers or companies will use and the information or give this information to government agencies, etc., without the permission or knowledge of the users.

1.1.3.Data Ownership

Another issue relevant to Mobile Cloud Computing concerns ownership of the purchased digital media. With cloud computing, it is now possible to store media files such as audio, video, and e-books remotely. This raises the question of who actually owns these media. If a user bought the media through a certain service and the media is stored in a remote storage, there is the risk of losing access to the purchased media.

1.1.4.Data Access and Security

Issues relating to access and security are important to applications and programmes that rely on remote data storage and internet access to work. For example, the online calendar and contact applications are used by subscribers to store important dates and other user information, but should a power outage occur, then it would affect their daily function. Mobile Cloud Computing is vulnerable because it requires multiple points where access can be interrupted. High speed and strong signal reception can also adversely affect services to mobile devices users.

2.1. Securing Information on the Cloud

Both individuals and enterprises recognize the advantage of storing large amount of data and application on a cloud. As such, the issues of integrity, authentication, and digital rights must be addressed

2.2.1. Integrity :

Data integrity is one of the major concerns of mobile users when using the cloud. Several solutions have been proposed to address this issue (e.g. (Tanenbaum A & Van Steen M, 2007; W. Wang, Li, Owens, & Bhargava, 2009)). However, the energy consumption of mobile users has not been taken into consideration. Consideration for energy consumption was made in (Itani, Kayssi, & Chehab, 2010). There are three main components in this requirement: the mobile client, the cloud storage service, and a trusted third party. There are three phases in this scheme:
