BER Performance of DES-Convolution with code rate ½ over LMS and AWGN Channels. The figure 12, demonstrates the analysis of conventional crypto-coding with code rate ½ and crypto-coding. Over land mobile satellite channel the BER performance is upto 10 -3 for single iteration. as number of iterations increases the performance.

With the development of cloud computing and mobility, mobile cloud computing has emerged and become a focus of research. Mobile Cloud Computing (MCC) integrates mobile computing and cloud computing aiming to extend mobile devices capabilities. 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. There is huge market for mobile based e-Commerce applications across the globe. Security and privacy are the key issues for mobile cloud computing applications. The limited processing power and memory of a mobile device dependent on inherently unreliable wireless channel for communication and battery for power leaves little scope for a reliable security layer. Thus there is a need for a lightweight secure framework that provides security with minimum communication and processing overhead on mobile devices. The security and privacy protection services can be achieved with the help of secure mobile-cloud application services.

Mobile Cloud Computing (MCC) is a combination of three main parts; they are mobile device, cloud computing and mobile internet. With the help of MCC, a mobile user gets a rich application delivered over the Internet and powered by cloud-backed infrastructure. The importance of Cloud Computing is increasing and it is receiving a growing attention in the scientific and industrial communities. Now a day's the major concern for mobile user is security and protection in mobile cloud computing. MCC refers to the availability of cloud computing services in a mobile environment. There are number of loopholes and challenges exist in the security policies of MCC. This paper present a review of MCC, its security & privacy issues and vulnerabilities affecting cloud computing systems, analysed and compared various possible approaches proposed by the researchers to address security and privacy issues in MCC.
