Improving security and energy-efficiency for cloud-based storage platforms in mobile computing environments

Abstract

With the development of mobile computing, massive storage platform is playing a critical role for building innovative mobile applications. However, most of the current mobile storage systems can only provide simple storage service with certain degree of security guarantee, and ignore the distinctive characteristics and requirements of mobile users. In this paper, we present a lightweight mobile storage platform, which is constructed by cloud storage technology and several innovative mechanisms are incorporated for providing better file query experience, enhanced data security, and optimised energy-efficiency. Extensive experiments are conducted to evaluate the prototype implementation, and the results indicate that it is effective to obtain better tradeoffs between QoS performance and energy consumption.
