Achieving energy efficiency and security in mobile Cloud computing

Abstract

Computation offloading to the Cloud for energy efficiency in portable devices is an emerging area of research triggered by the widespread use and acceptance of smart phones. A number of architectures have already been proposed in this context. However, security issues in the cloud still remain a concern that can play an important role in deciding whether offloading really helps to achieve energy efficiency in mobile phones. Our framework is based on a layered data approach together with user selected security policies. This motivated us to develop a mathematical model to depict the energy consumption when performing a security-enhanced computation in the cloud. The model demonstrates the potential energy saving in the event of user or organization specified policy for secure computing and data storage in the Cloud.
