Survey on Mobile Cloud Computing
The cloud heralds a new era of computing where application services are provided through the Internet. Cloud computing can enhance the computing capability of mobile systems, but is it the ultimate solution for extending such systems' battery lifetimes. Cloud computing promises to democratize parallel data processing by making large server farms available to organizations that lack such resources in-house. Cloud computing promises a more cost effective enabling technology to outsource storage and computations. Existing approaches for secure outsourcing of data and arbitrary computations are either based on a single tamper-proof hardware, or based on recently proposed fully homomorphic encryption. The hardware based solutions are not scalable, and fully homomorphism encryption is currently only of theoretical interest and very inefficient.
