Securing Data in Mobile Cloud Computing using Dual Encryption Techniques

The use of mobile devices is increasing day by day as it is handy, provides higher level of mobility, and allows us to perform tasks which were only possible in the computer once. With increased jobs also comes huge amount of data which cannot be maintained on mobile due to its size and security concerns. Moreover we want the data to be available globally and can be accessed on any media through internet. Here falls in the concept of cloud. A cloud storage system, consisting of a collection of storage servers, provides long term storage services over the Internet. The emergence of cloud computing has changed the world upside down, after which mobile cloud computing was emerged as a potential technology. But there still exist few threats like security, reliability, heterogeneity and privacy which prevent the consumers from adopting mobile cloud computing. In today’s world n number of cloud service providers are available in market and they play a very important role in improving trust and security among the clients which can be used as a storage provider. When the service providers are used for both cryptographic operations and storage then there is a huge threat of unauthorized access or usage of data. We propose a trusted third party approach using dual encryption in order to increase security among the cloud service providers.
