Enhanced security for cloud storage using linear block cipher algorithm

Cloud Computing is an emerging paradigm which has become today’s hottest research area due to its ability to reduce the costs associated with computing. Cloud computing, it is most interesting and enticing technology which is offering the services to its users on demand over the internet. Since Cloud Computing stores the data and disseminated resources in the open environment, security has become the main obstacle which is hampering the deployment of Cloud environments. Even though the Cloud Computing is promising and efficient, there are many challenges for data security as there is no vicinity of the data for the Cloud user. The main scope of this paper to solve the security issues in both cloud providers and cloud consumers using existing hill cipher symmetric key algorithm with some implementation on modulo function.
