Cloud computing is one of the emerging technology which is showing continuous advancement in the field of networking. Cloud computing is defined by National Institute of Standards and Technology (NIST)[1] as a model for enabling ubiquitous, on demand network access to a shared pool of configuration computing resources (e.g. computer networks, servers, storage, applications and services) ,which can be rapidly provisioned and release with minimal management effort. It is gaining popularity in all the areas. But still by far cloud computing sharing is behind one expected because of the security concerns (unauthorized access, modification or denial of services, etc). In this research paper, the proposed work plan is to eliminate security concerns using cryptographic algorithm and hashing algorithm.
