Security implementation on Cloud Storage using New Public key algorithm based on block cipher

Cloud computing is a new era of the modern world. It is an emerging paradigm which has become today's hottest research area due to itsability toreduce the costs associated with computing. The main problem associated with cloud computing are data privacy, security and authenticity, the aim of our proposal to give the cloud data storage models and data security in cloud computing system. Here we propose an efficient method for providing data storage security in cloud computing using new public key algorithm based on linear block cipher. This proposed algorithm, which has been proposed and proved other research area such as Data encryption, Ecommerce, Digital signature etc., here, we are implanting the same algorithm on Cloud Computing. In this algorithm some important security services included such as key generation, encryption and decryption that are provided in cloud computing system. The main scope of this paper to solve the security issues in both cloud providers and cloud consumers using new cryptography methods.
