Secure Data Storage in Cloud using Encryption Algorithm

The Cloud Computing is a self-motivated term, which gives argument free information outsourcing service, which keep the client from burdens of nearby storage issues. Presently, cloud computing is utilized in numerous areas like military, hospitals, industry, colleges and so on to putting away huge amount of data or information. On request of client, the data or information can be accessed from cloud. Generally, Information can be classified as personal, public, and confidential and all the information is in cloud are stored in someone else’s infrastructure. It is always very difficult to trust on third party cloud providers for confidential and personal data. Even the Big players of cloud industry say that security is the responsibility of both company as well as of their client. Therefore, from the client perspective, when the information is stored on cloud then it should be crypted well so that no other user can be able to read it if they get anyhow access to it. When information stored on cloud it faces so many issues like security of data. For these issues many algorithms designed. However, utilization of one calculation or algorithm is not successful for significant phase of security in cloud. In this research work, with the help of cryptographic algorithms the security issues are reduced. Proposed system improves the security in cloud storage framework using different encryption algorithm like AES algorithm with S- box and Feistel Algorithm. The structure utilizes the information-transferring, cutting, ordering, encryption, merging, unscrambling and recovery cycle to make sure about the enormous information put away in the multi cloud. Cryptographic algorithm is mostly used for sending data over a network in a secure manner and to store data in system in non-human readable form. In addition, cloud computing is a combination of Network, Server, and Storage at Infrastructure level. Therefore, this research work is proposed using cryptographic algorithm to store data in secure manner on cloud.
