SECURE FILE STORAGE IN CLOUD USING HYBRID CRYPTOGRAPHY

Abstract

Cloud computing is originated from earlier large-scale distributed computing technology that can be rapidly provisioned and released with minimal management effort or service provider interaction. In Cloud computing, both software and files are not fully contained on the user’s computer. File security concerns arise because both program and user's applications are residing in provider premises. The cloud provider can solve this problem by encrypting the files using an encryption technique. File security model to provide an efficient solution for the basic problem of security in a cloud environment. To solve this concern encryption techniques like AES, DES and RSA are used. LSB steganography is also used to store the data. Keywords: - AES, DES, RSA, LSB steganography, cloud, cryptography
