Secure file storage in cloud using transparent cryptography algorithm

Abstract

Cloud Computing is nowadays a growing market these days. The most common usage of cloud computing is backup, in which large amount of data is stored. There is a increased use of cloud computing in various organisations such as IT industries. When the user requests the data, it can be reclaimed from the cloud. For the security of data in cloud various techniques such as cryptography and stenography is used. For high level security to data in cloud computing a single algorithm won’t be effective. A new security algorithm is proposed in this paper using Transparent key cryptography algorithm and stenography. The challenging issue in cloud computing is to provide security to the data stored in the cloud. The most popular Transparent key system is Data Encryption Standard (DES), Advanced Encryption Standard (AES), RSA and blowfish algorithms are used to provide security to the data. The cloud computing benefits in a way that accessing of data through internet with low cost. The multi threading technique is used to encrypt each and every part of the data using different type of algorithm.
