Abstract

Today, cloud computing is used in various fields like industry, military, college, etc. for various services and storage of huge amounts of data. The data stored in the cloud can be accessed or retrieved by user request without direct access to the server computer. But the major concern regarding the storage of data online on the cloud is about the security of the file. Cryptography and steganography are the most commonly used security techniques. So, we have introduced a security that uses a combination of multiple cryptographic algorithms. In this proposed system, Data Encryption Standard (DES), Rivest Cipher 4 (RC4), and Advanced Encryption Standard (AES) algorithms are used to provide security to data. Key information will contain the information regarding the encrypted part of the file, the algorithm, and the key for the algorithm. During the Encryption phase, the file will be split into three parts and each part will be separately encrypted using AES, DES, and RC4 algorithms. Our methodology provides better security and assurance of user data by storing on the cloud server, using AES, DES, and RC4 algorithm.
