The unmatchable progress in Information Technology based Products have encouraged the customers to use free unlimited and ever available cloud storages. The Cloud Storages save hardware investment of customers for storage. Rapid Data migration into cloud storages had been expected by IT industry with all of these developments. However, the growth of data migration has not adopted the pace as expected because of Data security and Speed of cryptographic algorithm’s issues in cloud.
In this paper, we are discussing mainly two mostly used Cryptographic algorithms AES and 3DES and in later section we are also comparing AES, 3DES with RC6, Twofish and Blowfish and we are analyzing the performance of these algorithms in terms of encryption and decryption time taken depending upon the four factors namely file type, file size, key type and key size.
For performance analysis, we are introducing in-house developed Crypter tools where we have integrated five cryptographic algorithms 3DES, AES, RC6, Twofish and Blowfish.The Crypter tool is deployed in Amazon Cloud and Tool is capable to encrypt and decrypt different types of files (in terms of size and format) depending upon variable or fixed type of key using AES, 3DES, RC6, Twofish and Blowfish and The performance of these Cryptographic algorithms 3DES, AES, RC6, Twofish and Blowfish can be analyzed in terms of time taken depending upon different types of files and different types of Keys. Analysis of the result obtained will help the user’s to take decision regarding the selection of best symmetric algorithm to be used while uploading data in cloud.
