Abstract :
Cloud computing has brought good impact on the way, we use ICT resources. We are using various offerings of cloud computing which includes Flexible Computing Power,Flexible Storage capabilities, Platform as a service,Infrastructure as a service and software as a service on pay per use model. Nows a day the Customers are using their Smartphones to migrate their data in cloud storages but keeping in view of security issues in cloud storages, one must think of encrypting their data in cloud storages. Since in cloud storages, we keep various documents and we must think of fast encryption and decryption symmetric algorithm. but in literature, we do not find work that deals with investigation of efficient cryptic Algorithm for audio or video Files in cloud storages. In this paper, we are analyzing the performance of Cryptographic algorithms AES, Blowfish and DES algorithms in terms of encryption and decryption time taken depending upon the four factors namely file type, file size, key type and key size in case video files which may includes MPG, MPEG formats. For performance analysis, we have used Crypter tools 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, Blowfish and DES algorithms and the performance of these Cryptographic algorithms AES, Blowfish and DES algorithms 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 video data in cloud.
