Efficiency Analysis of Cryptographic Algorithms for Image Data Security at Cloud Environment

Abstract

Cloud computing uses a network of remote servers hosted on the Internet to store, manage, and process data. As the cloud is explicitly unsafe, from the time the cloud platform was utilized for storage many researchers and analysts have been trying to develop many encryption algorithms to provide excellent security on the data. The algorithms’ weaknesses, performance and strength should be known to apply a suitable cryptography algorithm to an application. This paper evaluates the efficiency of the encryption techniques AES, DES, 3DES, Blowfish, RC4 and RSA on the basis of image data security and performance in the cloud environment. The algorithms have been subjected to different analytic tests such as differential cryptanalysis, statistical analysis, key sensitivity analysis, and performance analysis to analyses the efficiency of each algorithm for security and performance.
