Abstract
With the increasing demand of Cloud based resources, the customers have been attracted to the various offerings of cloud computing and mainly it has been seen that the Cloud storages have been centre of attraction because of free limited storage for users. Customers are moving their documents into cloud storages because of various options in cloud storages. We are using various mobile based apps to store images in our system but due to limited storage capacity of our system we prefer cloud storages for storing different files specially images. The image files include files of various formats like JPG Image Files, GIF Images, JPEG Files etc. The image documents on Cloud or server repository is increasing rapidly. Therefore, it becomes necessary to ensure confidentiality, integrity and authenticity of document or information over cloud storage and in addition, there must be some mechanism that helps users for fast encryption of their image to be stored in cloud and fast decryption of same image from cloud to their devices. Since the service level, agreements are very strong and there is no fear to keep the data in cloud because of strong SLA implementation policies. Therefore, we must investigate Conventional algorithm’s efficiency over cloud in terms encryption time, decryption time, key sizes. In this paper we will analyse the performance for exchange of Images with various block cipher SKC algorithms specially 3DES, AES and Blowfish to find more efficient symmetric block cipher algorithm in the term of encipherment and decipherment time at different settings like variable file sizes with fixed key sizes, variable file sizes with variable key size, Fixed file sizes with fixed key size and Fixed file sizes with variable key sizes.
