Comparative Analysis of Various Cloud Security Frameworks

Cloud is one of the technologies, the use of which will be increases day by day for different purposes as per user's requirement. Mostly this technology is used for storage purpose as because of this the users need not to have any hardware storage devices instead of that their data will be stored on the network. These systems have to be more secure so that they provide confidentiality, privacy and protection for their customer's satisfaction. Various algorithms were developed to secure cloud frameworks but still these algorithms are not able to meet the requirements of the users. To find out the lack, a comparison of existing security architectures will be covered in this paper where we will consider three different security architectures and will compare these on the basis of Computation Time (for both encryption and decryption), Computation Cost (for both encryption and decryption), and Cipher Text Size
