A comprehensive evaluation of cryptographic algorithms in cloud computing

Cloud computing is a new mechanical and industrial art for hosting the applications and it is flexible, cost-effective, and user-demand platform. It provides the way to share distributed resources and services to all the business or consumer IT sector from desktop and portable PCs over the internet. The advantage of cloud storage is easy access, reduced hardware, low maintenance and installation cost, so each and every organization working with cloud. But it harder to maintain data security, privacy and compliance. Hence it raises serious issues regarding user authentication and data confidentiality. Therefore it is proposed to implement simple data protection framework which performs authentication, verification and encrypt data transfer and thus maintains the data confidentiality. This paper describes about the performance of different security algorithm: AES, RSA and MD5, for ensuring the secure framework.
