Cloud computing is a trending and adapting technology to reduce establishing costs and to access their recourses from anywhere on demand using internet. Obtaining services via internet is much vulnerable for the cloud users. Providing security for data storing in cloud is very much required which will give confidence to the users to adapt and utilize cloud services. There are many encryption algorithms to provide confidentiality for our data over cloud. In this paper, we propose Twofish encryption algorithm, which protects the privacy of individual data. Twofish algorithm has a robust encryption structure to defeat its protection.
