Abstract: Cloud computing is a new concept of the modern world. Cloud computing combines all the services models and technologies together to deliver IT enterprise. The objective of this paper is to provide the security to end user to protect files or data from the unauthorized user. Privacy is an important issue for any technology through which unauthorized user can't access your file or data in a cloud. The main aim of this paper is to design and propose an architecture that can help to encrypt and decrypt algorithm. In this paper, we are presenting an encryption algorithm to deal with the privacy problems in cloud computing and protect the data stored in the cloud.
Keywords: Cloud computing, cloud deployment model, secure framework for cloud computing, encryption and decryption algorithm.
