Abstract: Cloud has become a new paradigm shift in distributed computing. Cloud computing plays an important role in ease of communication, pricing and serving clients in an efficient manner. The adoption of cloud computing is growing rapidly in many organization. Any user can store his data on remote cloud and can be accessed from anywhere, anytime without any hindrance. The most important concerns about cloud storage are security and privacy due to the user sensitive information is stored on cloud. Our proposed scheme reduces both concerns by doing data division, here the user data is encrypted by using Advanced Encryption Standard(AES) algorithm and encrypted file is divided into equal size multiple chunks and stored on multiple cloud servers. The server will take responsibility of placing the chunks into different cloud servers. In our work, we will discuss both schemes like split and encrypt and encrypt and spilt methods and present cryptographic data division after encrypt proves to be better scheme for secure information and it also prevents unauthorized users to access the data. The implementation and results of our proposed scheme is analyzed to address the concerns of cloud computing.
