A NOVEL CRYPTOGRAPHY BASED SECURITY IN CLOUD COMPUTING

Abstract

Cloud computing is in demand nowadays because of its reliability. It provide us better platform for sharing data, messages, hardware, software and so on without fear of losing data. The number of users in cloud environment and number of threats on their cloud data are also increasing. In cloud computing, most of the researchers focused mainly on three areas, namely security at client’s side, security at network and security at server’s side. In this research I have focused both on security aspect of outsourced data and minimization of the duplication data, which also impacts the security of cloud. I have proposed an effective cryptography based security model which is more effective and secure than existing models in terms of performance and reliability. I have used a novel cryptography technique at client side before transmitting the data for increasing the trust of data owner as well as providing the security. I have also used a hashing function for checking the duplication of data so as to minimize space and bandwidth needed to store and upload the duplicate file.
