Data security in Cloud Computing using Cramer - Shoup cryptosystem

Cloud computing is an emerging technology which has become today's blistering research area due to the advancement of increased connectivity and it is most interesting and attractable technology which offers the on demand services to the users over the Internet. Since Cloud Computing stores the user data and allows the user to work on the cloud system and so the security has become the main concern which creates threat and tries to deploy the Cloud environments. Even though the Cloud Computing is efficient, there are many challenges for data security, which may take away the users from using the cloud computing. To ensure the security of data, we proposed a method by implementing Cramer - Shoup cryptosystem.
