A Cloud Computing Security Solution Based On Fully Homomorphic Encryption.

Computer Engineering

Cloud Computing is an emerging trend in the modern world of computing. Because of its rapid development its become more popular. Due to its popularity number of users deposit their data, their applications on the cloud that means rate of accessing cloud services is greater. But its popularity, its uses improvement is hindered by the security issue. Cloud doesn’t provide more security for its services and storage purpose. So there is a need to develop such a techniques which increases the security level of cloud. The encryption of data which is stored in remotely fill the security gap between this. To solve the problems of data security in cloud computing system, by introducing fully homomorphism encryption algorithm in the cloud computing data security for encryption purpose. The proposed homomorphic encryption system helps to store the data on cloud computing. And in the cloud storage their data is still safe also check for the users privileges . All cloud operations should be done according to the rights provided by the cloud admin. In proposed system on cloud computing perform encryption on data which take as an inputs and processing is done without knowing their contents and this data is retrieved by performing decryption only for authorized users by checking their privilege. In our system, we establish security precautions in worm containment and intrusion detection against virus, worm, and distributed DoS (DDoS) attacks. We also deploy mechanisms to prevent online privacy and copyright violations of digital contents.
