STUDY OF LATTICE BASED FHE FOR CLOUD DATA SECURITY
Main Article Content
Abstract
Cloud Computing is an transpiring trend in the modern world. It is a way of holding the Internet to use software or other IT services on demand. Due to its fast growth and popularity, number of users deposit their data and applications on the cloud. The impressive growth in cloud computing has proved to be promising innovation and more suitable for storing data and applications remotely. But its uses improvement is hindered by the security issue. Cloud doesn’t provide more security for its services and storage purpose. The traditional security approach of encryption doesn’t make cloud fully secure. So there is a need to develop such a technique which increases the security level of cloud. In order to solve the problem of data security in cloud computing system, lattice-based cryptographic schemes implements the so called “Fully Homomorphic Encryption (FHE) schemeâ€, which allows processing directly on encrypted data and holds the promise eventually to solve the security problems with cloud computing. In this paper we survey on the existing lattice based FHE encryption techniques. Fully homomorphic encryption is a good solution to enhance security measures of cloud system that handles critical data. This makes cloud computing more stable and solid.
