A survey on Fully Homomorphic Encryption
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2015, Vol 17, Issue 6
Abstract
Abstract:Cloud computing is an ever-growing field in today‘s era.With the accumulation of data and the advancement of technology,a large amount of data is generated everyday.Storage, availability and security of the data form major concerns in the field of cloud computing.This paper focuses on homomorphic encryption, which is largely used for security of data in the cloud.Homomorphic encryption is defined as the technique of encryption in which specific operations can be carried out on the encrypted data.The data is stored on a remote server.The task here is operating on the encrypted data.There are two types of homomorphic encryption, Fully homomorphic encryption and patially homomorphic encryption.Fully homomorphic encryption allow arbitrary computation on the ciphertext in a ring, while the partially homomorphic encryption is the one in which addition or multiplication operations can be carried out on the normal ciphertext.Homomorphic encryption plays a vital role in cloud computing as the encrypted data of companies is stored in a public cloud, thus taking advantage of the cloud provider‘s services.Various algorithms and methods of homomorphic encryption that have been proposed are discussed in this paper
