Multiplicative Homomorphism Ensures Confidentiality Of Data
Though Cloud Computing has become an emerging technology; still it cannot be used by everyone due to lack of
data confidentiality when stored on cloud. Also while performing computation on data, it requires decrypting data before any
computation. If the cloud provider is not trusted this may violate data confidentiality. We can ensure the confidentiality of data
and computation on cloud using homomorphic encryption. In this paper, we described how homomorphic encryption helps to
ensure data confidentiality.
