Secure Computation in Cloud Environment

Abstract — This paper presents an overview of security issues in cloud environment and use of fully homomorphic encryption scheme to provide blindfold computation of data. Though there are various homomorphic encryption schemes available but most of them are designed to work in ideal conditions only and not all schemes are fully homomorphic. In this paper we present a secure banking model for outsourcing banking services into cloud, which will enable the banks to trust the services of cloud without the need to worry about the security of customer data
