SISA: A secret-sharing scheme application for cloud environment

Abstract

Security defies one of the galactic barrier when pondering the use of cloud services. Data outsourcing in the cloud (DOC) is conventionally based on data encryption, which imparts impregnable security, but deteriorating the efficiency and rimming the functionalities of cloud. In this proposal we aim to possess them by proposing a secret sharing scheme that depends on partitioning the data and distributed storage over multi-clouds. The scheme used in the proposal uses a combination of symmetric (AES) and asymmetric (RSA) encryption techniques to share the data among the peers in the cloud environment. The proficiency of the suggested scheme has been demonstrated by the empirical results.
