Protection of data in unsecured public cloud environment with open, vulnerable networks using threshold-based secret sharing

Abstract

With the recent popularity of cloud computing, public cloud infrastructure is now being offered by many vendors. Many small, medium as well as large enterprises are now moving into public cloud due to its significant business advantages, flexibility and reduced cost. However, public cloud environments are less secure and the complete setup consists of vulnerable public networks. Data is send typically over the internet or very large, open networks which are vulnerable to security attacks. Protection of data is hence primarily important in a public, third-party cloud. This paper is an extension of the previously published work and discusses a general approach to distribute and transmit data in an unsecured environment. We propose an application layer technique of protecting important data in public clouds which are transmitted over public networks.
