Secure and Scalable Key Value Storage for Managing Big Data in Smart Cities Using Intel SGX

This paper advocates for the use of Intel SGX capable chips to deliver a secure and scalable architecture for Big Data processing in the cloud. The paper provides a novel Key-Value store service designed to use these new security capabilities as well as delivering a flexible mechanism to store hot, cold, and warm data using data replication, network coding, and hybrid mechanisms. We also describe various representative data streams from smart city sensors and applications gathered in Brazil used to tailor and guide our system design.
