SMARTCRYPT: SECURE STORING AND SHARING OF TIME SERIES DATA STREAMS IN IIOT

Abstract

To provide ubiquitous access, scalability and sharing possibilities, the Industrial Internet of Things (IIoT) applications 
utilize the cloud to store collected data streams. However, secure storing and sharing of the massive andcontinuously 
generated data poses significant privacy risks, including data breaches. This paper proposes SmartCrypt, a data storing 
and sharing system that supports analytics over the encrypted time series data. SmartCrypt enables users to secure 
and fine grain sharing of their encrypted data using a novel symmetric homomorphic encryption scheme. Simulation 
results show that SmartCrypt reduces query time by 17% and improves throughput by 9% over the benchmark scheme.
