Abstract
IoT systems consist of Hardware/Software systems (e.g., sensors) that are embedded in a physical world, networked and that interact with complex software platforms. The validation of such systems is a challenge and currently mostly done by prototypes. This paper presents the virtual environment for simulation, emulation and validation of an IoT platform and its semantic model in real life scenarios. It is based on a decentralized, bottom up approach that offers interoperability of IoT devices and the value-added services they want to use across different domains. The framework is demonstrated by a comprehensive case study. The example consists of the complete IoT “Smart Energy” use case with focus on data privacy by homomorphic encryption. The performance of the network is compared while using partially homomorphic encryption, fully homomorphic encryption and no encryption at all.As a major result, we found that our framework is capable of simulating big IoT networks and the overhead introduced by homomorphic encryption is feasible for VICINITY.
Highlights
Nowadays, the number of applications in which IoT networks are deployed grows rapidly
We present a simulation framework to validate the security of a smart energy use case, which is enabled by using homomorphic encryption
For the partially homomorphic encryption, we integrated the libhcs [40] library into our encryption service. This library implements “a number of partially homomorphic encryption schemes” [40], yet we focused on the implementation of the Paillier encryption scheme for additive homomorphic encryption, which is necessary for our given use case
Summary
The number of applications in which IoT networks are deployed grows rapidly. These infrastructures operate in different domains such as smart cities, energy, eHealth, and transportation and behave as isolated islands in the global IoT ecosystem [1]. Their secure interconnection is a big challenge that still needs to be resolved. One promising approach towards interoperability of IoT networks across different domains is proposed by the VICINITY project. We present a simulation framework to validate the security of a smart energy use case, which is enabled by using homomorphic encryption. The real micro-service for the encryption is integrated into the simulation as hardware in the loop with the approach presented in [2]
