To study the security and privacy aspects of a smart irrigation system, it is essential to have a system prototype in place. Towards achieving this the prototype of a standalone sensor-hub with sensors, battery pack and XBee, integrated around Arduino, for the application of indoor smart irrigation has been developed.
A Network Packet Broker (NPB) based anomaly detector that can be positioned at the egress port of the edge device of an IoT system has been developed. Setup is that the anomalies in the normal traffic have been introduced using an off the shelf Ethernet tester. The performance of the system has been evaluated with varying severity levels of anomalies, measured in terms of bandwidth of the traffic generated by the Ethernet tester.
Digital Twin for Smart Irrigation system attack detection has been developed using NetSim, IoT Network simulation software. This involved the mapping of the Physical sensors, 5G Network and the Cloud server to the logical sensors, NetSim 5G Network and logical Server where malicious nodes from Logical Server inject Syn Flood to the Logical sensors. The impact of this is seen as a drop in the application throughput is tested by increasing the malicious nodes.
An approach of Intrusion Detection System (IDS) based on the time difference between samples is proposed. An XGBoost based classifier is evaluated using this synthetic data. The quality of this synthetic data has been computed in terms of Training on Synthetic data and Testing on Real Data (TSTR) and Prediction Capability (PC). This synthetic data can be generated with multiple levels of Attack Impact Factor (AIF), where the level is determined by how difficult it is to classify the data accurately.Security Implication due to slicing have been studied for IoT Network.
Systematic studies of Two Novel Types are attacks which are capable of bringing down entire IoT network were done as part this studies, namely,1) CC- EDA – Cloud Container-Based Energy Depletion Attack.and 2) CC-SPA – Cloud Container-Based Synergistic Power Attack.
Further work is to be taken in
The development of secure RISC V processor based SoC for the edge device.
Enhancing the digital twin to represent the actual smart irrigation system.
Edge based intelligence using FPGAs.
Live stock monitoring system and its security.
Agricultural waste management system.
