Modelling Traffic Analysis in Home Automation Systems

Abstract

The threat of attacks on Home Automation Systems (HASs) is increasing. Research has shown that passive adversaries can detect user habits and interactions. Despite encryption and other measures becoming a standard, traffic analysis remains an unsolved problem. In this paper, we show that existing solutions from different research areas cannot be applied to this scenario. We establish a model for traffic analysis in Home Automation Systems which allows the analysis and comparison of attacks and countermeasures. We also take a look at legal aspects, highlighting problem areas and recent developments.
