Tracking Data Trajectories in IoT
Proceedings of the 5th International Conference on Information Systems Security and Privacy, 2019 The Internet of Things (IoT) devices access and process large amounts of data. Some of them are sensitive and can become a target for security attacks. As a consequence, it is crucial being able to trace data and to identify their paths. We start from the specification language IOT-LYSA, and propose a Control Flow Analysis for statically predicting ...
