Raphael Schermann, Simone Bussa, Rainer Urian, Ronald Toegl, Christian Steger · 2024
Anonymity and pseudonymity are important concepts in the domain of the Internet of Things.

However, privacy should also include anonymity or pseudonymity of the device identity. This means there should not exist any correlation handle to associate different communications done by the device.
