Extended Abstract: Towards Physical-Layer Authentication for Backscatter Devices

, 2020
Backscatter communications relieves sensor tags from the energy-intensive task of generating their own radio waves. This enables sensor tags to transmit their sensor readings at an energy consumption that is several orders of magnitude lower than that of
