We demonstrate an evaluation setup for the energy-efficient usage of hardware-based security mechanisms. We implemented a small use-case scenario for the surveillance of critical areas with both software and hardware-based security mechanisms. For the surveillance, we use passive infrared sensors (PIR) attached to IRIS sensor nodes. The detected trespassers are reported to a base station and shown in a graphical user interface. We use asymmetric cryptographic mechanisms to guarantee the integrity and authenticity of the reported trespassing events. In the demonstrator, we will show how much energy can be saved by using hardware-based security mechanisms compared to the software-based approach. For the energy measurements, we employ hardware from the SANDbed testbed at the Karlsruhe Institute of Technology (KIT).
