Targets

The target device is the Raspberry Pi 4B board with a Broadcom BCM2711 SoC. This is the same as the target used in [1]. It features a quad-core out-of-order ARM Cortex-A72 (ARMv8, 64-bit) processor, operating at a maximum frequency of 1.8 GHz. This device lacks hardware support for AES. It runs on the Bullseye version of the Raspberry Pi OS (Debian Linux). We execute a C-based unprotected implementation of AES-128 for our experiments without computer optimisations. The considered target is the first round of AES after the AddRoundKey.
