BitBuster is a low-cost platform for hardware security education, research and competitions. It consists of the main BitBuster base board (pictured below), which is best described as a portable oscilloscope and logic analyzer. In addition to the external channels on the left (2 analog, 8 digital), it also features a reverse DDR4 SODIMM slot for easily connecting custom boards.
The PowerSlot UNLEASHED RP2 is our first of these boards It mostly mirrors the reference design of the Raspberry Pi Pico in SODIMM form, but includes the hardware for power analysis of the RP2040 cores directly on the board. Additionally, it is possible to tamper-evidently lock the RP2040 bootloader for in-person capture the flag competitions.
An example challenge about RSA key extraction using power analysis is the CookieCrasher c.1 that was used during the finals of the Cyber Security Challenge Germany 2023.
