Broadcom/Cypress WiFi chips commonly hold a microprocessor, also called D11 core, that handles all real-time related 802.11 MAC tasks in form of a programmable state machine (PSM). It is directly connected to the chip's PHY components as well as its non-real-time related parts. Successful attacks on the D11 core would therefore pose a high risk on the whole device. Especially, as the chip is constantly exposed over its wireless interface.
Although the D11 core's architecture and instruction set are mostly proprietary, disassembling and assembling of microcodes (D11's firmware) is possible due to previous reverse engineering efforts. This in turn allows analyzing, modifying and on-chip debugging of microcodes. However, the current related processes are error-prone and time consuming. To improve those tasks, a basic emulator that can interpret the proprietary instruction set and perform corresponding calculations and memory/register accesses was designed and implemented in prior work. But, in order to properly run microcodes on the emulator, several peripherals (e.g. timers, crypto engine, tx/rx engines, PHY interface, ...) that directly influence the PSM's flow need to be emulated additionally.
In this thesis, we want to analyze peripherals that are directly connected to the D11 core and simulate their behavior to the existing emulator.

C and Assembly skills are recommended, as well as experience and/or interest on reverse engineering, IEEE 802.11 MAC, and low-level programming.
