When it comes to reverse engineering smartcards and microcontrollers, both structural and program-code reverse engineering are required to understand how the device works. First, the security protection needs to be understood by partial reverse engineering of the chip area associated with it. Thus if memory bus encryption was used, the hardware responsible for this should be reverse engineered. Then, finally, the internal memory contents have to be extracted and disassembled to understand device functions.
