Brute Force Chip Attack include invasive and semi-invasive microcontroller cracking, hardware attacking will be able to get access to embedded memory such as flash and eeprom memory, then readout firmware from Microprocessor memory;
MCU Attack has different meanings for cryptography and semiconductor hardware. In cryptography, a brute force chip attack would be defined as the methodical application of a large set of trials for a key to the system. This is usually done with a computer or an array of FPGAs delivering patterns at high speed and looking for success.
