IC Chip Crack is a kind of technology which use abnormal operational working condition terms to make the processor go wrong, and then provide extra visit to break IC. The most widely populated way of Crack MCU chip includes voltage shock and time clock shock.
Low voltage and high voltage attack can be used to prohibit the protective circuit working or compel processor to operate the wrong operation. Time clock changes in instantaneous condition when attacking can effectively protect the circuit of IC chip from being damaged especially for the content inside the ROM. Power supply and time clock change in instantaneous condition can affect the single processor’s decode and instruction when attack the IC chip.
