  The technique is to directly expose the internal connection of the chip, and then observe, manipulate, interfere with the MCU to achieve the purpose of attack. For the sake of convenience, more than four people will be divided into two types of attack technology, a type of invasive attack (physical attack), this kind of attack requires the destruction of package, then use semiconductor test equipment, microscopes and micro positioning device, in a special laboratory spend hours or even weeks to complete. All of the micro probe techniques are invasive. The other three methods are non intrusive attacks, the single chip will not be attacked by physical damage. In some occasions non intrusive attacks are particularly dangerous, because the device is usually required for non-invasive attacks can be made and upgraded, and therefore very cheap.
