  This technology usually uses the processor communication interface and makes use of the protocol, the encryption algorithm or the security flaw in these algorithms to carry on the attack. A typical example of a successful software attack is an attack on the early ATMELAT89C Series MCU. An attacker using a single chip erase operation of the timing design of the loopholes in the procedures in the use of self erase lock bit encryption, stop chip program memory erase the next data operation, so that the encryption chip not to turn the encryption chip, then the programmer readout chip program.
