What is MCU decryption? This is our
Frequently Asked Questions. Now let’s talk about this technology.

Microcontrollers (MCU) IC generally have internal EEPROM / FLASH program for users to
store data. To prevent unauthorized access or copy microcontroller program of IC (IC
CRACK), most of ICs are encrypted with the encryption lock orientation or lock-bit bytes
to protect the IC program. If the programming lock-bit encryption is enabled (locked),
you can’t use ordinary programmer reads the program directly within IC, which is called
encryption or microcontroller chip IC encryption. IC MCU cracker with special equipment
or home-made equipment, take the advantage of single IC design flaw or software defects,
through a variety of techniques, can extract key information from the IC chip, access
to program inside microcontroller IC chip, which is called IC CRACK.

IC CRACK also known as mcu crack, ic attack, IC Reverse Engineering, ic decryption,
mcu code extraction, ic break, but strictly speaking these types of call are not scientific,
but it has become accustomed to it is called, we roughly define CPLD decryption, DSP
decryption as IC CRACK.

MCU is only one type of ICs which can load program. IC which can load program and
can also encrypted includes DSP, CPLD, PLD, ARM, etc. There are also IC chips with
special encryption algorithm for encryption IC chips and manufacturer code verification ,
such IC chip can achieve the purpose of preventing copying of electronic products.
