MCU crack chip decryption methods

Source: IC declassified. The attacker took advantage of the loophole in the timing design of erasure operation of the series of microcontrollers. After erasing the encrypted lock bits, the self-programmed program was used to stop the next erasing operation of the on-chip program memory data, thus turning the encrypted microcontrollers into non-encrypted microcontrollers, and then using the programmer to read out the on-chip program.

2. Electronic detection attack usually monitors the analog characteristics of all power supply and interface connections when the processor is in normal operation with high time resolution, and attacks are carried out by monitoring its electromagnetic radiation characteristics. Because MCU is an active electronic device, when it executes different instructions, the corresponding power consumption also changes accordingly. In this way, by using special electronic measuring instruments and mathematical statistical methods to analyze and detect these changes, the specific key information in the MCU microcomputer can be obtained.

3. Fault Generation Technology This technology uses abnormal working conditions to make the processor error, and then provides additional access to attack. The most widely used means of attack include voltage impact and clock impact. Low voltage and high voltage attacks can be used to prohibit protection of circuits or force processors to perform erroneous operations. Clock transient hopping may reset the protection circuit without damaging the protected information. The transient hopping of power and clock can affect the decoding and execution of single instruction in some processors.

4. Probe technology. This technology directly exposes the internal connection of the chip, and then observes, manipulates and interferes with the microcontroller to achieve the purpose of attack.

How much do you know about the inside of the MCU crack industry

Chip decryption is also known as IC decryption, MCU crack, single chip decryption. How much do you know about the inside of the MCU crack industry?
The MCU crack industry is a small industry with large profit margins. The whole country seems to be able to decrypt only a few, and not all models can be cracked. Do you know the so-called decryption businesses, can they really decrypt it? An office, a few employees, looking for customers through Baidu bidding, do you think that is the real decryption business?
It is hard to find a businessman that can really decrypt. He can guarantee your decryption cycle and will not find various reasons to fudge customers’ money.
Before the Baidu bar and Baidu know inside, there are many customers to see the reaction, Shenzhen has 2 deciphers of decryption board company, the name of the specific company name can be searched by the vast number of users, they are generally doing this, they have no technology only, through Baidu bidding to find business, business after he brought him They usually go to their peers to do so. The cycle is not guaranteed at all. Secondly, they will find various reasons to increase the price. All the selection of a good copy board decryption company is very difficult and very necessary.
At present, our company’s decryption technicians are also in the DSP chip, the STM32F103 series, the TMS320 series, the Lattice series and those simple such as the whole series of STC, PIC, and other series of chip decryption is absolutely sure. For other series of chips, such as NEC chips, Hitachi, Fuji and some other Hitachi series and CPLD chips, we still do not have very good technical solutions to solve them. In the 2 series of STM32F103 series and TMS320, we have absolute superiority. Welcome customers to open their electricity consultation.
Customers who need to decrypt and copy the board can come to our company and observe all the operation process practically.

chip decryption process

Posted by

Uncovering chip package
The first step in invasive attack is to unwrap chip packages (for short, “open” sometimes called “Kaifeng”, English as “DECAP”, decapsulation).
There are two ways to achieve this goal:
The first is to completely dissolve the chip package and expose the metal connection.
The second one is to remove the plastic package on the silicon core only.
The first method needs to bind the chip to the test fixture and operate with the binding table; the second methods need personal intelligence and patience in addition to the knowledge and the necessary skills of the attacker, but it is relatively convenient to operate in a complete family.
The plastic on the chip can be opened with a knife, and the epoxy resin around the chip can be corroded with concentrated nitric acid. Hot concentrated nitric acid will dissolve the chip package without affecting the chip and wiring. This process is usually carried out under very dry conditions, because the presence of water may corrode exposed aluminum connections (which may result in decryption failure).
Cleaning chip
1. then wash the chip with acetone to remove residual nitric acid and immerse it in the ultrasonic tank.
2. find the position of protective fuse and destroy
3. the last step is to find the location of the fuse protection and expose the protective fuse to ultraviolet light. A microscope with a magnification of at least 100 times is usually used to track the protection fuse from the input line of the programmed voltage input. Without a microscope, a simple search is carried out by exposing different parts of the chip to ultraviolet light and observing the results. Opaque sheets are used to cover the chip during operation to protect program memory from ultraviolet light. The protection of protective fuse can be destroyed by exposing the protective fuse to the ultraviolet light for 5~10 minutes. After that, the content of the program memory can be read directly by a simple programmer.
It is not feasible to use ultraviolet light reset protection circuit to protect the EEPROM unit using a protective layer. For this type of MCU, micro probe technology is usually used to read memory contents. After the chip package is opened, the chip can be placed under the microscope, and it is easy to find the data bus connected to other parts of the circuit. For some reason, chip lock positioning does not lock access to memory in programming mode. With this defect, the probe can be placed on the data line to read all the desired data. In programming mode, restart the read process and connect the probe to another data line, you can read all the information in the program and data storage.
Destruction of protective fuse with microscope and laser cutting machine
Another possible means of attack is to find protective fuse by means of a microscope and laser cutting machine, so as to find all the signal lines associated with this part of the circuit. Because the design is defective, the whole protection function can be prohibited by cutting off a signal line from protective fuse to other circuits (or cutting out the entire encryption circuit) or connecting 1~3 gold lines (usually called FIB:focused ion beam), so that a simple compiler can be used directly to read the inside of the program memory. Yes.
Although most common singlechip has the function of fuse burning to protect the internal code of the single chip microcomputer, the single chip microcomputer is not located in the production of safety products. Therefore, they often do not provide targeted precautions and low security level. With a wide range of applications, large sales volume, large volume of sales, frequent entrustment and technology transfer among manufacturers, a large number of technical data have gone out, making use of the design vulnerabilities of this type of chip and the testing interface of the manufacturers, and reading the internal programs of the single chip computer by modifying the fuse protection bit and other intrusive attack or non intrusive attack batter. It becomes easier.
