Chip to decrypt a common problem, chip decryption
First, what is the decryption chip?
A: The chip decryption, also known as (MCU decryption / IC decryption), the IC in the general product prior to production encryption, direct use of the programmer is not allowed to deliver the program, usually the ID error. But sometimes customers for some reason, you need to get the chip inside the program, used to refer to the research study to find the missing information, or copy some of the chips, which need to do the decryption chip. Decryption chip is a certain amount of equipment and methods, directly from the microcontroller encrypted programming file, can copy the chip is programmed or disassemble own reference. Decrypted can guarantee that the sampling function and the master of the original customers, and can be programmed file (machine language) to the customer, the customer can freely programmed. If you need us to help the agent to burn, we can provide the service.
Second, why you want to decrypt?
A: Because many products are engineers developed in the process of burn burner is encrypted, if you want to get inside the program, on the need for chip reverse study, by the device or method can not directly access the program, so it is necessary to decrypt.
Decrypted What is the procedure like?
A: decrypted is the program, but because the manufacturers are not the same, often the format:
BIN, HEX, the JED, POF, SOF, OTP, S19 or CDS and other formats are directly burn the program.
, IC decryption is injurious to the master?
A: The single-chip decryption There are two approaches, one is a software-based, known as non-invasive type of attack, to make use of some software, such as homemade device similar to the programmer, this method does not destroy the master (decryption chip in the non-encrypted state); there is a hardware-based, supporting software, known as invasive attack, this method need to peel the master (openings called Kaifeng, decapsulation), and then do the circuit to modify (usually called the FIB: focused ion beam), this destruction of the chip shape structure and chip die line affects only the encryption, do not change the functionality of the chip itself.
, Decryption the stepmother piece could be returned to us?
A: The principle can be. Microcontroller to do the hardware decryption chip openings, we modify the circuit traces, we do not want our technology leakage, so this method must not return to the master! Tiny traces of our decryption software decryption, but this leak is unlikely, in exceptional circumstances can be returned to the client, but we need to charge a fee, generally 1K or so, this is mainly used to clear my decryption the traces. , Decryption cost?
A: decryption company will offer different film, of course, different film price is not the same, basically offer based on the difficulty and workload, and market demand, detailed consultation with the Corporate Banking Department.
, Chip to decrypt the success rate?
A: the strength of the different companies and technical, general, there is no 100 percent guarantee, generally follow the principle of the more expensive the higher the success rate.
Eight, what is soft encryption?
A: Encryption is a programmer in the process of the design process set encryption.
Nine encountered soft decrypt how to deal with?
A: is also a reverse study, the first program from the film which "read", and then read out the procedure to analyze, modify, so as to achieve the purpose of cracked soft encrypted.
10, how to verify that the decryption is successful?
A: In general, the verification requires two steps, first step, the decryption provides the chip used in the original plate above, if there is no problem, then the next step, namely to buy a new, empty chip back, according to decrypt the company the procedure to burn, and then verify that, if confirmed to use, the basic judgment of the decryption is successful, of course, means, except for some engineers to write programs.
The decryption Why East guide science and technology?
A: East conduction technology is a professional PCB copy board and decryption chip companies, the company has its own chip decryption Division, the company has a group of senior engineers, the company decrypted too many success stories, the company promised decryption is not successful, 100% refund. Because we are professional, honest and trustworthy, because the strength of our technology, select the east guide, select the shortcut, select the successful
