Chip decryption question and answer

How much does the chip decryption cost? How much is it?

Date: 2016-10-21
The price range of chip decryption is relatively large, depending on the specific model!

Since engaging in chip decryption, I have often received a variety of questions from customers. Today we explain why chip decryption is also targeted at chips, so there will be such a big difference in price? Some chips cost only a few hundred yuan, while others require tens or even hundreds of thousands?

First of all, the price of chip decryption is linked to our R & D expenses. The higher the cost of the solution, the higher the corresponding decryption price. I believe this need not be explained too much by most customers, so they are different. The cost of solution development is different for different companies due to their different technical strengths. Another point, such as the 51 single-chip microcomputer of the ATMEL series, has been in the country for decades, and all technical information is published to the public. Any Everyone can easily obtain this kind of information, so the research on the decryption scheme will be more handy, and the natural cost will be small. Most importantly, the encryption method of this chip is generally not too complicated, and the decryption operation cost Also low. Some chips, such as STC microcontrollers, are designed by the United States and domestically manufactured by Hongjing. These chips learned the lessons of 51 series microcontrollers that are easy to be cracked when they were designed, and improved the encryption mechanism. It has been completely encrypted at that time. The user program is written by the ISP (In-System Programming) / IAP (In Application Programming) mechanism. When programming, it is programmed while verifying, and there is no read command. These are greatly increased. Understanding the difficulty of secrets. STC chip space is divided into: 1, BOOTLOAD 2, application code 3, EEPROM. Our decryption is mainly to crack the BOOTLOAD area, and then read the program. In view of this, the latest version of the STC chip removes the BOOTLOAD area. All of the above require us to spend a lot of manpower and material resources to develop a decryption solution, and the cost of many devices is millions or tens of millions, so we can only borrow them. The overall cost is much higher.

In addition, due to the different applications of the chips on different devices, even the same model, there will be great differences in decryption costs; some programs are so full that they cannot be cracked, especially some devices will use special chips The decryption is very difficult, so the cost of decryption will be several times, dozens or even hundreds of times higher than that of ordinary chips. Therefore, you need to communicate the detailed model and features of the decryption with our customer service carefully, and our customer service will give the company's standard decryption price.
