Encryption chip ALPU-C/ALPU-CV
Encryption chip ALPU-C/ALPU-CV
The Algorithm License Unit (ALPU) is an encryption chip product used by our company for system copyright protection. This is an authentication encryption chip that uses a random variable exchange system. It integrates more than 10,000 logic gates in a small package such as SOT-23F . ALPU communicates with the system CPU in a cryptographic manner, and the CPU detects the ALPU encryption chip in key situations such as system startup. Therefore, even if the pirated system copies the firmware in the PCB, the kernel or even the memory, the system still cannot work without the ALPU chip. In addition, because we use a single-line direct sales channel with 100% secrets for the ALPU encryption chip, the pirated system is simply impossible to take advantage of.
The working principle of the ALPU series encryption chip is to write the key in the boot area of the protected device, thereby preventing the software code in the device from being maliciously copied. This is manufactured by ASIC, that is, the encryption chip in hardware, so the encryption is very strong. The encryption chip currently used is of EEPROM mode, and the required software password must be put in the space of this encryption chip. However, the EEPROM chip can be opened and the settings inside can be seen, so it is easy to copy.
The ASIC hardware method is not easy to copy the encryption chip, and the data inside can be known only after the entire semiconductor is analyzed side by side. However, this kind of thing is difficult to implement and expensive, so most people have no way to copy to such an encryption chip.
The principle of this encryption is software + hardware. The software calculation result and the hardware calculation result must be consistent to pass the test. What prevents the binary code from being directly copied from the memory, and the original product can be copied by simply copying the board. If there is a master who can disassemble the binary file, find the entry of the code that calls our library in your program, and bypass it, of course our encryption will be cracked. Of course, this is theoretically possible. In reality, it takes extremely high technical means and a lot of time to complete such a thing, so it can be regarded as a small probability event that is about zero, and we use a customized single-line direct sales channel. , Even if the other party is cracked, the ALPU encryption chip dedicated to you cannot be obtained.
