I'm in car audio products, want to know how to prevent piracy, new products have good method?

CodePudding user response:

Anti-piracy, there are many ways you can do it to the software can also be hardware design

CodePudding user response:

Software? Hardware? What kind of good, can say specific?

CodePudding user response:

Hardware need to spend money, affirmation is safer! Because the software is still not out of the product itself, belong to product of MCU protective safe enough

CodePudding user response:

So why security hardware, hardware is bad?

CodePudding user response:

Main is such, don't like eggs in one basket, hardware is involved, so it is very important to the hardware level, but also must be safe and reliable to complete protection

CodePudding user response:

For hardware encryption, that is to say the good hardware, missed it won't run over

CodePudding user response:

That what is good security, whether do I contact before certification is ok,

CodePudding user response:

Certification has some security, but I think is not very enough, because belong to one of the more ancient scheme

CodePudding user response:

Yes, certification schemes to see in high security requirements of the industry is not enough, because the essence or MCU security decisions, unreliable

CodePudding user response:

My friend used a LKT encryption chip, can achieve good protection effect, is said to be doing programming

CodePudding user response:

Programming? MCU programming can also ah, why can programming is safe???????

CodePudding user response:

Because (part) microcontroller has security mechanism, internal storage after writing can fuse, fuse after internal procedures and data cannot be read from the outside and modify,

CodePudding user response:

Of course different, MCU has a variety of debugging method is convenient, also to copy board, provides a convenient, encryption chip is different, more conservative to breakthrough

CodePudding user response:

Specifically, project safety

CodePudding user response:

Simple said that once the clipper chip can realize programmed and operated, so piracy is facing, before: pure crack MCU, encrypted: crack MCU + crack encrypted chips (with valid program)

CodePudding user response:

So, the security of encryption chip is determine the overall safety?

CodePudding user response:

But if be monitored on line? If imitation encryption chip can be cracked

CodePudding user response:

The monitoring line? Data on such a simple question, the line is not fixed to bai, program logic and data encryption, such as operation can meet the requirements

CodePudding user response:

LKT more do ready, my friend recommended to me, anyway, now didn't meet the copy board

CodePudding user response:

Look forward to, this chip is difficult to buy? Is domestic or abroad

CodePudding user response:

The bad with domestic and foreign, mainly function is relatively simple, it is difficult to do personalized customization

CodePudding user response:

The FPGA to customize a?

CodePudding user response:

Indeed, we Chinese people's wisdom is very severe ah, domestic refueling!
