On-board diagnosis device, want protection, prevent piracy how to implement?

CodePudding user response:

Need encryption chip is used to design, to do protect

CodePudding user response:

Encryption chip is? What good

CodePudding user response:

Program where,

CodePudding user response:

Just as its name implies is responsible for encryption protection chip, program or data

CodePudding user response:

What is the principle? How can achieve encryption?

CodePudding user response:

Very simple, the content inside is useful and can't access to the outside world must pass the chip

CodePudding user response:

That if the line is detected?

CodePudding user response:

Data are addressed and encrypted, so there is no question of the

CodePudding user response:

Be cracked if the MCU end, I'm afraid I can't?

CodePudding user response:

Ha ha, this way of derived data encryption, security is limited, must use the class algorithm transplantation, the biggest difference is that effective procedure in the chip, take in the chip

CodePudding user response:

A: what's recommended, I want to see the principle scheme, feeling is not very understand

CodePudding user response:

Ah, what is the specific principle, protection way is what?

CodePudding user response:

Can be stored program encryption chip, and can run the program, the clipper chip will become a effective carrier of cannot be skipped

CodePudding user response:

It seems that say, microcontroller advantages like, what's the difference

CodePudding user response:

Difference is very big, debug method is limited, unlike microcontroller a variety of methods, the other is to detect and internal data storage approach is a special

CodePudding user response:

I want to know what to do on a line simulation?? Although I don't know, but still can simulate roadmap,

CodePudding user response:

This is easy to implement, as long as the simulation is not good, plus interference or each run data dynamic can

CodePudding user response:

It seems as if is good, isn't it all encryption chip support this

CodePudding user response:

Surely not, it seems that the domestic only LKT do this, is the famous

CodePudding user response:

, domestic or abroad?

CodePudding user response:

At home a little bit stronger, foreign to this set of support services is weak, so takes a lot of simple solutions, suitable for security is none too high

CodePudding user response:

The free so really want to have a look at, in the future there will be a need to use, thanks to explain!
