Hello, I'm in truck circuit board, want to have a protection to prevent others copying, what method?

CodePudding user response:

Prevent copying, can according to the current mainstream solutions, choose some encryption scheme to do

CodePudding user response:

Specific what can use?

CodePudding user response:

Such as software encryption, data encryption and decryption

CodePudding user response:

I recommend or use encryption chip mainstream way, to the protection of data and programs have good

CodePudding user response:

LKT encryption chip is good, I use this for several years, the product's safety

CodePudding user response:

The elder brothers, specifically about what's good, to point out the theoretical line not

CodePudding user response:

Specifically, the plagiarism is anti-piracy, can protect the program will still have to give priority to

CodePudding user response:

Said is how to implement this thing

CodePudding user response:

A "algorithm transplantation" scheme, which is able to put procedures in the encryption chip shields

CodePudding user response:

Encryption schemes have what, why do you say "algorithm transplantation" safety?

CodePudding user response:

There are various, such as contrast certification, authentication parameters, is what security algorithm transplantation

CodePudding user response:

To ask, what's the difference? The great god, please grant instruction

CodePudding user response:

This is a problem, you want to ah, id authentication, if people want to simulate the same id, device how to judge?

CodePudding user response:

Should be no problem, right? The biggest problem is that the MCU side how to ensure the results?

CodePudding user response:

Circuit board can't copy, can only work about protection and encryption in the chip program, upstairs already said a lot of method!

CodePudding user response:

I see, security chip security does not depend on itself, but also has adequate protection to the MCU, if security chip and MCU was off, not that it made

CodePudding user response:

Algorithm, is put algorithm in the encryption chip protection, main chip algorithm does not lose, then the MCU crack did not effect the

CodePudding user response:

Learned, is this meaning

CodePudding user response:

If I can't see this post, before thought we would be safe as long as the encryption chip, educated

CodePudding user response:

A good plan a good product is very useful to protect the product not to be copied,

CodePudding user response:

To make chips, there is no way to copy, after all barriers in this, ha ha ha ha

CodePudding user response:

Can adopt the method of combination of hard and soft encryption, you can consult: ATSHA204A SSHDA - T, Atmel company's hardware encryption chip;
