How to secure C code?

#1

If my understanding is correct it is possible to secure the C code uploaded to a CubeCell via encryption. Is there anywhere a step by step sample how to do it?

Sorry, in case I oversaw it in the docs. Nevertheless, a link would be great…

Thanks a lot for your advice and time…

Hi,

Don’t worry about this problem. Our cubecell have multiple encryption technologies.

Each cubecell device is bound to the MAC address of its hardware. If you have a same hardware device(but not make by heltec)with one cubecell and you also read the flash(to get the binary file)from your cubecell device.

Then you burn this binary file to another device. It will not useful because of the multiple encryption technologies.

So if I understand it correctly there is nothing from our side to do. It does happen automated as part of the upload. Is this correct?

@jasonXu - Just want to be sure I do understand right.

Yes, the anwser is Yes.

Thank’s a lot for the confirmation.

Hello

I’m using Lora, not LoraWan. Is there a library to use for aes encryption?

Hi Jason,

I realise this is quite an old post but… I understand detailed encryption methods are important to not disclose publicly, but are you able to provide any more general information about the encryption approaches Heltec uses to secure the code? Also does this apply to the new CC-AB01 v2 boards?

Many thanks
