btw,
eagle.rom.addr.v6.ld
how this hw function to be use?

aes_decrypt = 0x400092d4
aes_decrypt_deinit = 0x400092e4
aes_decrypt_init = 0x40008ea4
aes_unwrap = 0x40009410

_rom_store = 0x4000e388
_rom_store_table = 0x4000e328

there are MD5, SHA and more availabel...

we have more protection availabel!?
are there api function ;-) ;-) ;-)

;-)

best wishes
rudi ;-)

thks for your reply. As far as i know, that´s only a partial solution, since contents of flash memory can still be read and programmed into another ESP8266 module.

Am i wrong here?


Rgds,

After boot, check chip id and the key value , run while(1) if not match.

If you wish to make it something that it is not (eg. secure), then your most probable bet is to destroy the UART pins. Might even do it with electricity.

For updating mechanisms, you can come up with a wireless and encrypted method.

I'm also interested in this topic. There is the possibility of encrypting the contents of flash memory. I have asked this question before to people at Espressif with no luck.
Hope we can all push harder to get this feature up and running. It´s really important for commercial applications.

Greetings,


Horacio

Hi,

We developed some application for ESP8266 directly flashed via UART. Problem is anybody can readout our code out via UART. Is there any solution to protect our code inside ESP8266?
Thx for possible help.


Physically kill the UART pins.
