Jetson nano id fake

[i.nikolaev]

How can you find the unique identifier for the jetson nano?
Is it possible to change or fake it?

hello i.nikolaev,

you can dump eeprom to check the board info,
for example, $ sudo i2cdump -f -y 2 0x50

please also refer to Jetson Module EEPROM Layout for more details.
thanks

Hello, JerryChang!
Thanks for the reply.
That is, its ID cannot be changed or forged?
I want to use the board ID to create a blockchain, but I’m not sure if it’s reliable.
Do you think this is a good idea?
Thanks

hello i.nikolaev,

here’s Jetson Modules and SoCs shows the part numbers for your reference,
as you can see, that’s the board-id for Nano SOM.

may I know what’s your actual use-case,
are you looking for unique id for each of your device, MAC addresses should helps in this case.
or, you’re only looking for the board-id to recognize different Jetson modules?

Hello, JerryChang.
Thank you for your quick response.
This is for my research project on the use of blockchain in IoT.
For my case, this is not enough. The Mac address can be easily spoofed.
I thought it would be more reliable to use the ID.
Can you recommend something?
Thanks

Hi guys,
I have the same question. What is the most reliable Jetson Nano identifier?
BTW, it’s really easy to spoof a MAC address. What can Nvidia advise?

hi all,

it could using RSA key pair to have device recognize, for example, $ openssl genrsa -out rsa_priv.pem 2048
this is also a key use for fuse programming, please refer to developer guide, Secureboot for reference,
thanks
