Description
One of your friends tells you that a 1024-bit EEPROM connected to his Arduino is an extremely secure way to store his secrets, since the protocol used is “obfuscated” and “low level” according to him, “not like the USB which is hotplug and that you can plug directly into any OS!”.
To prove him that he is wrong, you use your logic analyzer to sniff the communication between the Arduino and the EEPROM when he types his secret.
Can you recover his secret with softwares like Sigrok and gtkwave?
