You will need to use both of these to complete this Example. We recommend opening two separate instances

of Arduino, this way you can setup each one with its own com port for uploading and serial terminal.

Hardware hookup

For Example 4, you will need to setup two Artemis boards with two co-processors, and connect a couple jumper

wires between them. Using the Artemis Redboard, there is no soldering required for this setup.

Connect both of your Artemis boards to your computer using USB-C cables. Connect a Cryptographic Co-

processor to each board using a Qwiic cable.

connect GND to GND for good measure.

Fritzing diagram for hardware connections.

Note, both Alice and Bob need their own co-processor. So you're complete setup should look something like this:

Hardware connections.

Code setup

We will need to copy/paste Alice's public Key into the top of Bob's Sketch. First upload Alice's sketch to Alice, then

watch her terminal at 115200. Copy her public key.

Now go over to Bob's sketch. Delete the place holder "blank" public key at the top, and paste in Alice's public key.

Upload Bob's sketch to Bob.

message to Bob. Watch Bob's terminal. He will receive the message and verify it.
