Chris deals with military secure devices. He is working on a closed source device and he is analyzing its power consumption. Chris is passionated and wants to work from home.
As such he decided to run a server on
aes-leakage.crypto.w3challs.com:7779 that takes an input, sends it to the board, records the traces from an oscilloscope, and sends them back.
Each byte in the trace represents the power consumption (y axis) for a given time (x axis, position in the output).
The trace is encoded using unsigned 8-bits values.
Can you help Chris in getting the embedded key? Submit it as a lowercase 32-hexdigits string to solve this challenge.
