We'll only be able to change the LAST TWO bytes, everything else will be too slow. So change the input plaintext to <code>00 00 00 00 00 00 00 00 00 00 00 00 00 00 80 00 And </code> and you can see the power trace change drastically, as below:

Finally, let's flip another bit. Change the input plaintext as followsto <code> 00 00 00 00 00 00 00 00 00 00 00 00 00 00 80 10</code>, such that bit #4 in the final bit is set HIGH. We can plot the two power traces on top of each other, and you see that they are differing at a specific point in time:
