- Well, it turns out that the authentication problem
may be even worse than it seems.
That's because in addition to the student remote
the same company also produces an instructor remote
that allows teachers to start and stop polling,
show and hide the poll results,
switch slides on a PowerPoint presentation,
and even select the correct quiz answer.
Now, if these devices look similar,
that's because they're actually identical under the hood.
So it's as easy to emulate this instructor remote
as it was to emulate this student remote.
And once one can do that, they can do everything
from changing the slides on the instructor's presentation
to even selecting their own quiz answers as correct,
which really emphasizes the need for a PUF
or some other hardware-based authentication mechanism.
