uh_huh the everybody's yep we have a great slides um so every day it's
00:00:07
if you use multiple computing devices which can include mobiles desktops or even servers
00:00:15
each of the that was that you see your on screen
00:00:18
represents of speculative execution vulnerability that has been discovered since twenty eighty
00:00:24
of special note are spectra knelt down but you might have heard off as well
00:00:28
as model spectre which isn't that that we worked on here at e. p. f. l.
00:00:33
so let's take a look into how these speculative execution vulnerabilities exposed
00:00:38
just suppose you have a recipe program is a lot like a
00:00:41
recipe and a chef does not necessarily perform all the steps in order
00:00:46
for example if the first asked for onions and there are no
00:00:50
onions in though in the pantry a chef can order these onions
00:00:55
while waiting for these onions is normally a chef will go ahead and perform later steps
00:01:00
in this case the chef can go ahead and cry in the collective which is necessary for the secret sauce
00:01:07
there are some side effects to this specifically for the car like you have a smell which remains
00:01:13
and that is how willie secrets so that's to construct look into what a typical attacked looks like in the first step
00:01:21
uh attacker forces of victim to be speculate and perform some secret dependent work
00:01:26
so what the victim is doing the secret dependent work in other we're what's making the garlic based
00:01:32
you it should be some smell with the attacker can come in and read to figure out what the secrets were
00:01:38
so in our in my research i'm trying to stop the attacker at each of these steps
00:01:43
forced i'm trying to see an improvement miss speculation on a victim
00:01:48
and if not can we make sure that the victim does not create if any secret depend traces
00:01:54
the final step of our defence you're trying to make sure that an attacker is unable to read
00:01:59
these traces and in fact the the secrets thank
