</div>
<div>
<p class=MsoNormal>The idea is create something to measure the traffic entropy.
Most of<br>
ddos attacks change (decrease) the entropy of certain traffic.<o:p></o:p></p>

<p class=MsoNormal><br>
I will try to explain the idea behind the algorithm...<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Suppose we have 3 complex strings: X, Y and Z<br>
So... if we can calculate the complexity for each string using some fomula
C(x),<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>for a random/very complex string we have : C(X) + C(Y)
+ C(Z) < C(XYZ) <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>in other words .. if you have 3 complex things (C(x) C(y)
c(z)) .. and concatenate them ... you will have something much more complex
(C(XYZ))<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>make sense ?<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><br>
This is how the algorithm works for ddos detection... measuring a normal
traffic in a port number .. we will see a lot of random payloads... and during
an attack.. it will change (if the attacker does not random the payload).<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>So.. for a normal traffic:<o:p></o:p></p>
</div>

<p class=MsoNormal>Complexity_of(Packet1) + Complexity_of(Packet2) +
Complexity_of(PacketN) =< All_complexity(Packet1+Packet2+PacketN)<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>and for a ddos:<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Complexity_of(Packet1) + Complexity_of(Packet2) +
Complexity_of(PacketN) > All_complexity(Packet1+Packet2+PacketN)<o:p></o:p></p>
