Understanding millions of gates


Introduction to IC reverse engineering for non-chip-reverse-engineers.
#Reverse #Engineering of #integrated #circuits is often seen as something only companies can do, as the #equipment to image the #chip is #expensive, and the HR costs to hire enough reverse #engineers to then #understand the chip even more so. This talk gives a #short #introduction on the #motivation #behind #understanding your own or someone else’s chip (as a chip manufacturing company), and why it might be important for the rest of us (not a chip manufacturing company). The #focus is on #understanding what #millions #of #logical #gates #represent, rather than the physical aspect (delayering, imaging, image processing…), because everyone can do this at home. I will introduce some #proposed #countermeasures (like logic encryption) and #explain if, how and why they fail.

The #talk will give a #general #overview of the #research #field and #explain #why #companies #are #interested #in #reverse #engineering #ICs (IP overproduction, Counterfeits, Hardware Trojans), as well as why it’s important for an end user (IC trust, chip failure). Then, I will very shortly introduce the #reverse #engineering #workflow, from #decapsulating, #delayering, #imaging, #stitching, #image #processing and then come to the focus: #netlist #abstraction. The idea is to show some #methods which are #currently #used #in #research to #understand #what #netlists #represent. Some #theory will be #explained (#circuit #design, #formal #verification of #circuits, #graph #theory…), but I want to keep this to a #minimum. Finally, I will show some #current #ideas on #how #to #make #reverse #engineering #difficult, as well as #some #attacks on these ideas. The talk does not give insights into how large companies do reverse engineering (i.e. #throw #money #at #the #problem), but rather #show #the #research #side #of #things, with some of the methods published in the last couple of years, which is #something #everyone can do at home.

Frage an die #Elektrotechniker und Fachleute rund um das Thema #Akku:
Ist das nicht ein wenig gefährlich einen Akku Pouch so zu deformieren?

Question to the #electrical #engineers and specialists around the topic #battery:
Isn't that a little dangerous to deform a battery pouch like that?

I forgot to take the Kindle out of the car last winter and it got frosty. Since then the battery capacity has gone down mercilessly. Meanwhile it has become useless and I would like to replace it. But to deform the battery in such a way ... that seems a bit dangerous to me.

Any suggestions? Do or don´t? No risk no fun? Or drop the shit complete?
