Practical Aspects of Physical Attacks

As physical attacks focus on implementations running on real-world devices, there are many practical aspects one needs to consider. When developing attacks and countermeasures, we often work with simplified models of those devices. However, once we move from theoretical assumptions to practice, there might appear deviations stemming from process variations, measurement errors, and various noise sources that are not easy to determine. Apart from that, this chapter will also focus on industrial standards that relate to hardware security.
