  The IoT consists of a lot of devices such as embedded systems, wireless
sensor nodes (WSNs), control systems, etc. It is essential for some of these
devices to protect information that they process and transmit. The issue is
that an adversary may steal these devices to gain a physical access to the
device. There is a variety of ways that allows to reveal cryptographic keys.
One of them are optical Fault Injection attacks. We performed successful
optical Fault Injections into different type of gates, in particular INV, NAND,
NOR, FF. In our work we concentrate on the selection of the parameters
configured by an attacker and their influence on the success of the Fault
Injections.
