Fault injection attack is a serious threat to the security of embedded devices. In fault injection attacks,
an adversary applies physical stress to a target embedded device, causes a computational fault, and
exploits the faulty computational result to break the system’s security. A laser is an effective way of
applying such physical stress, and laser fault injection attacks have been scrutinized over the last decade.
This paper, which explains and describes laser fault injection attacks to researchers and practitioners in
the laser field, covers the following three main topics: (i) general physical attacks on embedded systems,
(ii) the mechanism through which a laser injection causes a computational fault, and (iii) sensor-based
countermeasures that detect an attempt of fault injection attacks.
