Abstract

In various embodiments, a circuit arrangement is provided. The circuit arrangement may include a detection circuit, which is designed to detect light attacks on the circuit arrangement; a processing circuit, which is designed to initiate a current flow through a line for each light attack detected by the detection circuit; and a control circuit, which is designed to enable functioning of a component of the circuit arrangement depending on the conducting state of the line.
