1. An integrated circuit, comprising:
- an integrity sensor; and
a checking unit;
wherein the integrity sensor is based on a physical, unclonable function, wherein the integrity sensor is configured to receive a challenge signal and to use the challenge signal to send a response signal to the checking unit, and wherein the response signal is produced using the physical unclonable function; and
wherein the checking unit is configured to receive the response signal and to use the response signal to determine first information about degradation of the integrated circuit.

Abstract
An integrated circuit configured for malfunction detection includes an integrity sensor and a test unit. The integrity sensor is based on a physical, unclonable function. The test unit is configured to send a challenge signal to the integrity sensor, and to determine information about a degradation of the integrated circuit. The information is based on a response signal subsequently generated by the physical, unclonable function and sent by the integrity sensor to the test unit.
