Abstract (en)

[origin: WO2014012701A1] In order to reliably detect a malfunction of an IC, an integrated circuit (IC) comprises an integrity sensor (4) and a test unit (3). The integrity sensor (4) is based on a physical unclonable function (PUF) (24). The test unit (3) is designed to send a challenge signal (C) to the integrity sensor (4) and to determine a piece of information about a degradation of the integrated circuit (IC) on the basis of a response signal (R) subsequently generated by the physical unclonable function (24) and sent by the integrity sensor (4) to the test unit (3).
