In our approach, the implementation serves as its own watermark that is recorded through its fault effects. There is no additional code for the watermark. A simulator that maps the fault injections to the executed instructions aids an automated characterization of program code. We provide a proof-of-concept implementation of our watermarking approach using an 8-bit ATMega163 microcontroller and several assembly implementations of AES encryption. The results show that our method is well-suited for detection of identical software copies. In addition, our method shows robust performance in detection of software copies with a large number of added dummy instructions. %G English %Z TC 11 %Z WG 11.2 %2 https://inria.hal.science/hal-01639613/document %2 https://inria.hal.science/hal-01639613/file/421627_1_En_13_Chapter.pdf %L hal-01639613 %U https://inria.hal.science/hal-01639613 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-TC11 %~ IFIP-WISTP %~ IFIP-WG11-2 %~ IFIP-LNCS-9895
