A mathematical analysis is necessary to ensure the security of the cipher. In this thesis, I develop several new contributions for the analysis of block ciphers. I determine cryptographic properties of several special cryptographically interesting mappings like almost perfect nonlinear functions. I also give some new results both on the resistance of functions against differential-linear attacks as well as on the efficiency of implementation of certain block ciphers.<eng> vorgelegt von Lukas Kölsch GutachterInnen: Gohar Kyureghyan (Universität Rostock) ; Petr Lisonek (Simon Fraser University Vancouver) ; Ferruh Özbudak (Middle East Technical University Ankara) Dissertation Universität Rostock 2020 510 512.2 510 SK 170 http://purl.uni-rostock.de/rosdok/id00002900 https://doi.org/10.18453/rosdok_id00002900 https://nbn-resolving.org/urn:nbn:de:gbv:28-rosdok_id00002900-8 https://d-nb.info/1293662305/34 Mathematical aspects of the design and security of block ciphers--(DE-627)1745274111 urn:nbn:de:gbv:28-rosdok_id00002900-8 doi: 10.18453/rosdok_id00002900 oclc: 1231554466 ppn: (DE-627)174475358X
