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. %L 510 %9 theses %9 Text %9 Hochschulschrift %R 10.18453/rosdok_id00002900 %U http://purl.uni-rostock.de/rosdok/id00002900 %U https://nbn-resolving.org/urn:nbn:de:gbv:28-rosdok_id00002900-8 %U https://d-nb.info/1293662305/34 %U https://doi.org/10.18453/rosdok_id00002900
