With higher temperatures the yield of the devices rises which makes high-temperature contact materials important. The formation of titanium disilicide (TiSi2) and its properties were analyzed and optimized for the use in TEG. Depending on a direct or an indirect transformation into the C54 crystal structure the process forms a layer with a resistivity of 20-22 μΩcm. Process gases influence the resistivity and result in difference of 20 %. The growing rate of TiSi2on silicon dioxide was determined; it shows a strong dependence on the used atmosphere and temperature. A maximum overgrowing length of 30 μm was found.}}, author = {{Assion, Fabian and Schönhoff, Marcel and Hilleringmann, Ulrich}}, issn = {{0272-9172}}, journal = {{MRS Proceedings}}, keywords = {{General Engineering}}, pages = {{97--102}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Formation and Properties of TiSi2 as Contact Material for High-Temperature Thermoelectric Generators}}}, doi = {{10.1557/opl.2012.1557}}, volume = {{1490}}, year = {{2013}}, } @inproceedings{39524, author = {{Kanwar, K. and Fischer, C. and Geneiss, V. and Mager, T. and Ballhausen, U. and Hedayat, C. and Hilleringmann, Ulrich}}, booktitle = {{2012 IEEE International Conference on RFID-Technologies and Applications (RFID-TA)}}, publisher = {{IEEE}}, title = {{{Electrical characterization of rubber mixture sheets based on a coaxial probe method in combination with 3D electromagnetic simulation model}}}, doi = {{10.1109/rfid-ta.2012.6404507}}, year = {{2013}}, } @inproceedings{39511, author = {{Hangmann, Christian and Hedayat, Christian and Hilleringmann, Ulrich}}, booktitle = {{2013 IEEE 56th International Midwest Symposium on Circuits and Systems (MWSCAS)}}, publisher = {{IEEE}}, title = {{{Enhanced event-driven modeling of a CP-PLL with nonlinearities and nonidealities}}}, doi = {{10.1109/mwscas.2013.6674647}}, year = {{2013}}, } @inproceedings{39509, author = {{Hilleringmann, Ulrich and Ohms, B. and Kleine, A.}}, booktitle = {{2013 IEEE International Conference on Industrial Technology (ICIT)}}, publisher = {{IEEE}}, title = {{{Resistivity reduction in flexible dye sensitized solar cells by UV irradiation and carbon nanotubes}}}, doi = {{10.1109/icit.2013.6505770}}, year = {{2013}}, } @article{39504, author = {{Vidor, F.

An attacker with access to the target computer can reboot it or remove the RAM modules and quickly copy the RAM contents to non-volatile memory. By exploiting the known cryptographic structure of the cipher and layout of the key data in memory, in our application an AES key schedule with redundancy, the resulting memory image can be searched for sections that could correspond to decayed cryptographic keys; then, the attacker can attempt to reconstruct the original key. However, the runtime of these algorithms grows rapidly with increasing memory image size, error rate and complexity of the bit error model, which limits the practicability of the approach.In this work, we study how the algorithm for key search can be accelerated with custom computing machines.
