| Abstract: | DEMA is a side channel attacks which used to access the key of DES efficiently. According to the electromagnetic leakage principle of CMOS chips, a platform of DEMA for DES has been constructed; differential attacks and the principle of radiated electromagnetic analysis was introduced. Based on virtual instrument technology , the radiated electromagnetic was measured by magnetic probe and supplied good signal. A electromagnetic attack with 1000 samples has been realized with optimization algorithm for multi-core computer. All progress only took half an hour. |
