Zeng Qingguang · Computer Engineering and Applications Journal · 2010
Based on the principle of power leakage of CMOS chips,a simple and efficient power consumption model is presented,and a power analysis attack scheme for DES encryption algorithm is devised,and then the 48-subkey of DES encryption algorithm is cracked on this self-developed power analysis simulator.The result shows that DES encrypted systems without any extra protective measures have potential security problems.The simulator provides a simple,intuitionistic,fast and effective evaluation platform for the research of power analysis methods and anti-power analysis.Finally,the possible anti-power methods are analyzed.
