摘要
分析了电磁信息泄漏的机理,介绍了电磁信息泄漏的发展历史和趋势,阐述了电磁信息泄漏的基本概念和主要研究内容。针对P89C668单片机实现的DES密码系统,采用差分电磁分析的方法对其进行密码破译实验,获得了DES第16轮48 bit子密钥。
The mechanism of EM information leakage is analyzed. Then of this technique are expounded, and concept of information leakage the development status and trend and content of research are discussed. Finally,with the cryptographic system realized by P89C668 microcomputers and encrypted with DES,the 48-bit sub-key of the round 16 of DES is obtained by Differential Electromagnetic Analysis（ DEMA）.
