一种针对DES密码芯片的M-DEMA攻击方法
M-DEMA Attack Method for DES Code Chip
摘要
Abstract
In order to research for secret information leakage by electromagnetic signal, use multiple-bit differential electromagnetic analysis (M-DEMA) is applied to side channel attacks (SCA) in code chip. Based on analysis the principle of direct electromagnetic radiations for complementary metal-oxide-semiconductor (CMOS) circuit. A near-field electromagnetism radiations signals acquisition and analysis platform of DES microcontroller (AT89C52) code system is designed and constructed. Introduce M-DEMA attack method in detail, realize the attack test and test results analysis. The experimental results show that the method is effective, compared with conventional DEMA method, this method can use less traces successfully extract the secret key of DES cryptographic device, and can improve the success rate of attacks.关键词
