AES密码芯片的多比特DEMA攻击实现

摘要

多比特DEMA攻击是一种有效的密码算法旁道攻击方法。在分析汉明重量模型和DEMA攻击原理的基础上，提出了一种多比特DEMA尖峰模拟分析方法，并以AES算法为例进行了模拟分析，最后针对AES算法进行了多比特DEMA攻击实现，攻击结果验证了DEMA尖峰模拟分析方法的有效性。%Multi-bits DEMA attack is an effective side-channel attack method on cryptographic algorithm. Based on the analysis of the Hamming-weight model and the principle of DEMA, the paper proposes a method of multi-bits DEMA peak simulation analysis. Then the paper makes simulation analysis and realizes the multi-bits DEMA attack on the AES algorithm. The result proves the effective of the DEMA peak simulation analysis.
