一种带掩码AES算法的高阶差分功耗分析攻击方案
A High-order Differential Power Analysis Attack Scheme with Masked AES Algorithm
摘要
Abstract
In view of the serious threats that power analysis attacks causes on the security of the cipher chip,based on the in-depth study of masked technology,this paper proposes a High Order Differential Power Analysis (HODPA) scheme which attacks the fixed value mask through the use of preprocessing function.By using the joint distribution of the two points on the power curve,this method successfully bypasses the mask's protection of the system.It develops a side channel attack platform based on MEGA16 and carries out the experimental verification.Experimental result shows that,without knowing the specific masked value,the ordinary first order DPA cannot recover the correct key,but HODPA only needs about 500 power curves to get the correct key,and discrimination between correct key and wrong keys is high,fully proves the validity and practicability of the scheme.关键词
