针对侧信道信息辅助的基于持久性故障的碰撞攻击的改进
Improvement on Side-Channel Information Assisted Persistent Fault-Based Collision Attacks
摘要
Abstract
Zheng et al.utilize side-channel information in persistent fault-based collision attacks to break countermeasures against fault attacks,such as redundancy detection.They implemented the protected AES algorithm on a smart card and validated the analysis method.Nevertheless,the more considerable noise in the power consumption traces collected from the algorithm implemented on the FPGA prevents the attack.This study denoises by the singular spectrum analysis and revises the statistical method for determining collision plaintext bytes.Consequently,the key of AES-128 secured by an algorithm-level countermeasure implemented on FPGAs is successfully recovered.Furthermore,for SM4 implementation protected by a round-level countermeasure,the chosen plaintext method is optimized by exploring the properties of the Feistel structure and the XOR operation in the round function.As a result,the time complexity of the plaintext selection process is reduced to O(218),and the analysis greatly speeds up.关键词
