IC卡芯片DES加密差分功耗分析方法
Differential Power Analysis Method for DES Encryption in IC Card Chip
摘要
Abstract
Based on the principle of Side-channel Analysis(SCA) and power leakage of IC chip,this paper analyzes the relationship of encryption process and power leakage of IC chip.According to the problem of power leakage in chip Data Encryption Stardard(DES)encryption,it brings out power diff-function Differential Power Analysis(DPA) and correlation analysis method,which are based on S-box output.It uses Inspector platform to do DPA examinations,and is succeed in cracking the key of some chip's DES encryption.Examinations results not only prove the correctness of test method,but also find the power leakage security vulnerability of traditional DES algorithm used in IC chip.关键词
