一种防御差分功耗分析的ECC同种映射模型
Homogeneous Mapping Model of ECC for Preventing Differential Power Analysis
摘要
Abstract
Existing public key research is based on increasing the redundance operation of Elliptic Curve Cryptosystems (ECC) aginst Differential Power Analysis (DPA) attacks,it causes ECC efficiency low,and affects the application of ECC in computation resource-restricted devices.To reach the goals of power security and computing efficiency,this paper builds an equal-value exchange model of elliptic curves based on elliptic curve isogenious mapping theory,and designs a security method that can prevent Differential Power Analysis (DPA) from attacking ECC where does not increase computational costs of ECC,and eliminates point multiplicaiton computation and relativity of leakng power information by exchanging the experssion of elliptic curves point multiplicaiton.Efficiency and security assess results show that the method does not increase computational costs of ECC,and can resisit DPA attacks.关键词
