基于奇系数 Comb 的椭圆曲线密码抗功耗攻击方案
RESISTING POWER ANALYSIS ATTACKS SCHEME FOR ELLIPSE CURVE CRYPTOGRAPHY BASED ON ODD-ONLY Comb METHOD
摘要
Abstract
The contradictions between efficiency and security lies in the cryptographic chips with limited resource when resisting power analysis attacks.In light of this,we coded the scalar with the odd-only comb algorithm and then converted the ellipse curve scalar multiplication operation to a group of small scalar multiplication operations in combination with the pre-computation table,and utilised the mask technology to exert power analysis attacks resistance,through these we presented an odd-only Comb-based resisting power analysis attacks scheme for ellipse curve cryptography.Performance analysis result of the algorithm showed that compared with traditional resisting power attack scheme,the proposed scheme could resist the simple power analysis attack,the differential power analysis attack,the zero-value register mask technology power attack and the zero-value point power analysis attack.Besides,it also had more efficient operation efficiency in the circumstance of keeping the storage space and main loop operation load basically unchanged,and had better practical applied value in a variety of application systems with limited resource.关键词
