Chosen Message Side-Channel Attacks Against Elliptic Curve Cryptosystems
摘要
Abstract
Base on the safety study of side-channel attacks of Elliptic curve cryptosystems (ECC) algorithm ,a novel chosen-message side-channel analysis attacks for public-key cryptosystems was proposed based on scalar multiplications such as ECC .Using the special characteristics of scalar multiplications in the finite field ,when input point P was close to the horizontal axis or the vertical axis ,noticeable side-channel variations were gen-erated in continuous point doubling and point addition operations .This chosen plaintext can be exploited for simple power analysis(SPA)attacks against ECC ,analyzing whether point doubling or point addition opera-tions was obtained .Thereby ,in the binary algorithms (including both for left-to-right and right-to-left meth-ods) ,the key code can be obtained ,the ECC algorithm code will be cracked effectively .关键词
