Fault Attack on an Improved CRT-RSA Algorithm with the Modulus Chaining Method

Abstract

S. Lee, D. Choi and Y. Choi proposed an improved countermeasure algorithm of RSA cryptosystem with Chinese Remainder Theorem to prevent fault attack. In this paper, we introduce new fault attacks on their countermeasure algorithm. Our analysis shows that the attacker can obtain an erroneous signature by injecting some faults during the RSA signing… (More)
