Nowadays RSA using Chinese Remainder Theorem (CRT) is widely used in practical applications. However there is a very powerful attack against it with a fault injection during one of its exponentiations. Many countermeasures were proposed but almost all of them are proven to be insecure.

WebAug 16, 2024 · The RSA fault attack basically focuses on a fault occurring in the generation of the signature using RSA-CRT (Chinese Remainder Theory). RSA and … WebIn many applications of RSA, d is chosen to be small. This was cryptanalyzed by Wiener in 1990 who showed that RSA is insecure if d < N 0.25. As an alternative, Quisquater and Couvreur proposed the CRT-RSA scheme in the decryption phase, where d_p = d \pmod { (p - 1)} and d_q = d \pmod { (q - 1)} are chosen significantly smaller than p and q.
