Fault attack on rsa-crt
WebQuestion: 1 Fault attacks against RSA signatures 1. Implement the signature generation algorithm using the Chinese Remainder Theorem (CRT) using the Sage library. More precisely, to compute s=mdmodN, compute sp=smodp=mdmodp−1modp and sq=smodq=mdmodq−1modq Recover smodN from sp and sq using the CRT. 2. WebRSA digital signatures based on the Chinese Remainder Theorem (CRT) are subject to power and fault attacks. In particular, modular exponentiation and CRT recombination are prone to both attacks. However, earlier countermeasures are susceptible to the ...
