The Problem Let’s say you have a compiled binary, but you […]https://miscreants.github.io/blog.trailofbits.com/2018/08/14/fault-analysis-on-rsa-signing/Tue, 14 Aug 2018 12:39:52 -0400https://miscreants.github.io/blog.trailofbits.com/2018/08/14/fault-analysis-on-rsa-signing/This spring and summer, as an intern at Trail of Bits, I researched modeling fault attacks on RSA signatures. I looked at an optimization of RSA signing that uses the Chinese Remainder Theorem (CRT) and induced calculation faults that reveal private keys. I analyzed fault attacks at a low level rather than in […]
