- rdtsc 1y ago> Both Kris and Armando have PhDs in cryptography. The issues here are a lot more subtle than that wiki article makes it seem. That's sort of make it look worse then, doesn't it? The main issue isn't that subtle. Even the wikipedia mentions it: > points should always be validated before being relied upon for any computation. Moreover the paper https://eprint.iacr.org/2015/565.pdf https://eprint.iacr.org/2015/565.pdf also mentions a few times: > Algorithm 2 assumes that the input point P is in E(Fp2)[N], i.e., has been validated according to Appendix A Appendix A: > The main scalar multiplication routine (in Algorithm 2) assumes that the input point lies in E(Fp2 )[N]. However, since we have #E(Fp2) = 392 · N, and in light of small subgroup attacks [39] that can be carried out in certain scenarios, here we briefly mention how our software enables the assertion...
- commandersaki 1y agoYou realise experts at cryptography, even implementation, are fallible right? Case in point: https://www.daemonology.net/blog/2011-01-18-tarsnap-critical-security-bug.html https://www.daemonology.net/blog/2011-01-18-tarsnap-critical... Not saying the same situation either; obviously Colin made a silly mistake while refactoring. We don't actually know the issue with these implementors, but again I ask, with having actual professionals in the field, what should they have done instead of rolling their own for a primitive that doesn't exist in the language?
