Schnorr sigs rely so heavily on the masking provided by a random nonce. There are so many easy ways to introduce bias (hash + modulo, for example).
Even 2 bits of bias can result in serious attacks: https://ecc2017.cs.ru.nl/slides/ecc2017-tibouchi.pdf Maybe pairing based sigs - which are slower - might be both more flexible, and better suited to secure implemetnations? _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
