Respectfully, your proposal does break encryption.

I am happy to spend as much time as you need reviewing in as much detail as you are comfortable with exactly how it breaks encryption, and why this is so dangerous.

[Matthew Green @matthew_d_green]

Telegram has launched a pretty intense campaign to malign Signal as insecure, with assistance from Elon Musk. The goal seems to be to get activists to switch away from encrypted Signal to mostly-unencrypted Telegram. I want to talk about this a bit. 1/

You have seen Picnic, BBQ and Banquet. Now get ready for FAEST!

TL;DR: FAEST is highly efficient AES-based digital signature scheme. It has <1ms sign/verify with 6.3KB signatures (fast mode) or 8ms sign/verify with 5KB (small mode) for 128bit security.
