Help!Threshold Signing using Charm #219

Open songlinjian opened 5 years ago

songlinjian commented 5 years ago

I got to know Charm project via Honey Badger paper. The author used Charm to implement a scheme of threshold signatures*. I would like do the similar scheme both for RSA and ECC.

Before I got to know Charm, I was told that BLS is also a tool fitting my scenario. So I’m writing to ask : 1) what’s the difference of Charm and BLS, also PBC library. 2) Because I’m not a crypto people, how should I start using Charm to build a scheme. 3) is there any existing scheme I can used directly for threshold signing?

Thanks in advance.
