| Jan 30, 2020 at 12:24 | comment | added | lovesh | There is a somewhat related work called Pixel (eprint.iacr.org/2019/514.pdf) where you can do forward secure multi-signatures or threshold signatures (using similar ideas as for BLS sigs). However, to create a (multi or threshold)signature, all parties have to use the key at the same index in the derivation chain | |
| Jan 30, 2020 at 9:19 | comment | added | Bernd Strehl | Yes, that's why the question is, if there is a KDF, whose key derivates can be used for a threshold signature without additional constructions. | |
| Jan 29, 2020 at 16:36 | comment | added | shumy | Yes, however, constructing a threshold signature is more complex than just interpolating all the $sig_{i}$ results. | |
| Jan 29, 2020 at 16:20 | comment | added | Bernd Strehl | I want to know if they can be used together. | |
| Jan 29, 2020 at 15:31 | comment | added | shumy | The key generation and distribution vs threshold signatures are two different problems. What do you want to solve exactly? | |
