2ae2883106 Update spec to the new DKG 2024-08-05 06:58:44 -04:00

Luke Parker
9e8e134ef7 Replace Interpolation::None with Interpolation::Constant 
Allows the MuSig DKG to keep the secret share as the original private key,
enabling deriving FROST nonces consistently regardless of the MuSig context.
 2024-08-05 06:32:37 -04:00
Luke Parker
f08faeadff Have the DKG explicitly declare how to interpolate its shares 
Removes the hack for MuSig where we multiply keys by the inverse of their
lagrange interpolation factor.

54eefbde0c Update the coordinator binary for the new DKG 
This does not yet update any tests.
 2024-08-04 04:48:12 -04:00
Luke Parker
58a435d4e9 Have set_keys take signature_participants, not removed_participants 
Now no one is removed from the DKG. Only `t` people publish the key however.

Uses a BitVec for an efficient encoding of the participants.

Luke Parker
2f564c230e Finish routing the new key gen in the processor 
Doesn't touch the tests, coordinator, nor Substrate yet.
`cargo +nightly fmt && cargo +nightly-2024-07-01 clippy --all-features -p serai-processor`
does pass.

Still a WIP.

f93bd42b99 Resolve various TODOs 
Supports recovering multiple key shares from the eVRF DKG.

Inlines two loops to save 2**16 iterations.

Adds support for creating a constant time representation of scalars < NUM_BITS.

31ac0ac299 Improve eVRF DKG 
Updates how we calculcate verification shares, improves performance when
extracting multiple sets of keys, and adds more to the test for it.

05c26d7818 Add documentation to the eVRF-based DKG 2024-08-02 00:53:23 -04:00
Luke Parker
96175e115d Inline the eVRF into the DKG library 
Due to how we're handling share encryption, we'd either need two circuits or to
dedicate this circuit to the DKG. The latter makes sense at this time.

b8472963c9 Make DKG Encryption a bit more flexible 
No longer requires the use of an EncryptionKeyMessage, and allows pre-defined
keys for encryption.

db31809708 Initial eVRF implementation 
Not quite done yet. It needs to communicate the resulting points and proofs to
extract them from the Pedersen Commitments in order to return those, and then
be tested.

880565cb81 Rust 1.80 
Preserves the fn accessors within the Monero crates so that we can use statics
in some cfgs yet not all (in order to provide support for more low-memory
devices) with the exception of `H` (which truly should be cached).
