Crate cggmp21_keygen::key_share
source · Expand description
Key share of Threshold Signature Scheme (TSS)
TSS protocols often share the same structure of key share. Having a separate crate with definition of the key share struct help reusing the code, keeping different implementations compatible and interopable.
The crate provides DirtyCoreKeyShare
that contains data such as: secret share, other signers commitments,
public key and etc.
DirtyCoreKeyShare
may contain any data, not necessarily consistent. TSS protocol implementations typically
don’t want to handle inconsistent key shares and would rather assume that it’s valid. Valid<T>
is a type-guard stating that the value T
it holds was validated. So, Valid<DirtyCoreKeyShare>
(or
CoreKeyShare
type alias) can be used to express that only valid key shares are accepted.
