Public Key Info

Contains public information about the TSS key, including shared public key, commitments to secret shares and etc.

Fields

curve: CurveName<E>

Guard that ensures curve consistency for deseraization

shared_public_key: NonZero<Point<E>>

Public key corresponding to shared secret key. Corresponds to X in paper.

public_shares: Vec<NonZero<Point<E>>>

Public shares of all signers sharing the key

public_shares[i] corresponds to public share (or public commitment) of $\ith$ party.

vss_setup: Option<VssSetup<E>>

Verifiable secret sharing setup, present if key was generated using VSS scheme

chain_code: Option<ChainCode>

Available on crate feature hd-wallets only.

Chain code associated with the key, if HD wallets support was enabled

Implementations

impl<E: Curve> DirtyKeyInfo<E>

pub fn share_preimage(&self, j: u16) -> Option<NonZero<Scalar<E>>>

Returns share preimage associated with j-th signer

• For additive shares, share preimage is defined as j+1
• For VSS-shares, share preimage is scalar $I_j$ such that $x_j = F(I_j)$ where $F(x)$ is polynomial co-shared by the signers and $x_j$ is secret share of j-th signer

Note: if you have no idea what it is, probably you don’t need it.
