[−][src]Struct tari_crypto::musig::JointKey
The JointKey is a modified public key used in Signature aggregation schemes like MuSig which is not susceptible to Rogue Key attacks.
A joint key is calculated from n participants by having each of them calculate: $$ L = H(P_1 || P_2 || \dots || P_n) X = \sum H(L || P_i)P_i X_i = k_i H(L || P_i).G $$ Concrete implementations of JointKey will also need to implement the MultiScalarMul trait, which allows them to provide implementation-specific optimisations for dot-product operations.

K: SecretKey,
P: PublicKey<K = K>,
pub fn index_of(&self, pubkey: &P) -> Result<usize, MuSigError>[src]
Return the index of the given key in the joint key participants list. If the key isn't in the list, returns
Err(ParticipantNotFound)
