Struct dkg_gadget::gossip_engine::HandshakeMessage
source · pub struct HandshakeMessage {
pub authority_id: AuthorityId,
pub peer_id: Vec<u8>,
pub signature: AuthoritySignature,
}
Expand description
A Handshake message that is sent when a peer connects to us, to verify that the peer Id (which is the sender) is the owner of the authority id. This is used to prevent a malicious peer from impersonating another authority. Notes:
- The peer id is the id of the peer that sent the handshake message.
- The authority id is the id of the authority that the peer claims to be.
- The signature is the signature of (peer id, authority id) by the authority id.
- The signature is used to verify that the authority id is the owner of the peer id.
Fields§
§peer_id: Vec<u8>
§signature: AuthoritySignature
Implementations§
source§impl HandshakeMessage
impl HandshakeMessage
sourcepub fn try_new(
keystore: &DKGKeystore,
peer_id: PeerId
) -> Result<Self, DKGError>
pub fn try_new( keystore: &DKGKeystore, peer_id: PeerId ) -> Result<Self, DKGError>
Create a new handshake message.
This will sign the peer id and authority id with the authority id. Returns an error if the authority id does not have a corresponding private key in the keystore.
