AbortKind

dkls23::protocols

Enum AbortKind 

Source 
pub enum AbortKind {
    Recoverable,
    BanCounterparty(PartyIndex),
}
Expand description

Classifies the severity and required response for an abort.

The DKLs23 protocol reuses base OT correlations across signing sessions. If the COTe consistency check fails, information about this reused state is leaked. The paper mandates that the offending counterparty must be permanently banned from all future sessions. Failure to do so enables a key extraction attack over multiple sessions.

Variants§

§

Recoverable

The protocol failed but can be retried safely. No long-term state was compromised.

§

BanCounterparty(PartyIndex)

The identified counterparty cheated in a way that leaks information about reusable OT state. This party MUST be permanently excluded from all future signing and refresh sessions. Continuing to interact with this party enables private key extraction.
