When used with traditional, PKI-based authentication, TLS-based applications are generally safe from unknown key-share attacks. DNS-based Authentication of Named Entities (DANE), however, proposes that applications perform a different set of checks as part of authenticating a TLS connection. As a result, DANE as currently specified is likely to lead to unknown key-share attacks when clients support DANE for authentication. We describe these risks and some simple mitigations.}, }
