The base SHAKEN specification provides replay-detection mechanisms to identify cases where a malicious entity attempts to masquerade as another user by replaying parts of a legitimate INVITE request. However, these mechanisms don't cover cases where the INVITE is replayed within the short Date freshness window. This technical report describes how the mechanisms defined by [draft-ietf-stir-passport-divert] can be integrated within the SHAKEN framework to close this replay attack window.
