Secure Telephone Identity Revisited Out-of-Band Architecture and Use Cases
RFC 8816, “Secure Telephone Identity Revisited Out-of-Band Architecture and Use Cases”, is an Informational document published in February 2021 by E. Rescorla, J. Peterson. The canonical text is published by the RFC Editor.
Abstract
The Personal Assertion Token (PASSporT) format defines a token that can be carried by signaling protocols, including SIP, to cryptographically attest the identity of callers. However, not all telephone calls use Internet signaling protocols, and some calls use them for only part of their signaling path, while some cannot reliably deliver SIP header fields end-to-end. This document describes use cases that require the delivery of PASSporT objects outside of the signaling path, and defines architectures and semantics to provide this functionality.
