Mechanism for Initial Cross-Border Signature-based Handling of Asserted information using toKENs (SHAKEN)-(ATIS-1000087)

This document provides telephone service providers with a framework and guidance on how to use Secure
Telephone Identity (STI) technologies on IP-based service provider voice networks (also to be referred to as Voice
over Internet Protocol [VoIP] networks) in scenarios where a call originates in one country and terminates in a
different country. The primary focus of this document is to detail how the trust environment created by Signaturebased
Handling of Asserted information using toKENs (SHAKEN) in a single country can be extended to include
other countries. This document does not require any changes to the existing SHAKEN specifications but does
identify new interfaces and functions to exchange information between countries.
