The Signature-based Handling of Asserted information using toKENs (SHAKEN) standard ?ATIS-1000074? specifies operation within the domain of a single national or regional regulatory authority - in most cases this means within a single country. This was a conscious decision by the joint Alliance for Telecommunications Industry Solutions (ATIS) and SIP Forum IP-NNI Task Force (IP-NNI TF) in order to more quickly develop a solution that explicitly addressed U.S. requirements. However, SHAKEN does not assume unique U.S. attributes, and therefore should be equally applicable to other countries. Calls that originate in one country and terminate in another country, are not explicitly addressed in the existing SHAKEN standard. This document provides a mechanism to extend the SHAKEN trust environment to include more than one country without requiring service providers to make changes to their current standard SHAKEN interfaces.
