Neustar to accelerate adoption of STIR/SHAKEN caller ID authentication standards

Neustar®, Inc., a global information services company and provider of identity resolution, has been approved as an initial Secure Telephone Identity Certification Authority (STI-CA), the company said.

As an STI-CA, Neustar is authorized to issue the digital certificates used by communication service providers to authenticate and verify telephone calls — a key element in the fight against illegal caller ID spoofing.

The Federal Communications Commission (FCC) has long been encouraging the telecommunications industry to address the scourge of spoofed calls, and the industry´s response has resulted in the development of the STIR/SHAKEN standards and framework.

STIR (Secure Telephony Identity Revisited) is a set of technical standards developed by the Internet Engineering Task Force to provide a means to certify the identity of originating calls. SHAKEN (Signature-based Handling of Asserted information using toKENs) is a framework developed by the Alliance of Telecommunications Industry Solutions (ATIS) that is focused on the implementation of STIR within IP-based service provider networks.

The FCC has directed voice service providers to implement robust call authentication using STIR/SHAKEN by the end of 2019. To help providers meet this target, the STI-Policy Administrator (STI-PA) has overseen the approval of a limited number of certification authorities to join the STI ecosystem at go-live, scheduled for Dec. 16.
