Standards-based STIR/SHAKEN

What is a standards-compliant STIR/SHAKEN system, and why does it matter? Here’s a quick overview.

Legislation and regulations

The TRACED Act directs the FCC to issue rules for the deployment of STIR/SHAKEN by voice service providers in the U.S.

The FCC issued the following reports and orders:

Standards-based STIR/SHAKEN

Industry standards cited in FCC orders

The FCC reports and orders cite industry standards documents to specify what the STIR/SHAKEN framework is:

  • ATIS-1000074. ATIS Standard of Signature-based Handling of Asserted Information using toKENS (SHAKEN)
  • ATIS-1000080. ATIS Standard on Signature-based Handling of Asserted information using toKENs (SHAKEN): Governance Model and Certificate Management

So that’s it? These two documents cover the standards?

Not exactly.

Industry standards refer to and build upon previous standards. Within each of the documents listed above, there are lists of normative references to other standards documents. The latest version of ATIS-1000074 lists eleven standards documents as normative references, and the latest version of ATIS-1000080 lists twenty-one normative references. (Many references appear in both.) The two standards documents listed by the FCC inherit many other standards.

The importance of standards

So, why does it matter? Because by following standards, different STIR/SHAKEN systems can interoperate with each other.

Other standards documents

From two documents we’ve uncovered many other standards that they build upon. But there are other STIR/SHAKEN standards that we haven’t mentioned yet. For example, ATIS-1000085 describes support for a “div” PASSporT used for diversion.

There are also standards documents in development. These documents describe exciting new capabilities for STIR/SHAKEN, including:

  • Delegate certificates to support customer-of-customer attestation scenarios
  • Rich Call Data to support additional caller information
  • Out-of-Band SHAKEN to support another way to transmit PASSporTs
  • Toll-Free Calls in the SHAKEN framework to support that

Each of these standards document includes normative references that the document inherits. This enables each document to be much more concise and focus on what’s new for that topic.
