Combatting Caller ID Spoofing: A Deep Dive into STIR/SHAKEN and PeeringHub's Role

In an era where robocalls and Caller ID spoofing have become ubiquitous, the battle to protect consumers from malicious calls is more crucial than ever. The Federal Communications Commission (FCC) has mandated the implementation of STIR/SHAKEN, a framework designed to authenticate and verify caller identity, providing a critical defense against illegal robocalls and fraud. This article explores the intricacies of STIR/SHAKEN, its importance, and the key role played by PeeringHub.io in this ongoing fight.

Understanding STIR/SHAKEN: A Comprehensive Overview

STIR/SHAKEN, an acronym for Secure Telephone Identity Revisited and Signature-based Handling of Asserted Information Using Tokens, represents a framework of technical protocols and procedures. It authenticates the caller's identity at the originating service provider and enables the recipient's service provider to verify Caller ID, effectively reducing the risk of fraudulent robocalls and Caller ID spoofing.

STIR, or Secure Telephony Identity Revisited, is the protocol developed by the Internet Engineering Task Force (IETF) to provide a digital signature for the calling party's credentials. SHAKEN, or Secure Handling of Asserted Information Using Tokens, is the applied framework that deploys STIR technology within carrier networks.

The STIR/SHAKEN Process Unveiled: How It Works

STIR/SHAKEN employs key cryptography standards to authenticate IP phone calls. The process involves eight distinct steps:

1. Receiving SIP Invite and Assigning Attestation Level
2. Assigning Attestation Level
3. Adding Certificate Information to SIP Identity Header
4. Receiving SIP Invite with Augmented Identity Header
5. Sending SIP Identity Header Information for Verification
6. Validating Certificate Information
7. Returning SIP Identity Header Information to Terminating Provider
8. Intended Recipient Receives the Call

This highly technical process adds a robust layer of defense against bad actors with malicious intentions, ensuring the authenticity of caller identity.

The Importance of STIR/SHAKEN: Reducing Fraud, Robocalls, and Restoring Trust

STIR/SHAKEN holds significant importance in the telecommunications landscape, offering several benefits:

1. Minimizing Potential Fraud: With the rise in fraudulent activities, STIR/SHAKEN acts as a safeguard, protecting consumers from potential financial losses.
2. Reducing Robocalls: Specifically designed to decrease the number of robocalls using spoofed Caller ID, STIR/SHAKEN enhances legitimate business productivity.
3. Protecting Business Reputation: Service providers benefit from STIR/SHAKEN by offering safer and more controlled services, contributing to a trustworthy environment.

While STIR/SHAKEN is a substantial step in reducing malicious calls, it doesn't provide a foolproof solution. Service providers should complement it with personalized call screening tools and call blocking lists for enhanced security.
