The rise of robocalls has become a significant nuisance for many individuals, with millions of unwanted calls being made every day. To combat this issue, the Federal Communications Commission (FCC) has implemented a technology called Stir Shaken. But how does Stir Shaken work, and what impact does it have on the fight against robocalls? In this article, we will delve into the inner workings of Stir Shaken and explore its role in reducing unwanted calls.
Understanding the Basics of Stir Shaken
Stir Shaken is a framework of protocols and procedures designed to authenticate the source of incoming calls. The name “Stir Shaken” comes from the James Bond martini order, “shaken not stirred.” In this context, “Stir” refers to the Secure Telephony Identity Revisited (STIR) protocol, while “Shaken” refers to the Signature-based Handling of Asserted information using toKENs (SHAKEN) framework.
STIR: The Secure Telephony Identity Revisited Protocol
STIR is a protocol that enables the authentication of caller ID information. It uses digital certificates to verify the identity of the calling party, ensuring that the caller ID information is accurate and trustworthy. STIR works by assigning a unique digital certificate to each phone number, which is then used to authenticate the caller ID information.
How STIR Works
Here’s a step-by-step explanation of how STIR works:
- A caller initiates a call to a recipient.
- The caller’s phone service provider assigns a unique digital certificate to the caller’s phone number.
- The digital certificate is used to authenticate the caller ID information.
- The authenticated caller ID information is then transmitted to the recipient’s phone service provider.
- The recipient’s phone service provider verifies the authenticity of the caller ID information using the digital certificate.
SHAKEN: The Signature-based Handling of Asserted information using toKENs Framework
SHAKEN is a framework that builds upon the STIR protocol. It provides a set of procedures for phone service providers to follow when handling caller ID information. SHAKEN enables phone service providers to verify the authenticity of caller ID information and assign a level of trust to each call.
How SHAKEN Works
Here’s a step-by-step explanation of how SHAKEN works:
- A caller initiates a call to a recipient.
- The caller’s phone service provider assigns a level of trust to the call based on the authenticity of the caller ID information.
- The level of trust is then transmitted to the recipient’s phone service provider.
- The recipient’s phone service provider uses the level of trust to determine whether to block or allow the call.
The Impact of Stir Shaken on Robocalls
Stir Shaken has a significant impact on the fight against robocalls. By authenticating caller ID information and assigning a level of trust to each call, Stir Shaken makes it more difficult for robocallers to spoof caller ID information.
Reducing Spoofed Calls
Spoofed calls are a common tactic used by robocallers to trick recipients into answering their calls. By spoofing caller ID information, robocallers can make it appear as though the call is coming from a trusted source, such as a bank or government agency. Stir Shaken makes it more difficult for robocallers to spoof caller ID information, reducing the number of spoofed calls.
How Stir Shaken Reduces Spoofed Calls
Here’s a step-by-step explanation of how Stir Shaken reduces spoofed calls:
- A robocaller attempts to spoof caller ID information.
- The spoofed caller ID information is transmitted to the recipient’s phone service provider.
- The recipient’s phone service provider uses Stir Shaken to verify the authenticity of the caller ID information.
- If the caller ID information is found to be spoofed, the call is blocked or flagged as suspicious.
Improving Call Blocking
Stir Shaken also improves call blocking by enabling phone service providers to block calls that have been identified as robocalls. By assigning a level of trust to each call, Stir Shaken makes it easier for phone service providers to identify and block robocalls.
How Stir Shaken Improves Call Blocking
Here’s a step-by-step explanation of how Stir Shaken improves call blocking:
- A robocaller initiates a call to a recipient.
- The caller’s phone service provider assigns a level of trust to the call based on the authenticity of the caller ID information.
- The level of trust is then transmitted to the recipient’s phone service provider.
- If the level of trust is low, the recipient’s phone service provider blocks the call.

What is Stir Shaken and how does it help combat robocalls?
Stir Shaken is a technology designed to combat robocalls by verifying the authenticity of caller ID information. It works by using a combination of two protocols: Secure Telephony Identity Revisited (STIR) and Signature-based Handling of Asserted information using toKENs (SHAKEN). These protocols enable phone service providers to verify the identity of callers and ensure that the caller ID information displayed on the recipient’s phone is accurate.
When a call is made, the originating carrier uses STIR to create a digital signature that is attached to the call. This signature is then verified by the receiving carrier using SHAKEN. If the signature is valid, the receiving carrier can be confident that the caller ID information is accurate, and the call is less likely to be a robocall. This helps to prevent scammers from spoofing caller ID information and reduces the number of unwanted robocalls.
How does Stir Shaken verify the authenticity of caller ID information?
Stir Shaken verifies the authenticity of caller ID information by using a combination of digital certificates and cryptographic signatures. When a call is made, the originating carrier creates a digital signature that is attached to the call. This signature is based on the caller’s identity and is verified by the receiving carrier using a digital certificate.
The digital certificate is issued by a trusted authority and contains the carrier’s public key. The receiving carrier uses this public key to verify the digital signature and ensure that it matches the caller ID information. If the signature is valid, the receiving carrier can be confident that the caller ID information is accurate, and the call is less likely to be a robocall.
