In today’s digital age, telecommunication plays a vital role in almost every aspect of our lives. However, along with the numerous advantages, there are also potential risks and challenges that need to be addressed. One such challenge is the issue of caller ID spoofing, where malicious actors manipulate the information that is displayed on a recipient’s caller ID screen. This deceptive practice often leads to fraudulent activities and an increased level of distrust among consumers. To combat this problem, the telecommunications industry has developed a revolutionary solution. In this article, we will delve into the basics of Stir/Shaken, explore its technical aspects, discuss its impact on businesses, and take a glimpse into its future.

The basics of Stir/Shaken

Before we dive into the technical details, let’s start by defining what Stir/Shaken actually means. Stir comes from Secure Telephony Identity Revisited and Shaken from Signature-based Handling of Asserted information using toKENs. They are two frameworks that work in tandem to authenticate and verify the origin of a caller’s phone number. The process involves the use of digital certificates and cryptographic signatures, ensuring that the information displayed on the recipient’s caller ID is trustworthy and accurate.

Defining Stir/Shaken

In simple terms, Stir/Shaken is a set of standards and protocols that enable telephone service providers to verify the caller’s identity and securely transmit that information to the recipient. It aims to restore the public’s trust in Caller ID information by reducing the risks associated with caller ID spoofing. By leveraging digital certificates and cryptographic signatures, Stir/Shaken ensures that the caller’s phone number cannot be tampered with or falsified.

The importance of Stir/Shaken in telecommunications

With the rise of advanced technology, caller ID spoofing has become a widespread issue, allowing scammers and fraudsters to deceive unsuspecting individuals. By implementing Stir/Shaken, telecommunication companies can effectively combat this problem and create a more secure environment for their customers. Furthermore, it bolsters consumer trust and confidence in phone calls, as recipients can be more confident that the displayed caller ID is accurate and reliable.

Let’s take a closer look at how Stir/Shaken works in practice. When a call is made, the originating telephone service provider (OSP) applies the Stir/Shaken framework to the call. The OSP generates a digital certificate that contains information about the caller’s identity and signs it using a cryptographic signature. This certificate serves as proof of the caller’s authenticity.

Once the call reaches the recipient’s telephone service provider (RSP), the RSP verifies the digital certificate and cryptographic signature. This verification process ensures that the caller’s phone number has not been tampered with or spoofed. If the verification is successful, the recipient’s caller ID displays the caller’s phone number along with a verification mark. This indicates that the call has been authenticated by Stir/Shaken.

It’s important to note that Stir/Shaken does not prevent unwanted or spam calls from reaching recipients. Instead, it focuses on verifying the authenticity of the caller’s identity. However, by implementing Stir/Shaken, telecommunication companies can provide their customers with the necessary tools and information to make informed decisions about answering or blocking calls.

The technical aspects

Now that we have a general understanding of Stir/Shaken, let’s explore the technical intricacies behind its implementation.

The role of authentication and verification

At the core of Stir/Shaken is the process of authentication and verification. Service providers authenticate the caller’s identity by validating the digital certificate associated with their phone number. This certificate is issued by a trusted authority and serves as proof of the caller’s legitimacy. It contains information such as the caller’s name, phone number, and other relevant details.

Once the authentication is complete, the phone call is assigned a cryptographic signature. This signature is a unique code generated using complex algorithms, ensuring the integrity and authenticity of the call. It acts as a digital seal, providing a secure and tamper-proof connection between the caller and the recipient.

To further enhance security, cryptographic signatures are verified by the recipient’s service provider. The verification process ensures that the call has not been tampered with during transmission. If the signature matches with the associated digital certificate, the recipient can trust the displayed caller ID and have confidence in the authenticity of the call.

How Stir/Shaken combats caller ID spoofing

Caller ID spoofing often involves fraudsters impersonating a legitimate phone number to deceive recipients. Stir/Shaken addresses this issue by enabling service providers to mark each call with an attestation level. An attestation level indicates the level of trust and verification the service provider has assigned to the call.

There are three primary attestation levels: Full Attestation, Partial Attestation, and Gateway Attestation. Full Attestation indicates that the caller’s identity has been fully verified by their service provider, providing the highest level of trust. Partial Attestation signifies that the call has been authenticated but may have originated from an intermediate entity, such as a call forwarding service. Gateway Attestation is assigned to calls originating from the Public Switched Telephone Network (PSTN) gateway, indicating a lower level of trust.

By displaying the attestation level alongside the caller ID, recipients can make informed decisions about whether to answer the call or exercise caution. This transparency acts as a deterrence against fraudulent activities and enhances the overall security of the telecommunication ecosystem.

Moreover, Stir/Shaken also encourages collaboration between service providers to combat caller ID spoofing effectively. By sharing attestation information and implementing consistent verification processes, the industry as a whole can create a robust defense against fraudulent calls. This comprehensive framework strengthens the security of phone calls and fosters trust in the telecommunication ecosystem.

Its impact on businesses

Stir/Shaken not only benefits individual consumers but also has significant implications for businesses operating in the telecommunications sector. As technology continues to advance, the need for secure and trustworthy communication channels becomes increasingly crucial for businesses to maintain a competitive edge in the market.

Implementing Stir/Shaken protocols requires a certain level of technical expertise and infrastructure investment. Companies need to ensure that their systems are capable of supporting these protocols effectively to avoid disruptions in their communication services.

Stir/Shaken and regulatory compliance

Regulatory bodies, have recognized the importance of tackling caller ID spoofing. The Federal Communications Commission (FCC) for example has mandated the implementation of Stir/Shaken in US. This means that US telecommunication companies must adopt Stir/Shaken protocols to meet regulatory compliance requirements. Businesses that comply with these regulations demonstrate their commitment to protecting their customers’ privacy and security.

Moreover, regulatory compliance goes beyond just meeting the basic requirements. It also presents an opportunity for businesses to showcase their dedication to upholding industry standards and best practices. Companies that go above and beyond not only fulfill regulatory obligations but also position themselves as leaders in promoting transparency and security in the telecommunications landscape.
