The STIR/SHAKEN framework, an industry-standard caller ID authentication technology, is a set of technical standards and protocols that allow for the authentication and verification of caller ID information for calls carried over Internet Protocol (IP) networks.

While STIR/SHAKEN validates the call's origination from an authorized source, it does not weigh in on the intent of the call itself or whether or not you want to answer the call. This means that a STIR/SHAKEN verified call may still be an unwanted or spam call even though it's a legal call with a known source.

It does this by digitally assigning an attestation rating to a call, indicating whether the originating carrier has authenticated the right of the caller to use the phone number. The receiving carrier uses a decryption key and the attestation rating to validate the caller's number and help identify spoofed calls.

The first bracketed set of information is the header, which is used to understand the PASSporT information, including the type, the algorithm used for cryptography, and x5u, which gives the URI for the certificated needed to validate the signature.

STIR/SHAKEN digitally validates the handoff of phone calls passing through the complex web of networks, allowing the phone company of the consumer receiving the call to verify that a call is in fact from the number displayed on Caller ID.
