How It Works
STIR (Secure Telephony Information Revisited) is a a technical standard that allows telecommunications service providers (TSPs) to certify the identity of callers. SHAKEN (Signature-based Handling of Asserted information using toKENs) is the framework for the implementation of STIR into providers’ networks. Simply put, STIR defines how you could implement the protocol, while SHAKEN documents how you will implement the protocol.
