Secure Telephone Identity
The Secure Telephone Identity Governance Authority is a critical body helping the industry achieve success in mitigating the problem of unwanted robocalling. Working with the IETF's STIR (Secure Telephone Identity Revisited) protocol, the ATIS-SIP Forum Signature-based Handling of Asserted information using toKENs (SHAKEN) specification specifies a practical mechanism for authenticating calls. Attaching a "digital signature" will help consumers to once again trust their caller ID.
ATIS is managing the Secure Telephone Identity Governance Authority (STI-GA), defining the rules governing the certificate management infrastructure to ensure effective use and security of SHAKEN certificates.
