STI-GA Call for Certificate Authorities

Certificate Authorities will play a critical role in mitigating illegal robocalls.

WASHINGTON, DC — Implementation of STIR/SHAKEN is a critical mission in the fight against illegal robocalls and caller ID spoofing. The Secure Telephone Identity Governance Authority (STI-GA) manages the rollout of this solution and is seeking interest from organizations that would like to serve as STI Certificate Authorities (CAs).

The ATIS SHAKEN specifications (ATIS100084-E) note “the STI-CA serves as the Root CA for the STI certificates used to digitally sign and verify telephone calls. The STI-CA provides the service of issuing valid STI certificates to the validated service providers (SPs). There will likely be a number of STI-CAs, supporting specific or multiple SPs, depending upon the SP.” STI-CAs will assign, renew and revoke these STI certificates. One or more CAs may also be involved in the testing of the STI-Policy Administrator system including its interfaces.

December 11, 2019 is the targeted date to have the STIR/SHAKEN ecosystem fully operational, and the STI-GA is now creating a list of interested Certificate Authorities. Interested organizations should contact Brent Struthers, ATIS Director – STI Governance Authority.
