Title : Bootstrapping STIR Deployments with Self-Signed Certs and Callbacks
Authors : Jonathan Rosenberg

Filename : draft-rosenberg-stir-callback-00.txt
Pages : 16

Abstract:
Robocalling has become an increasing problem in the Public Switched
Telephone Network (PSTN). A partial remedy for it is the provision
of an authenticated caller ID in the PSTN, which today is lacking.
Secure Telephone Identity Revisited (STIR) provides this through the
usage of signed payloads in Session Initiation Protocol (SIP) calls.
However, STIR deployment requires a global certificate system which
allows for worldwide issuance of certifications that attest to which
numbers a provider is responsible for. Such a system is likely to
take years to rollout. To accelerate STIR deployment, this draft
proposes a technique wherein STIR can be used without certificates
that attest to number ownership. This is done through a combination
of self-signed certificates, reverse callbacks and cached
validations.
