According to the WInnForum requirements, certain CBSDs require that a Certified Professional
Installer (CPI) validates the installation parameters before they are sent to the SAS.
Figure 1. CPI identity validation flow
In the SAS Portal API, we need to validate that a given user has a valid CPI certification before
they can call the
SignDevice()
method. We achieve this with the following two-step validation method:
A user with the role_cpi role calls the
GenerateSecret()
method, which returns a secret.
The user signs the secret with their private key and uses the
ValidateInstaller()
method to send the encoded version back as a
JWT, along with their CPI ID and
the original secret. For more details about token creation, see
JSON Web Token format.
The CPI role privileges become effective only after a user with the role_cpi role
successfully completes the CPI validation flow.
