Keys/Certificates used for Registration and Flight Logs



As per my understanding, we have RFM Key Pair and Manufacturer’s certificate in the NPNT ecosystem.

My question below.

  1. In Drone Device Register API request, there is mention of signing the drone data. This signing using the Manufacturer’s DSC (or public key) OR RFM’s public key?
    This is as per section 3.2.3 in RPAS Guidance manual

  2. As per the RPAS Manual, individual flight logs are signed using RFM private key. These individual logs then bundled per PA and again signed using RFM public key?
