Additional System Processing - DUIS

When the DCC receives a Response indicating Success from an Update Security Credentials (Device) the DCC Systems are updated to record which Device Certificates are currently in use by the Device.

When the DCC receives no Response from an Update Security Credentials (Device) the DCC Systems shall initiate a Command using both the old and new Key Agreement Device Certificates to determine which Key Agreement Device Certificates is currently in use by the Device. If the DCC receives a Response to the Command using the new Key Agreement Device Certificate then the DCC Systems are updated to record which Key Agreement Device Certificate is currently in use by the Device.
