As the EVSEs must have the V2G Root or the MO roots installed in order to verify the authenticity of the Contract certificates.
The CPMS must be able to retrieve these roots from the Root Certificate Pool, which is used for communication with various Certificate Authorities of ISO 15118 participants (V2G, OEM, MO).
The stored root certificates are checked regularly with automated processes, and expired or revoked certificates are deleted.
The storage of root certificates is executed manually by Hubject administrators. Other systems of the Hubject PnC Ecosystem use this pool as the mutual trust store.
