Based on the PRESERVE PKI, the Pilot PKI of C2C-CC is a success story. It received a lot of attention (about 1000 ITS stations have been registered, about 900 long-term certificates and more than 3000 pseudonym certificates were issued so far), and was used during the ETSI Plugtest in November 2013.
Fraunhofer SIT and Escrypt are highly involved into the development and maintenance of the C2C-CC Pilot PKI, and thus, wrote an article for the 12th C2C-CC newsletter (February 2014) where they describe the work done and the future challenges.
