Besides all the advantages that C-ITS could bring to the transport system and to our lives, there is an important aspect that must be considered which is security. C-ITS security breaches could be performed by different types of attackers that can have different reasons and different access to the network. One of the C-ITS security solution to ensure confidentiality and authentication in C-ITS communication network is the RFC 8902[al20]. This RFC is specifying the extension of TLS to support C-ITS certificates (IEEE 1609.2[Sys19] and ETSI TS 103 097 v.1.3.1[ETS17]). This extension could be very useful for V2C (Vehicle to cloud) based communication. Such a solution could potentially be a key enabler for additional V2X features that goes beyond day-1 applications which are dedicated to road safety alert and danger alert, typically for Advanced driving-assistance system which requires a certain level of automation. This promising security mechanism can also be used in order to access remote computing resources using both mobile and stationary nodes in a virtualized manner with reduced costs. The goal of this internship is to implement this extension and to test it under near-reality conditions. We aim to provide experimental results about the modified handshake using OpenSSL API or other API supporting TLS 1.3.
