The automotive field is experiencing a strong technological evolution in recent years. This evolution is leading to the standardization of novel technologies for connected vehicles (both cellular and Wi-Fi-based), enabling them to exchange data with other vehicles and with the infrastructure, to make transportation safer, greener and more autonomous. All these communication technologies define standardized messages for different purposes, that include exchanging data between road users, but also transmitting management information and requesting certificates for secured data transfers. These messages and their content are usually defined as a set of data structures, in turn defined by the Abstract Syntax Notation One (ASN.1) description language.
