Cooperative ITS security framework: Standards and implementations progress in Europe

A number of standardization organizations and European projects dealt with security and privacy issues in Cooperative Intelligent Transport Systems (C-ITS). In this paper, we present recent standardization activities and implementations of security services in various cooperative driving applications (Release 1 use cases and next stages). We discuss the validation of C-ITS embedded systems security standards and the Public Key Infrastructure (PKI) implementation plans. We present already standardized messages as well as a new proposal for standardization. Already standardized messages focus on vehicular safety and traffic efficiency, while our proposal targets service advertisement.
