2	Implementation Models What is necessary to get started? How to handle possible transitions? Where is the value to the private sector? What kind of partnership models might be possible?
3	Keep in Mind… DOT’s first priority is to enable crash avoidance safety applications Under a mandated system… Not opt in No user choice or ability to disable No optional subscription fees (for core safety features) Need adequate protections for privacy, non-traceability for trips Controlled environment necessary for systems that interface with vehicle electronics Message validity important for safety applications – requires “security system” – network and back end processes Security network may be based on DSRC, cellular networks, or hybrids of DSRC, cellular and WiFi

6	Getting Started Considerations to Support Initial Deployment (from the Light Vehicle Manufacturers)… A central certificate management entity (CME) is required to support security credentials management Structure of the CME… Should be planned to allow graceful evolution from initial deployment to full deployment system At initial deployment, size and complexity of SCMS expected to be reasonable due to relatively small number of equipped vehicles On-board security functions (SW, HW, Processing, Memory, etc.) Should be planned for long lifetime of vehicles right from initial deployment Interaction between the on-board security and the CME Should be supported with limited DSRC security communication at strategic locations for initial deployment (Opt-in) Alternate communications to supplement increased level of interaction between the on-board security and the CME
