A team of OEMs, US DOT personnel, automotive suppliers and security experts have examined the technical feasibility and risks associated with a security system for V2V warning-only applications, under a certain set of assumptions.  The proposed security model developed needs to be built and tested to validate the conclusions from this study.
1.
1.Technical solutions for the initial and full security deployment models have been identified that DOT and the OEMs believe are feasible..
2.
2.The on-board system will require additional special hardware for security, which is technically feasible and is not expected to considerably increase the cost.
3.
3.The team believes that connectivity will not be required for the first three years.  After that, more frequent connectivity is likely to be required, but is increasingly difficult to estimate.  Connectivity options will be examined in a follow-on study.
4.
4.SCMS (Security Certificate Management System) technical risks are well-understood from implementations of similar systems, although the V2V PKI is considerably larger than any previous system.  SCMS costs, funding and organization are being examined in a follow-on study.
5.
5.OEMs believe that privacy and tracking risks will likely require a combination of technical and policy solutions.
