Background
Vehicle safety is a key application category for the DSRC spectrum.
We are reaching the limit of passive safety systems
WAVE enables and enhances proactive and preventive safety systems
Cooperative vehicle status and sensor information sharing is essential for such vehicle safety applications.
True for both vehicle-infrastructure and vehicle-vehicle scenarios
Such information (e.g. vehicle velocity) will necessarily be open for all to hear
ASTM was formerly “American Society For Testing and Materials”, now renamed to simply “ASTM International”

3. Anonymity Requirement

Anonymity Requirement
Permanent and unique MAC addresses of WAVE radios makes it easy to use such information against the owners.
In general, the communication stack should not in itself reveal the identity of the car and by extension, the driver.

Anonymous MAC Address
MAC address of the WAVE radio therefore is required to support randomized MAC address
Other security and privacy related issues are studied in ongoing and upcoming security projects
