The safety-critical nature of many DSRC/WAVE applications makes it vital that services be specified that can be used to protect messages from attacks such as eavesdropping, spoofing, alteration, and replay. Additionally, the fact that the wireless technology will be deployed in personal vehicles, whose owners have a right to privacy, means that in as much as possible the security services must be designed to respect that right and not leak personal, identifying, or linkable information to unauthorized parties. This standard describes security services for WAVE management messages and application messages, with the exception of vehicle-originating safety messages, to meet these requirements. It is anticipated that vehicle-originating safety messages will be added in an amendment to this standard.
