The scope of this standard is to define secure message formats@ and the processing of those secure messages@ within the DSRC/WAVE system. The standard covers methods for securing WAVE management messages and application messages@ with the exception of vehicle-originating safety messages. It also describes administrative functions necessary to support the core security functions. Purpose 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.
