VANETs are subset of Mobile Ad hoc NETworks (MANETs) in which vehicles act as nodes. Vehicles are equipped with wireless On-Board Units (OBUs), to perform communication. In VANET, message authentication, a fundamental issue, is traditionally defined as the task of authenticating a message in terms of integrity and identification check. To deal with message authentication issue, a cooperative approach, known as cooperative message authentication scheme is introduced. The scheme, however, has been explored to alleviate authentication overhead on individual vehicle and thereby eliminating redundant authentication efforts on the same message by different vehicles.
