VANET is recognized as an important component of Intelligent Transportation Systems (ITS). To successfully deploy VANET, security is one of the major challenges that must be addressed. A very important one is to guarantee the security of vehicle-generated reports. In what regards security, selfish vehicles may attempt to clear up the way ahead or mess up the way behind with false traffic reports; criminals being chased may disseminate bogus notifications to other vehicles in order to block police cars. Such attacks may result in serious harm, even loss of lives.
