A vehicular network - or VANET (Vehicular Ad Hoc Network) - is a special type of mobile network in which nodes are vehicles or base stations. These networks are formed by communication systems between automotive vehicles equipped with short range wireless communication devices, or between a vehicle and the fixed infrastructure (base station) located on the roadside. From this technology it is possible to develop various applications, classified into three areas: safety, information and entertainment. This study addresses the security problem with a proposal for implementation and evaluation of the μTESLA, an authentication protocol used to guarantee the authenticity of the origin of messages sent in broadcasting. This protocol generates reduced processing and storage overloads, since only symmetric primitives and delayed disclosure of keys are used to carry out the authentication of messages, not requiring more complex mechanisms such as digital signature and asymmetric encryption. This implementation has been tested and validated through the use of two free and open source simulators, namely: VanetMobiSim, which was used to provide the traffic mobility patterns, and NS-2, which was use to simulate the vehicular network and their packet transfers (messages)
