%X <p>The development of vehicular Ad hoc networks (VANETs) require a secure in-vehicle network. Controller area network (CAN) is a popular protocol applied in in-vehicle network. In order to enhance CAN bus security, abroadcast authentication algorithm, which establishesthe samemessage authentication code(MAC) list among all the electronic control unit (ECUs) with stream ciphers, was proposed. The senderjust needs to attach a MAC sequence to the data frame and the receiver compares the received MAC sequence with the corresponding one in the established list. This algorithm can be adapt to the characteristic ofthe CAN bus communication. The structure of the authentication system was described in detail. Finally,the security and delay performance was analyzed. The probability of miss and the bus overhead was provided.</p>
