Abstract (en)
[origin: WO2012130888A1] The invention relates to a method for selectively checking data security sequences of received vehicle-to-x messages. In an operating cycle of a vehicle-to-x communication system, a number of vehicle-to-x messages are received and/or sent, wherein a vehicle-to-x message comprises a data security sequence. Furthermore, a reliability evaluation of the received vehicle-to-x message is performed in the operating cycle by means of a check of the data security sequence, and information content of the received vehicle-to-x message is read out in the operating cycle without a prior check of the data security sequence. The method is characterized in that in the operating cycle a subset of the number of received vehicle-to-x messages is selected according to the information contents and only the data security sequences of selected vehicle-to-x messages are checked. The invention further relates to a vehicle-to-x communication system for selectively checking data security sequences of received vehicle-to-x messages and to the use thereof.
