Abstract (en)

[origin: WO2015197286A1] The invention relates to checking the authenticity of a balise. For this purpose, an identifier is provided by the balise, which is transmitted as part of the telegram from the balise to the vehicle computer of the rail vehicle. The authenticity of the balise can be verified by the vehicle computer, based on the identifier. The identifier is advantageously transmitted in the ETCS packet 44 according to UNISIG. In addition, a hash value of a cryptographic hash function can be used as an identifier. Furthermore, it is advantageous that any tampering with the telegrams provided by the balise can be detected.
