Method for a location verification in an intelligent transportation system, ITS, by broadcasting vehicle to everything, V2X, communication, wherein a number of traffic participants are registered in the intelligent transportation system, ITS, wherein a first traffic participant, VT1, uses a service made available by an application, POS-App, of a provider and wherein the service needs a location verification of the first traffic participant, VT1, said method comprising steps in that: - the first traffic participant, VT1, broadcasts a vehicle to everything, V2X, message with a location verification request and a message-ID, ID, - at least one second traffic participant, VTx, receives the message broadcasted by the first traffic participant, VT1, - the second traffic participant, VTx, generates data for an location verification of the first traffic participant, VT1, the data include the message-ID, ID, a location information of the second traffic participant, POS_VTx, and a time information, t_VTx, - the second traffic participant, VTx, signs the data with his VTx-certificate, Cert_VTx, provided in the intelligent transportation system, ITS, - the second traffic participant, VTx, broadcasts an answer, N-VTx, to the location verification request of the first traffic participant, VT1, including the data, the signature, SIG_VTx, of the data and the VTx-certificate, Cert_VTx, of the second traffic participant, VTx, - the first traffic participant, VT1, receives the answer. N-VTx, broadcasted by the second traffic participant, VTx, - the first traffic participant, VT1, sends the answer, N-VTx, of the second traffic participant, VTx, to the application, POS-App, of the provider and - the application, POS-App, of the provider receives the answer, N-VTx, of the second traffic participant, VTx, sent by the first traffic participant, VT1, and the location position of the first traffic participant, VT1, is verificated by evaluating the answer, N-VTx, of the second traffic participant, VTx. - the first traffic participant, VT1, broadcasts a vehicle to everything, V2X, message with a location verification request and a message-ID, ID, - at least one second traffic participant, VTx, receives the message broadcasted by the first traffic participant, VT1, - the second traffic participant, VTx, generates data for an location verification of the first traffic participant, VT1, the data include the message-ID, ID, a location information of the second traffic participant, POS_VTx, and a time information, t_VTx, - the second traffic participant, VTx, signs the data with his VTx-certificate, Cert_VTx, provided in the intelligent transportation system, ITS, - the second traffic participant, VTx, broadcasts an answer, N-VTx, to the location verification request of the first traffic participant, VT1, including the data, the signature, SIG_VTx, of the data and the VTx-certificate, Cert_VTx, of the second traffic participant, VTx, - the first traffic participant, VT1, receives the answer. N-VTx, broadcasted by the second traffic participant, VTx, - the first traffic participant, VT1, sends the answer, N-VTx, of the second traffic participant, VTx, to the application, POS-App, of the provider and - the application, POS-App, of the provider receives the answer, N-VTx, of the second traffic participant, VTx, sent by the first traffic participant, VT1, and the location position of the first traffic participant, VT1, is verificated by evaluating the answer, N-VTx, of the second traffic participant, VTx.
