1. A method for exchanging of information in an intelligent transport system between a plurality of intelligent transport system stations (ITS-Ss) in said intelligent transport system (ITS) using a wireless communication channel, said exchanging of information comprising composing, transmitting, receiving and/or decoding at least part of ITS messages at and/or between said plurality of ITS-Ss,
wherein each of said plurality of intelligent transport system stations (ITS-Ss) comprises at least one sensor arranged to perceive, for example in the form of objects and/or free-space, in at least one geographical area within said traffic environment, is arranged to act both as a sender ITS-S and a receiver ITS-S, and is arranged to use, as said ITS messages, collective perception messages (CPMs) containing at least information about the perception within a traffic environment, and
wherein an ITS communications security architecture including at least one security layer as a horizontal security management entity in the ITS communication stack is configured to provide security services to ITS station communications,
said method comprising the steps of:
obtaining an information and misbehavior verification related requirement from the at least one security layer;
composing an area perception request (APR) based on said information and misbehavior verification related requirement;
sending, from an ITS-S acting as a sender ITS-S, the APR composed based on said information and misbehavior verification related requirement, and requesting perception information from another ITS-S capable of perceiving with respect to said information and misbehavior verification related requirement;
receiving, from said another ITS-S, the requested perception information in a subsequent CPM of said another ITS-S; and
verifying information sent by other ITS-Ss or verifying misbehavior based on the perception information received from said another ITS_S.
