METHOD FOR AUTHENTICATED COMMUNICATION BETWEEN A FIRST COMMUNICATION PARTNER AND A SECOND COMMUNICATION PARTNER, WHERE THE FIRST COMMUNICATION PARTNER AND / OR THE SECOND COMMUNICATION PARTNER IS A TRAFFIC PARTICIPANT AND / OR PART OF A TRAFFIC INFRASTRUCTURE, SYSTEM, COMMUNICATION PARTNER, COMPUTER PROGRAM, AND COMPUTER READABLE MEDIUM

摘要

It becomes a method for authenticated communication between a first communication partner and a second communication partner, where the first communication partner and/or the second communication partner is a road user and/or part of a traffic infrastructure, wherein, in addition to an optically detectable first identity information, the first communication partner has a further first identity information or is associated with it, and wherein the second communication partner has, in addition to an optically detectable second identity information, a further second identity information or this is associated,where the procedure involves the following steps:--in a first step, at a first time by the first communication partner a first distance information to the second communication partner and the optically detectable second identity information of the second communication partner is determined or detected and a first message is transmitted wirelessly, wherein the first message the first distance information, comprises the optically detectable second identity information of the second communication partner, the optically detectable first identity information and the further first identity information of the first communication partner, and a signature information of the first communication partner,--in a second step, the first message is received by the second communication partner and as part of the first message the optically detectable second identity information of the second communication partner detected or detected and the signature information verified by the second communication partner,--in a third step, at a second time by the second communication partner a second distance information to the first communication partner and the optically detectable first identity information of the first communication partner is determined or detected and a second message is transmitted wirelessly, wherein the second message the second distance information, the optically detectable first identity information and/or the further first identity information of the first communication partner,the optically detectable second identity information and the further second identity information of the second communication partner and a further signature information of the second communication partner comprises, wherein the second message is received by the first communication partner and the further signature information is verified by the first communication partner.
