At one point of the communication line, a first authentication code generation module is provided, which is dedicated to the first vehicle. At another point of the communication line, a second code processing module is provided, which is dedicated to the second vehicle. The first authentication code generation module is configured to send identification information, authentication information, and/or encryption keys. The second code processing module is configured to process and send back identification information, authentication information, and/or encryption keys, especially processed and/or modified identification information, authentication information, encryption keys. ## Claims ### Claim 1 A system for establishing an intervehicle communication for a first and a second commercial vehicle, comprising: at least one physical communication line, wherein the at least one physical communication line is bidirectional; a first authentication code generation module provided at one point of the at least one physical communication line, which the first authentication code generation module is dedicated to the first commercial vehicle; a second code processing module provided at another point of the at least one physical communication line, which second code processing module is dedicated to the second commercial vehicle, wherein the first authentication code generation module is configured to send identification information and/or authentication information and encryption keys, and wherein the second code processing module is configured to process and send back processed and/or modified information and/or authentication information, and encryption keys, wherein the at least one physical communication line is a pneumatic line, wherein the first authentication code generation module and the second code processing module are configured and arranged such that the identification information and/or authentication information and encryption keys are transmitted by at least one pressure signal and/or a series of pressure signals, corresponding to and/or representing the identification information and/or authentication information and encryption keys. ### Claim 2 (depends on 1) The system according to claim 1, wherein: the first commercial vehicle is a truck, and the second commercial vehicle is a trailer. ### Claim 3 (depends on 1) The system according to claim 1, wherein: the first commercial vehicle is a trailer, and the second commercial vehicle is another trailer. ### Claim 4 A method for establishing an intervehicle communication for a first and a second commercial vehicle, comprising: providing at least one physical communication line, wherein the at least one physical communication line is bidirectional and wherein the at least one physical communication line is a pneumatic line, wherein, at one point of the at least one physical communication line, a first authentication code generation module is provided, which is dedicated to the first commercial vehicle, wherein, at another point of the at least one physical communication line, a second code processing module is provided, which is dedicated to the second commercial vehicle; generating a first authentication code generation at the first commercial vehicle; sending, by the first authentication code generation module, identification information and/or authentication information and encryption keys to the second commercial vehicle; processing and sending back, by the second code processing module, identification information and/or authentication information and encryption keys to the first commercial vehicle; and transmitting the identification information and/or authentication information and encryption keys by at least one pressure signal and/or a series of pressure signals, which correspond(s) to and/or represent(s) the identification information and/or authentication information and encryption keys. ### Claim 5 (depends on 4) The method according to claim 4, wherein the method is performed by using a system comprising: the at least one physical communication line; a first authentication code generation module provided at one point of the at least one physical communication line, which first authentication code generation module is dedicated to the first commercial vehicle; a second code processing module provided at another point of the at least one physical communication line, which second code processing module is dedicated to the second commercial vehicle, wherein the first authentication code generation module is configured to send the identification information and/or authentication information and encryption keys, and wherein the second code processing module is configured to process and send back the identification information and/or authentication information and encryption keys, wherein the at least one physical communication line is a pneumatic line, wherein the first authentication code generation module and the second code processing module are configured and arranged such that the identification information and/or authentication information and encryption keys are transmitted by at least one pressure signal and/or a series of pressure signals, corresponding to and/or representing the identification information and/or authentication information and encryption keys. ### Claim 6 (depends on 1) An authentication code generation module for a system for establishing an intervehicle communication according to claim 1, wherein: the authentication code generation module is configured to send identification information and/or authentication information and and/or encryption keys. ### Claim 7 (depends on 1) A code processing module for a system for establishing an intervehicle communication according to claim 1, wherein: the code processing module is configured to process and send back processed and/or modified identification information and/or authentication information and and/or encryption keys.
