Abstract

A method for access or starting verification for a vehicle using a mobile identification encoder and at least two antennas located in or on the vehicle at different locations includes: the antennas emitting electromagnetic signals at alterable times, wherein the electromagnetic signals are emitted in transmission blocks having alterable specific properties and wherein a plurality of transmission blocks are strung together to form a communication message in which each transmission block adopts an alterable position in time, the identification encoder receiving the electromagnetic signals emitted by the antennas and processing them to generate a response signal, and altering at least one of the times at which the individual antennas are actuated, the specific properties of the individual transmission blocks, and the position of the individual transmission blocks in time in the communication message in accordance with a cryptographical method.
