Abstract
A method for radio communication between mutually mobile objects. Prior to radio communication between the objects, calculations are preformed with a communication and calculation unit of a first of the objects to produce established data, answer codes are generated from the established data, and one of the answer codes is selected for communication to a second of the objects. The communication between the objects is carried out, including transmission of the selected answer code from the first object to the second object and transmission of data from the second object to the first object. After radio communication between the objects, calculations are performed with the communication and calculation unit of the first of the objects. A final result of the communication of between the objects and calculations performed by the communication and calculation unit of the first of the objects is stored after radio communication between the objects. Outside communication with the communication and calculation unit is prevented after communication between the objects, during the performance of calculations by the communication and calculation unit of the first of the objects and storage of…
