    • PROBLEM TO BE SOLVED: To authenticate wireless communications between a vehicle base station and a transponder.SOLUTION: Two or more antennas including at least one within a vehicle are respectively driven using driving currents multiplied by different superposition factors for at least two iteration cycles. Separate vector components of the respective fields emitted by the antennas are used to calculate the superposition factors. For each cycle, each antenna is concurrently driven using the same phase using the driving currents respectively multiplied by the superposition factors, and superposed vector components for a superposed signal including signals from both antennas are detected. Communications are authenticated on the basis of whether the superposed vector components detected for the superposed signal of each cycle are within a system error-based range of the sum of the vector components for each of the internal and external antennas, multiplied respectively by the superposition factors for the antenna from which the vector components are received.

    • PROBLEM TO BE SOLVED: To provide an access control method, device and architecture which perform an access right to components with reliability in an electronic system.
      SOLUTION: In the system 100, the access control device prohibits data transfer on a bus between a pair of an initiator 110 and a target 120 which are not permitted. A permission matrix for identifying access permission of each initiator to each target is maintained. An access device monitors the bus to determine identification information of the initiator and an intended target. If the initiator has an appropriate access right to the target, generation of bus communication is permitted, and if not so, the communication is intercepted, and an error signal goes into effect. In order to provide further security, an identifier of the initiator which is local to the access control device is communicated to the access control device via direct wiring connection to each initiator.
