Abstract

For a secure communication between a remote unit and a central unit, keys of a corresponding key set are necessary in the remote unit and the central unit. According to the present invention, information with respect to how the remote unit generates a key for the corresponding key set is stored in the central unit. The keys of the corresponding key set are independently generated in the remote unit and the central unit. Advantageously, this allows for a secure communication while reducing the required memory in the remote unit.
