Abstract
Eine Nachricht (N) umfasst eine erste Einmalkennung (EK1) oder einen abhängig von der ersten Einmalkennung (EK1) ermittelten ersten Nachrichtenprüfwert (NP1). Die Nachricht (N) wird per Funk empfangen. Eine per Funk ausgestrahlte zweite Einmalkennung (EK2) wird unabhängig von der Nachricht (N) empfangen. Die Nachricht (N) wird abhängig von der ersten Einmalkennung (EK1) und der zweiten Einmalkennung (EK2) auf ihre Gültigkeit überprüft. Die Nachricht (N) wird als gültig erkannt, wenn die erste Einmalkennung (EK1) und die zweite Einmalkennung (EK2) übereinstimmen oder wenn der erste Nachrichtenprüfwert (NP1) mit einem zweiten Nachrichtenprüfwert (NP2) übereinstimmt, der abhängig von der zweiten Einmalkennung (EK2) ermittelt wird, oder wenn eine abhängig von der zweiten Einmalkennung (EK2) ermittelte dritte Einmalkennung (EK3) mit der ersten Einmalkennung (EK1) übereinstimmt. Andernfalls wird die Nachricht (N) als ungültig erkannt. A message (N) comprises a first one-time code (EK1) or a first message check value (NP1) determined as a function of the first one-time code (EK1). The message (N) is received by radio. A radio-broadcast second one-time signal (EK2) is received independently of the message (N). The message (N) is checked for validity depending on the first one-time code (EK1) and the second one-time code (EK2). The message (N) is recognized as valid if the first one-time code (EK1) and the second one-time code (EK2) match or if the first message check value (NP1) matches a second message check value (NP2) which depends on the second one-time code (EK2 ), or if a third one-time identifier (EK3) determined as a function of the second one-time identifier (EK2) agrees with the first one-time identifier (EK1). Otherwise, the message (N) is recognized as invalid.
