Abstract
In a method and arrangement for securely exchanging data between a first data processing unit and a second data processing unit, a secure communication channel is established between the first data processing unit and the second data processing unit in a communication configuration step, and a first message is transmitted from the second data processing unit to the first data processing unit via the secure communication channel in a data transmission step. During the data transmission step, the second data processing unit generates a second message by appending a predetermined annex to the first message and a third message by encrypting the second message using a secret key that is available only in the first data processing unit and in the second data processing unit and then transmits the third message to the first data processing unit.
