摘要：In a method and arrangement for securely exchanging data between a first dataprocessing unit and a second data processing unit, a secure communication channel isestablished between the first data processing unit and the second data processing unit ina communication configuration step, and a first message is transmitted from the second
data processing unit to the first data processing unit via the secure communicationchannel in a data transmission step. During the data transmission step, the second dataprocessing unit generates a second message by appending a predetermined annex to thefirst message and a third message by encrypting the second message using a secret keythat is available only in the first data processing unit and in the second data processingunit and then transmits the third message to the first data processing unit.
