Zusammenfassung:A method for remote verification of the integrity of a computer program in a computing unit to be checked using a verification unit. The computer program is specified by a reference program code and is in the form of stored program code in the computing unit to be checked. The method includes: selecting, by the verification unit, a pair from a list of pairs in which each pair includes a random character string and a reference check value calculated using a check value function based on the random character string of the pair and the reference program code; transmitting the random character string of the pair to a validation unit; receiving a comparison check value calculated using the check value function based on the transmitted random character string and the stored program code; comparing the received comparison check value to the reference check value of the selected pair.
