METHOD FOR PLAGIARISM PROTECTION AND ARRANGEMENT FOR CARRYING OUT SAID METHOD

摘要

The invention relates to a method for plagiarism protection for cryptographic challenge-response methods, wherein an originality test for products that require a secret symmetric or private asymmetric key on the product side is carried out in such a manner that a plagiarism protection service (1) is set up as a web service, which carries out a calculation of the challenge (7) for the product (3) to be tested and a verification (5) of the response (8) for the product (3) and sends the result of the verification in an integrity-protected manner to a testing unit (2) authorised for plagiarism testing, and which, if the cryptographic challenge-response method is not present on the product to be tested after said key has been authenticated and authorised by the product (3) to be tested, can subsequently send software (9, 10) for calculating the response (8) directly to the product online.
