Abstract: In a method for issuing an access authorization for a software product provided on an application server, provision is made for a license server to establish, electronically sign and transfer a license token to the application client, which transmits the license token to the application server. Since the application client supplies its access authorization for access to the software product with the request for the software product, a rapid and efficient checking of the access authorization is possible, even without a connection between the license server and the application server during the request.
