Abstract

A device for processing a program code with a plurality of subprogram calls, a subprogram corresponding to a subprogram call taking place by means of an allocation table, has a security module having the allocation table and a processor for using the program code. Access to the allocation table in the security module is restricted. The processor for using the program code is formed to retrieve, responsive to a request for subprogram data, using authorization information, subprogram data via the allocation table in the security module.
