<p>According to the invention, an application process (15) on a portable data carrier (1) can be protected by security processes (13, 14) that are carried out at least twice and that verify a prerequisite for executing the application process (15). To prevent the sequential execution of all security processes (13, 14) and the subsequent execution of the application process (15), at least two of the processes (13, 14,15) are executed in parallel in a processor (2) by a control unit (8) of the data carrier (1). The execution of the application process (15) is only begun if at least one security process (14, 15) has verified the prerequisite for the execution. The invention thus permits the early execution of the application process (15) and a parallel execution to one of the security processes (13, 14). Early results (16) for the application process (15) can thus be created and can optionally be transmitted to a remote terminal (20), to which the data carrier (1) is connected.</p> |
