<p>A method is proposed for distributed creation of a program for a programmable portable data carrier (10) e.g. a smart card. Program source text (Q) is created on a user computer (20), compiled and linked into executable program code (C) on a spatially separate compiler server (30), and the executable program code (C) loaded into data carrier (10) again via the user computer (20). A secure end-to-end link is set up for the data exchange between data carrier (10) and compiler server (30). For this purpose, the data carrier (10) is provided, in a precompletion step, with software tools for final processing that permit a transport code (U, CSSL, UCSM) provided in a transient format to be converted into executable program code (C). the transport code (U, CSSL, UCSM) is secured by encryption mechanisms. The transfer of the executable program code (C) generated by the compiler server (30) to the data carrier (10) is effected in the transient format (U, CSSL, UCSM).</p> |
