Chip card for monitoring data integrity and software development integrity, has software module generating software counter-measures and counter-measures relative to redundant data engaged or integrated into components of tool chain

摘要

The card (4) has a software module for generating software counter-measures (1) engaged or integrated into components of a tool chain, where the components of the tool chain are a preprocessor, a compiler, an assembler and a linker. The software counter-measures are providing data, address value and return addresses with checksums or redundant data. Hardware countermeasures are activated and deactivated in accordance with requirements of documentation (3). The software module generates counter-measures relative to the redundant data and test routines. An independent claim is also included for a method for operating a chip card.
