Hardware security module and debugging method of such a module

摘要

The present invention relates to the field of debugging of compiled programs in a hardware security module such as a microprocessor card. A module according to the invention includes a microprocessor and a compiled program to be executed by the microprocessor in order to carry out an operation. The compiled program includes at least one debugging instruction which whether or not it is executed does not modify the execution of the operation. And, the hardware security module includes an element of inhibiting or activating the debugging instruction during the execution of the compiled program.
