<p>The invention concerns a method for protecting, from a unit, a vulnerable software against its unauthorised use, said software operating on a data processing system. The method consists in creating a protected software: by selecting in the vulnerable software source, at least a conditional jump; by modifying the vulnerable software source so that a second part of the execution executed in a unit executes at least the functionality of at least a selected conditional jump and provides the data processing system with an information enabling to track the execution at the selected site.</p> |
