Abstract (en)
[origin: EP1936527A1] The method involves inserting dummy operations e.g. counter measures (111-114), in which a part of the dummy operations is not fully executed, where the counter measures are random-delays. The number of dummy operations which are not fully executed is variable between two executions of a source code and is recalculated at each execution of the source code, where the dummy operations include bodies (16, 24) and introductory parts (12, 15, 17, 23).
