METHOD FOR EXECUTING PROCESSING IN A SECURE DEVICE

摘要

The invention is a method for executing processing in a secure device containing a microprocessor. The processing includes a task of a first type. The first type corresponds to the operations executable by the microprocessor or by a component specifically designed for the first type. The secure device also includes a computational hardware unit specifically designed for executing operations of a second type. Said second type is different from the first one. The method includes the steps of: -selection of a resource associated with the task, with the resource including the computational hardware unit, -assignment of the selected resource to the task, and -execution of the task using the computational hardware unit by executing at least one of the operations of the second type, thus diverting the computational hardware unit (U1) with respect to the use which it was originally designed for.
