Abstract
A hardware secure element includes a processing unit and a receiver circuit configured to receive data comprising a command field and a parameter field adapted to contain a plurality of parameters. The hardware secure element also includes at least one hardware parameter check module configured to receive at an input a parameter to be processed selected from the plurality of parameters, and to process the parameter to be processed to verify whether the parameter has given characteristics. The hardware parameter check module has associated one or more look-up tables configured to receive at an input the command field and a parameter index identifying the parameter to be processed by the hardware parameter check module, and to determine for the command field and the parameter index a configuration data element.
