Abstract

A hardware secure element is described. The hardware secure element includes a microprocessor and a memory, such as a non-volatile memory. The memory stores a plurality of software routines executable by the microprocessor. Each software routine starts at a respective memory start address. The hardware secure element also includes a receiver circuit and a hardware message handler module. The receiver circuit is configured to receive command data that includes a command. The hardware message handler module is configured to determine a software routine to be executed by the microprocessor as a function of the command, and also configured to provide address data to the microprocessor that indicates the software routine to be executed.
