Abstract
A method for downloading information into a secure non-volatile memory of a secure embedded device (SED) during a manufacturing or personalization process. The method involves communicating the information and a software program from a device to a temporary storage memory of the SED. The method also involves starting the software program provided to facilitate an initialization of a first key and to facilitate a transfer of at least a portion of the information from the temporary storage memory to the secure non-volatile memory. In response to starting, the software program, the first key is initialized and the portion of information is transformed into transformed information locally at the SED using at least one of a scramble algorithm and a cipher algorithm. Thereafter, the transformed information is written to a memory element of the secure non-volatile memory.
