Abstract
An example secure embedded device includes a secure non-volatile memory coupled to a processor. The processor provides a scramble or cipher key and uses a scramble algorithm or a cipher algorithm to scramble or cipher information received from an external device into transformed information. The processor writes a least a portion of the transformed information to a plurality of memory locations of the secure non-volatile memory. The plurality of memory locations is based on the scramble or cipher key.
