Secure bootloader for securing digital devices

A method of communicating from a transmitter to a receiver over a communication medium. For the transmitter, the method includes the step of formatting data into a data stream to be communicated across the communications medium. This data stream comprises a plurality of headers (PACK HEADER). Moreover, for each of the plurality of headers, the method performs two steps. First, the method modifies information encoded by the header by performing a bitwise logical operation between selected bits of the header (B) with a predetermined bit pattern (A). Second, the method transmits the plurality of headers on to the communications medium. For the receiver, the method includes the step of receiving the plurality of headers from the communications medium. Additionally, for each of the received headers, the receiver recovers the information encoded by the header.
