Abstract
Systems, methods, circuits, and devices for data protection are provided. In one example, a data processing device incudes a Physical Unclonable Function (PUF) source that is configured to generate PUF values, a bus, a plurality of bus access components that are configured to access the bus, and a masking information generation circuit. The masking information generation circuit is configured to generate masking information for at least one pair of bus access components using at least one PUF value and to transmit said information to the bus access components. The pair is configured in such a way that one bus access component masks the data according to the masking information generated for the pair before the data is sent over the bus and the other bus access component de-masks the data received over the bus according to the masking information generated for the pair.
