Abstract
Secure serial bus communication methods and devices suitable for automotive applications. An illustrative sensor IC includes: a sensor controller that operates a transducer to obtain measurement data formattable as data packets; a scrambler that masks each data packet with a scrambling operation before that data block is sent via a serial bus to a bus controller device, said scrambling operation having a secret configuration and/or secret initial state; and an integrated circuit component that operates on a seed value to derive the secret configuration and/or secret initial state.
