Abstract: In one example, an integrated circuit (IC) is provided that includes data circuitry and a processing circuitry. The data circuitry is configured to provide data to be transferred to a different circuitry within the IC or to an external IC. The processing circuitry is configured to: read the data provided by the data circuitry before it is transferred to the different circuitry or the external IC; calculate a first signature for the data; attach the first signature to the data; calculate, after transferring the data to the different circuitry or the external IC, a second signature for the data; extract the first signature corresponding to the data; compare the first signature to the second signature; and generate a signal based on a comparison of the first signature to the second signature.
