Abstract:
A scrambler/descrambler module included in an integrated circuit device is operable for receiving a scrambling key and constant data that is unique to the integrated circuit device. The scrambler/descrambler module includes a first layer or circuit arrangement that uses a scrambling key to generate first scrambled data. The scrambler/descrambler module includes a second layer or second circuit arrangement that uses data that is unique to the integrated circuit device, and that is constant over the life of the integrated circuit device, to scramble the first scrambled data to generate second scrambled data.
