ABSTRACT
Software alone cannot satisfy all smart card requirements. Manufacturers must offer additional functions in hardware. The authors describe true random-number generators and an Advanced Encryption Standard computation unit; two different special-purpose hardware blocks that can be integrated on the silicon substrate along with the usual functional units of a smart card microcontroller.
