Over 850 megabytes are required by the automated design system to define the functions of the chip. Power ratings are currently estimated at 3.5 milliamps per MHz, i.e. at 10 Mhz and 5 volt DC, power consumed is 175 milliwatts. These estimates will be refined as data are taken into the actual chips. As you can see, both chips fall within the power requirements of hand held, battery-operated devices. Yes, it will.
Key management is handled by an algorithm based on a public-key exchange technique.
