Encryption Chips

Faking crypto chips for public algorithims is theoretically more difficult, because its simple to create a DES_verify routine to make sure your DES chip is working right.

a) chips do not need makeup b) t'were me, I would just fix the chip so that instead of 2^56 (DES) keys or whatever, the PRNG was "fixed" so that the total keyspace was only 2^32 for instance. Enough to be nearly impossible to check but small enough for a brute force engine to zip through in seconds *if you knew the algorithm*. The nice thing about am implimentation in software is that the code can be examined for just this sort of thing *on a randomly selected operating unit*. - hard to do with a chip. Warmly, Padgett
