[Cryptography] "On-chip random key generation done using carbon nanotubes"

[Jerry Leichter]

Simplified idea:  Prepare an area on a silicon die with a number of connection points.  Apply an aqueous solution of carbon nanotubes.  If you set the situation up right, 50% of the connections end up populated - but at random, the locations are determined by complex random motions in the solution.  The resulting array is delicate - standard de-capping techniques will destroy it, so there's (currently, attacks only get better) no known way to read it.  Compatible with existing chip processes.
