A true random number generator based on solution-processed semiconducting carbon nanotubes

Nanowerk.com - 12 июля, 2017 - 11:56
New work demonstrates that one of the most important security primitives, i.e. a true random number generator (TRNG), can be realized within the rigorous constraints required for future Internet-of-Things electronics. The solution-processability of semiconducting single-walled carbon nanotubes allows to meet these strict constraints by simultaneously enabling small-scale, low cost fabrication of low-power, ultra-thin, printable, and mechanically flexible security devices. This presents a significant milestone in enabling higher level cryptographic solutions using scalable solution processing.
