Low power random number generator using single electron transistor

Abstract

Realization of high-quality random number generator (RNG) is essential for secure communication. In this paper, a RNG, which utilizes single-electron phenomena, is proposed. A room-temperature operating titanium oxide single-electron transistor(SET) is considered. Electron pocket is used as a high-quality, ultra-small RNG. In the proposed RNG, a stochastic single-electron capture/emission process is utilized to generate the 16 bit random numbers. Because of its small-size and low-power, it has potential to change the future of encryption.
