Single-electron random-number generator (RNG) for highly secure ubiquitous computing applications

摘要: Since the security of all modern cryptographic techniques relies on unpredictable and irreproducible digital keys generated by random-number generators (RNGs), realization high-quality RNG is essential for secure communications. In this report, a new RNG, which utilizes single-electron phenomena, proposed. A room-temperature operating silicon transistor (SET) having nearby an electron pocket used as high-quality, ultra-small RNG. proposed stochastic capture/emission processes to/from are detected with high sensitivity SET, result in giant random telegraphic signals (GRTS) SET current. It experimentally demonstrated that generates extremely sequences at room temperature, spite its simple configuration. Because small-size low-power properties, promising key nanoelectronic device future ubiquitous computing systems highly mobile communication capabilities.
