Performing authenticated encryption with nanoscale phenomenon

Recent progress in nanotechnology has focused on applying nanoscale phenomenon in physical layer or device level applications. In this paper, we show that nanoscale phenomenon cannot only be used in physical layer, but also in high layer application such as communication protocols. In this paper, we study the possibility of performing authentication and encryption based on quantum entanglement, which is a phenomenon available only at the nanoscale level. Unlike classical authentication and encryption algorithms, the security of this protocol is based on nanoscale physical laws, instead of any unproven mathematic conjecture.
