Abstract
We present a new model to realize true random one-time pad (OTP) encryption using DNA self-assembly. OTP is an unbreakable cryptosystem if the pad (random key) is truly random, never reused, and kept secret. Mathematical algorithms can generate pseudo-random numbers only. “True” random numbers can be generated from a physical process such as thermal noise. In this work, we propose a new tile-colony algorithm that can utilize the DNA hybridization process as an effective source for the random key construction, and discuss the error tolerance of this method. Our results indicate that the molecular computation using DNA motifs will provide promising OTP applications.
