Abstract

Security is today’s foremost concern over the transmission channel. Quantum computing is a very potent tool in the research of a secure communication channel. Godel code encrypts a number that is allocated to each alphabets of the message, thereby obtaining a sequence of natural numbers that signifies a sequence of symbols. The mapping between the plain text to Godel code is done by a DNA sequence. The idea of using quantum computing and DNA code set encoded with Godel’s numbers to perform the quantum key distribution scheme is that each qubit pattern has its own unique properties and so, using a scheme that applies both scores over a scheme that uses any one alone. In this paper, a plain text is first transformed to its DNA equivalent sequence that is further encoded using Godel code to obtain a first level of encoded message. This message is then encrypted using a key that is obtained by a quantum key distribution protocol to guard against the threats in the transmission channel.
