The prime concern in data communication over a transmission channel
is the security of the data which is being exchanged amongst the sender
and the receiver. Of late DNA based cryptography has emerged as an
alternative to data encryption in the research of secure communications.
In contrast, the axioms of quantum computation have greatly impacted
the study of cryptoanalysis and network security according to recent
trends.
The idea of using quantum computing using DNA encoding to perform
the quantum session key exchange is that each cipher-text pattern has
its own unique properties and so, using a scheme that applies both is
more secured than using any one alone.
Message exchange amongst the two participants is established through
quantum channels with non-orthogonal superposition states. The
experimental setup is also discussed. Various encoding schemes, such
as use of super-increasing Knapsack sequences, Fermat Number and
Gödel Code have also been explored to protect the quantum key
distribution procedure from different types of security concerns.
The significant advantage of this technique lies in the ease of detection
of any malicious intervention in the communication channel and how
by computing the bit error rate which is a function of the noise on the
communication network is discussed in my work.
