Hybrid approach of image encryption using DNA cryptography and TF Hill Cipher Algorithm

Abstract

The Hill cipher algorithm is one of the symmetric key algorithms that have many variations but still not suited for all zeroes plaintext block. Chosen-plaintext attack can be possible on Toorani and Falahati Hill Cipher Algorithm by two closely related variants of Hill Cipher. In this paper we have presented a new approach of Hill Cipher (RDHili Cipher) using DNA cryptography and TFHiII Cipher to overcome the drawbacks of TFHili. We implement this algorithm for image encryption in which firstly the image will be converted into binary value and the nibble of binary value will be rotated, then it will be converted into DNA, and then DNA to Amino Acids. Secondly TFHiII Cipher can be applied on Amino Acids.The output is measured for the security level based on Correlation, histogram and entropy. The experimental results showed that the combination technique resulted in a higher entropy value and lower correlation, and a more uniform histogram, compared to the Hill Cipher, affine Hill, TFHiII and SVK Hill Cipher. This implies the good quality of the retrieved image compared to the original one.

Image encryption using finite-precision error

“…The cipher algorithm decreases the correlation of between adjacent pixels. See more details in [68] .…”

A Novel DNA Sequence Approach for Network Intrusion Detection System Based on Cryptography Encoding Method

“…Any type of data such as text, image, audio or video can be encrypted via DNA cryptography [6]. Image encryption depending on DNA cryptography and hill cipher is established [7]. In addition, the encryption system is provided that depends upon the using of DNA and a key length of 256 bits [8].…”

A Multilevel Image Encryption based on Duffing map and Modified DNA Hybridization for Transfer over an Unsecured Channel

“…DNA Hybridization is a technique in which we have to convert the image bit sequence to DNA sequence basing on nucleic acid bases [2]. As we know that every DNA sequence is build by four natural nucleic i.e Adenine(A),Thymine(T),Cytosine(C) and Guanine(G) following the complementary condition that Adenine(A) is opposite/complimentary to Thymine(T) and Cytosine(C) is opposite/Complimentary to guanine(G).It is common in DNA sequencing where the binary data was replaced by the nucleic acid bases .Where the binary sequence 01 is replaced by A and its complementary 10 is obviously replaced by T similarly 00 is replaced by Cytosine(C) and 11 is replaced by Guanine.…”
