DNA encryption algorithm based on Huffman coding

Today, the transmission of hypersensitive data through public communication, poses a real problem for an unauthorized recipient which makes information security very important. The basic idea behind the proposed research work is to exploit the robustness of the genetic material in order to improve and outperform the performance of other conventional algorithm. In this paper, Huffman coding method has been adopted to develop a new and efficient symmetric DNA encryption algorithm. Firstly, the algorithm codifies the secondary DNA key which is extracted from the main DNA key according to Huffman coding. Then an XOR is applied between the coded DNA sequence and the plain-image. And in order to strengthen our algorithm, we have performed diffusion with a permutation box.
