FPGA Implementation of Biological Feature Based Steganography Method

Due to the fast development of information technology, secure communication is important. To ensure secure communication we need to send an encrypted message so that it can be read only by the expected recipient. There is some existing method which is used for secure communication like cryptography and its limitation is adversary knows about your message and it impacts its security level. In order to overcome the above limitation, a proposed DNA steganography method provides a greater level of security and the adversary has no idea about you hiding something. The proposed steganography method consists of DNA computing, RSA algorithm, and LSB embedding. DNA computing is a branch of computing that performs computations using DNA molecules. The RSA algorithm is a frequently used public key cryptographic algorithm for secure communication. Finally, the proposed DNA computing-based steganography was implemented using Xilinx and MATLAB and the RSA and DNA mapping have been done in Verilog and LSB embedding has been done in MATLAB. The RSA and DNA mapping have been simulated using Questa Sim-64 10.6c and implemented on vertex 7 using Xilinx ISE 14.7. The LSB embedding is implemented using MATLAB program in MATLAB R2022a.
