Secure Data Communication Using DNA Computing Adaptable to Wireless Sensor Network

Due to the proliferation of electronic devices such as mobile phones, tablets, laptops, desktops, e-drives, hard drives, etc., transferring information in the form of images through the Internet has become an essential practice in this digital era. Red, green, blue (RGB) images are used to store or share information, such as medical imaging for disease diagnosis, e-learning, online shopping, defense services, personal images, and much more. Adversaries are trying to steal this critical information from images for their gain or personal interest. Hence, we need to prevent an adversary from misusing this crucial information using encryption algorithms. This chapter aims to provide a new, secure, and fast encryption algorithm for RGB images in deoxyribonucleic acid (DNA)-encoded domain involving random sequences generated by arithmetic progression (AP) and logistic map associated with generalized Vigenere-type table suitable for wireless sensor network (WSN). The randomness of generated sequences is performed using the National Institute of Standards and Technology (NIST) statistical suite test, and the results are provided in Appendix. The proposed encryption algorithm provides a huge keyspace and is robust against brute-force, dictionary, side-channel, correlation, differential, cropping, noise, chosen cipher, and plain image attacks. The various security analysis is performed on standard test images to demonstrate the proposed algorithm's efficiency and security. Further, a comparison with other competing existing algorithms is shown. The analysis results conclude that the proposed algorithm can opt for practical application.
