Combining DNA Encoding and Chaos for Medical Image Encryption

A vast volume of digital electronic health records is exchanged across the open network in this modern era. Cross all the existing security methods, encryption is a dependable method of data security. This study discusses an encryption technique for digital medical images that uses chaos combined with deoxyribonucleic acid (DNA). In fact, Rossler's and Lorenz's chaotic systems along with DNA encoding are used in the suggested medical image cryptographic system. Chaos is used to create a random key stream. The DNA encoding rules are then used to encode the key and the input original image. A hardware design of the proposed scheme is implemented on the Zedboard development kit. The experimental findings show that the proposed cryptosystem has strong security while maintaining acceptable hardware performances.
