Text Encryption Approach Using DNA Computation and Hyperchaotic System

“Security” has formed into a critical concern in the digital data storage and transfer via communication that is not secure channels, which can be addressed by employing trusted encryption methods. Because of its remarkable superior qualities, such as simplicity, high security, and speed faster, chaos-based encryption algorithms are becoming more prominent. Furthermore, employing DNA in cryptography opens a new area due to three factors: storage capacity, computation power, and parallelism. “This paper for text encryption, a hyperchaotic sequence and a DNA sequence are used together. The intensity levels of an input text are translated to a serial binary digit stream, and the hyperchaotic sequence scrambles this bitstream globally. To achieve a robust encryption performance, DNA operations are done between the hyperchaotic sequence and the DNA sequence. The findings of the experiment show that the encryption algorithm outperforms state-of-the-art approaches in terms of quality, security, and robustness. resistant to brute force attacks. and has a bigger key space.
