ABSTRACT
The rapid advancement of technology has increased the need for robust cybersecurity measures to protect sensitive data and ensure secure transactions in the digital world. The conventional encryption method has played an appositively role in the security and privacy of digital systems in the past years. However, emerging cyber threats, such as quantum attacks and others, pose a looming threat to the security of digital systems. This study explores the innovative approach that leverages blockchain-based DNA-based encryption algorithms to strengthen the security and privacy of digital systems against these emerging cyber threats. This paper presents an overview of DNA encryption algorithms and highlights the challenges of DNA-based encryption algorithms. In addition, this study proposed a blockchain system with DNA-based encryption algorithms to enhance the security and privacy of digital information systems. Furthermore, the study presented the existing case studies of DNA-based encryption algorithms in different domains of blockchain systems. Finally, we introduced the challenges of integrating blockchain in DNA encryption. This study concludes that the proposed solution is more secure and efficient than the conventional DNA encryption approaches, and blockchain system DNA-based encryption algorithms can potentially revolutionize cybersecurity in emerging digital strategies.
